CBSE Passing Marks, Internal Assessment & the 75% Attendance Rule
To pass a CBSE board exam, you need 33% in each subject — but what 33% is of (theory alone, internals alone, or the combined total) depends on your class and paper pattern, and getting it wrong is how students miscalculate their safety margin. This guide works out the exact passing mark for every common paper pattern (80+20, 70+30, 60+40), explains internal assessment, grace marks, supplementary exams, and the 75% attendance requirement that decides whether you sit the exam at all. Written for CBSE Class 10 and 12 students and their parents.
What are the passing marks in CBSE?
The CBSE passing standard is 33%, applied subject by subject: a candidate must score at least 33% in every required subject to pass the Class 10 or Class 12 board examination. This threshold comes from the pass-criteria chapter of the CBSE Examination Bye-laws, and it has been stable for years even as paper patterns, assessment schemes, and exam calendars around it have changed.
Three details hide inside that one sentence, and each one matters to real students. First, 33% of what: most subjects are split into a board-marked theory paper and a school-assessed internal or practical component, and the pattern (80+20, 70+30, or 60+40) changes the raw marks you need. Second, where the 33% must land: the bye-laws' baseline rule requires theory and internals to be cleared separately, but CBSE has relaxed this for Class 10 in recent cycles — the single most misunderstood rule in the system, covered in its own section below. Third, marks are only half of eligibility: the bye-laws also require 75% attendance, and a student with brilliant marks and 68% attendance has a problem no amount of studying fixes.
Freshness note: CBSE revises paper patterns, assessment splits, and exam structures through annual circulars — including the move to a two-exam year for Class 10 from 2026. Everything in this guide reflects CBSE's published rules and long-running practice as of July 2026, but always verify the current year's circular and your subject's question-paper design on cbse.gov.in before exam season.
Passing marks by paper pattern: the exact math
The minimum passing mark for any component is 33% of its maximum, and because board marks are awarded in whole numbers, the safe minimum is the next whole mark above that exact value. For the common 80-mark theory paper, 33% is 26.4 — so 26 is mathematically below the line and 27 is the safe pass mark. The same logic gives 24 out of 70, 20 out of 60, 10 out of 30, 14 out of 40, and 7 out of 20.
Here is the complete mark-by-mark table for every common CBSE paper pattern. The "exact 33%" column is pure arithmetic; the "safe minimum" is the whole mark you should treat as the real target, since CBSE does not publish a rounding rule for the fractional values.
| Paper pattern | Component | Max marks | Exact 33% | Safe minimum (whole marks) |
|---|---|---|---|---|
| 80 + 20 (most Class 10 subjects; many Class 12 theory subjects) | Theory | 80 | 26.4 | 27 |
| Internal assessment | 20 | 6.6 | 7 | |
| Subject total | 100 | 33.0 | 33 | |
| 70 + 30 (Physics, Chemistry, Biology and other practical subjects) | Theory | 70 | 23.1 | 24 |
| Practical | 30 | 9.9 | 10 | |
| Subject total | 100 | 33.0 | 33 | |
| 60 + 40 (subjects with heavier practical/project weight, e.g. some Class 12 electives) | Theory | 60 | 19.8 | 20 |
| Practical / project | 40 | 13.2 | 14 | |
| Subject total | 100 | 33.0 | 33 | |
| 50 + 50 (common in skill subjects — verify your subject's scheme) | Theory | 50 | 16.5 | 17 |
| Practical / internal | 50 | 16.5 | 17 | |
| Subject total | 100 | 33.0 | 33 |
Which pattern applies to your subject is defined in that subject's curriculum and question-paper design, published each year on CBSE Academic. Languages and most humanities subjects follow 80+20; lab-based sciences follow 70+30; some electives with large project components follow 60+40; and many skill subjects split 50+50. If you are unsure, the front page of any recent sample paper for your subject states the theory maximum.
The pass line is deliberately low — but percentages for college admission are not. If you want the same arithmetic pointed at a higher target than 33%, our marks needed calculator computes what each remaining paper must contribute to hit any goal, and the guide on scoring 90+ in boards turns it into a study plan.
Do theory and internals have to be passed separately?
The short, honest answer: for Class 12, yes; for Class 10, it has depended on an annually extended relaxation — verify the current year's circular. This is the question on which coaching sites contradict each other most, so here is what the record actually supports.
The baseline rule sits in the pass-criteria chapter of the CBSE Examination Bye-laws: in a subject involving practical work, a candidate must obtain 33% in theory and 33% in the practical (or internal) component separately, in addition to 33% in the subject overall. Note the small logical wrinkle: if you clear both components at 33% each, your subject total is automatically at or above 33% — the aggregate condition is stated formally but is only binding when a component rule is waived.
That waiver is exactly what happened for Class 10. When the board exam returned for the 2018 batch (the first after CCE was scrapped), CBSE announced as a one-time measure that Class 10 candidates would pass with 33% of the subject total — theory and internal assessment combined — without needing to clear each separately. The board then continued the relaxation in subsequent cycles rather than reverting. The result is two coexisting readings:
| Rule | Class 10 | Class 12 |
|---|---|---|
| Pass threshold | 33% per subject | 33% per subject |
| Theory cleared separately? | Not required under the relaxation CBSE has extended since 2018 — subject total of 33% suffices. Confirm each year's circular. | Yes — 33% of the theory maximum, independently. |
| Internal / practical cleared separately? | Not required under the same relaxation. | Yes — 33% of the practical/internal maximum, independently. |
| Subject aggregate (out of 100) | Yes — this is the operative condition: 33/100. | Yes — 33/100, though it follows automatically when both components pass. |
| Practical effect | Strong internals can absorb a weak theory paper. | Every component is a separate hurdle; internals cannot rescue theory. |
Why the hedge on Class 10? Because the relaxation was framed as temporary and renewed by circular, not written permanently into the bye-laws, and some recent commentary claims a return to stricter component-wise passing. We could not find a CBSE document announcing such a reversal, but the clean way to be safe is the same either way: plan as if the Class 12 rule applies to you. Aim for 33% in theory on its own. If the relaxation holds, you have margin; if it does not, you are covered.
Two students, same total, different fates: a Class 12 student scoring 25/70 in Chemistry theory (35.7% — pass) but 8/30 in practicals (26.7% — fail) fails the subject at 33/100 despite technically touching 33%. A Class 10 student scoring 26/80 in theory (32.5%) with 9/20 internals (45%) totals 35/100 and passes under the combined-total reading — but would fall 0.4 marks short of the theory line under the strict reading. The rule reading, not the effort, separates them.
Internal assessment: how the 20 marks are built
Internal assessment (IA) is the school-assessed component of a subject — 20 marks in the standard 80+20 pattern — awarded across the academic year rather than in a single exam. In CBSE's recent assessment schemes, the 20 marks have been composed of three strands: periodic assessment (10 marks), portfolio (5 marks), and subject enrichment activities (5 marks).
| IA strand | Marks | What it typically covers |
|---|---|---|
| Periodic assessment | 10 | Pen-paper periodic tests (usually the best scores from those conducted) plus multiple assessment modes — quizzes, oral tests, concept maps, group work. Recent schemes split this 5 + 5. |
| Portfolio | 5 | Classwork and a curated record of the student's work across the year — assignments, self-assessment, achievements. |
| Subject enrichment activities | 5 | Subject-specific practical work: speaking/listening in languages, lab work in science, maths lab activities, map/project work in social science. |
Two caveats. The exact split has varied across cycles — an earlier version used 10 marks for periodic tests, 5 for notebook submission, and 5 for subject enrichment — and schools implement the scheme per the current year's circular, so treat the table above as the recent shape rather than a permanent formula. And in Class 12 practical subjects, the non-theory component is a board-supervised practical exam and project (30 or 40 marks) rather than this IA structure, with the split defined in each subject's curriculum document.
Strategically, IA marks are the cheapest marks in the entire system. They are awarded by your own teachers, on work spread across months, with full knowledge of what is expected — and they count fully in your final percentage. A student who treats notebooks, practicals, and periodic tests as beneath attention routinely donates 5–8 marks per subject that the board exam then has to earn back the hard way. Submitting on time, keeping the portfolio genuine, and showing up for practicals is the highest-return studying you will do all year. Once results arrive, you can compute your overall percentage with the free percentage calculator, and the final grade calculator shows how theory and internals combine toward any target.
Grace marks: what CBSE actually does
CBSE has a discretionary moderation practice — the board can, and historically does, award grace marks to candidates who miss a pass threshold by a small margin. What it does not have is a published, guaranteed grace policy that students can plan around: no official document promises a fixed number of grace marks, a qualifying margin, or which components grace may be applied to in a given year.
You will find coaching and school websites quoting specific figures — "up to 5 marks," "2% of the total," and similar. Treat these as unofficial folklore. The board's moderation power exists in the bye-laws and its use became publicly visible during the 2017 marks-moderation debate, but its year-to-year application is internal to the board and can change without notice. Marksheets do not advertise the mechanics, and CBSE does not entertain grace-mark requests from candidates.
Never let a hoped-for grace mark into your planning arithmetic. The only numbers you control are the ones in the passing table above. If your practice scores hover near a component minimum — say 25–28 out of 80 — the rational response is to target 5–10 marks higher, not to assume the board will bridge the gap.
Where marginal students should actually look for recoverable marks: the internal assessment (school-assessed, still open until schools submit marks), the highest-weight chapters of the theory syllabus (sample papers reveal them), and presentation basics that reduce avoidable deductions. Those are real levers; grace is a lottery ticket.
Compartment / supplementary exams: failing one subject
Failing one subject does not cost you the year. Under the Examination Bye-laws' scheme, a candidate who passes all subjects except one is placed in compartment — renamed the supplementary examination by CBSE in 2023, in line with NEP 2020 terminology — and gets to clear just that subject in an exam held shortly after results, traditionally in July.
The traditional structure, which the bye-laws describe and generations of students have used, works like this:
- Replacement first. Before anyone is failed, the result computation applies the additional-subject rule: if you offered a sixth (or seventh) subject and passed it, it can replace a failed main subject for result purposes — the classic Class 10 case being a passed skill subject standing in for a failed Science, Maths, or Social Science.
- One subject failed → supplementary. If exactly one subject remains failed after replacement, you are placed in supplementary for it. You appear only in that subject; your passed subjects stand.
- Up to three chances. Traditionally a compartment candidate has had three opportunities: the supplementary exam soon after results, the following year's main examination, and the supplementary after that. Clearing at any attempt completes the pass.
- Two or more subjects failed → essential repeat. Fail more than one subject (after replacement) and the traditional scheme requires reappearing in all subjects the following year.
Two things to verify against the current year's circular. First, the fine print — exact attempt counts, fees, how supplementary marks appear on the marksheet — is administered year to year. Second, and bigger: Class 10 moved to a two-board-exam year from the 2026 cycle. Under the announced scheme, Class 10 candidates sit a main examination in February–March and may sit a second examination in May, with the better score counting — and the second sitting absorbs the role of the supplementary exam. Because 2026 is the first year of this structure, treat every operational detail (eligibility for the second sitting, number of subjects, result merging) as circular-dependent rather than settled tradition. Class 12 continues on the single-exam-plus-supplementary pattern as of this writing.
If you do land in supplementary: it is a normal, recoverable event, not a scarlet letter. The syllabus is the same, the pass mark is the same 33%, and a focused month on one subject is a very different problem from a year of five. Plan the retake the way you would plan any exam — the study techniques in our guides work identically for a single-subject sprint.
The 75% attendance rule for board exams
Marks decide whether you pass; attendance decides whether you appear. The CBSE Examination Bye-laws require candidates for the Class 10 and Class 12 board examinations to have at least 75% attendance, and schools certify this when they finalize the List of Candidates for the board. A student below the line without an approved condonation is simply not sponsored for the exam — there is no marks-based workaround.
The calculation cutoff matters more than most students realize. CBSE's shortage-of-attendance instructions have reckoned attendance as on January 1 of the examination year — roughly the start of the session through early January — with schools required to forward shortage cases, with documents, to their CBSE regional office around that date. Two practical consequences: perfect attendance in January and February cannot repair a shortfall that existed on the cutoff date, and the earlier in the session you check your own number, the more classes you have left to fix it. The math of recovery — how many consecutive attended days pull 68% back to 75% — is worked through in our guide to calculating attendance percentage, or you can get your exact position instantly with the attendance calculator.
When the shortage is genuine, the bye-laws provide a documented mercy route. Per the provisions CBSE has published under its Examination Bye-laws, the Board's Chairman may condone a shortage of up to 15% — that is, down to 60% attendance — in deserving cases, and cases below 60% are considered only in exceptional circumstances, such as serious illness involving prolonged hospitalization, backed by strong medical evidence. The grounds CBSE has listed include prolonged illness, the loss of a parent or a similarly traumatic event, and authorized participation in national or international sports.
| Attendance band | Board-exam eligibility position |
|---|---|
| 75% and above | Eligible — no action needed. Keep a buffer; illness in December has nowhere to hide. |
| 60% – 74.9% | Shortage, but within the Chairman's condonation range (up to 15%). School forwards a documented case to the regional office; approval is discretionary. |
| Below 60% | Considered only in exceptional circumstances (e.g. prolonged serious illness with hospitalization) with strong evidence. Do not rely on this band. |
Three process facts to internalize. Condonation is routed through the school — students and parents cannot apply to CBSE directly, so your first conversation is with your principal, early. It is evidence-driven — medical certificates, hospitalization records, and contemporaneous leave applications carry the case, and paperwork produced months later at exam time is exactly what gets rejected. And it is discretionary — "may condone" is not "shall condone." Our guide to attendance condonation and medical certificates covers what a valid certificate must contain and includes copyable application templates; the wider regulatory picture across colleges and universities is in the 75% attendance rule explained.
The cheap insurance: know your number continuously instead of discovering it in January. Track per-subject attendance from day one, keep a personal floor of 80–85%, and file any medical documentation the week you return to school — not the week the shortage list goes up.
Worked examples: real scenarios, exact arithmetic
Abstract rules become obvious with numbers. Here are three scenarios covering the cases students actually ask about.
Scenario 1 — Class 12 science student, 70+30 pattern. Ananya scores 22/70 in Physics theory and 28/30 in practicals. Her subject total is 50/100 — a comfortable-looking 50%. But 22 ÷ 70 = 31.4%, below the 33% theory line (23.1 exact, 24 safe). Under the Class 12 separate-pass rule she fails Physics despite her total, and is placed in supplementary for it. The lesson: in Class 12, the theory paper is a standalone hurdle, and practical marks — however strong — cannot vault it.
Scenario 2 — Class 10 student, 80+20 pattern. Rohan scores 24/80 in Social Science theory and 18/20 in internal assessment. Theory alone is 24 ÷ 80 = 30%, below the line. But his subject total is 42/100 = 42%, well above 33% — so under the combined-total relaxation CBSE has extended for Class 10, he passes. Under a strict component-wise reading he would need 27 in theory and would fall 3 marks short. Same marksheet, opposite outcomes — which is precisely why we recommend every student plan to the stricter standard.
Scenario 3 — the aggregate trap. Meera, Class 12, scores 25/70 in Chemistry theory (35.7% — clears theory) and 8/30 in practicals (26.7% — fails practicals). Her total is exactly 33/100. Three conditions, checked in order: theory ≥ 33% ✓, practical ≥ 33% ✗, total ≥ 33% ✓. One failed condition fails the subject. Notice what this example proves: the subject aggregate is the weakest of the three conditions — whenever both components pass, the total passes automatically — so the components are where your attention belongs.
To run your own numbers against any target — pass mark or 90% — use the marks needed calculator, or check a finished result with the percentage calculator.
How to check your own eligibility in five steps
- Find your subject's paper pattern. Open the current sample paper or question-paper design for each subject on CBSE Academic; the theory maximum (80, 70, 60, or 50) is on the front page. That tells you which row of the passing table applies.
- Write down the component minimums. For each subject, note the safe whole-mark minimum for theory and internals from the table above — 27/80, 24/70, 20/60, 17/50, and the matching internal figures — and treat the theory number as binding regardless of your class.
- Check your attendance against 75%. Compute your percentage from the school register (or track it live), remembering that eligibility is reckoned around January 1 of the exam year. Below the line? Start the condonation conversation with your school immediately, with documents.
- Verify the current year's circular. Confirm the Class 10 component rule, the supplementary/second-exam structure, and any pattern changes for your subjects from cbse.gov.in — rules on this page are stated as of July 2026.
- Plan marks with real arithmetic. Feed your pre-board and internal scores into the marks tools linked above and set per-paper targets with a cushion above the exact 33% values — 5–10 marks of margin turns a pass from a gamble into a formality.
Six mistakes that turn passable years into repeats
Confusing the two 75% rules. The 75% attendance requirement for board eligibility is a different rule from the "75% marks" criterion that JEE Main applies for NIT/IIT admission. Students conflate them constantly. Attendance decides whether you sit the board exam; the marks criterion decides engineering admission later.
Planning to 33 overall instead of 33 per component. As the worked examples show, Class 12 fails you on a single weak component. Set your floor per paper, not per subject total.
Treating internals as decoration. Seven marks out of 20 is a trivial bar — but only if the work exists. Missed practicals, unsubmitted portfolios, and skipped periodic tests are the only realistic ways to fail a school-assessed component, and every mark lost there must be recovered on a board-marked paper at much higher difficulty.
Betting on grace marks. Moderation is real but discretionary, unpublished, and outside your control. A plan that needs grace to work is not a plan.
Discovering attendance in January. By the time the shortage list appears, the calculation window is nearly closed. Attendance is a September problem that students treat as a January problem.
Trusting year-old rules. The compartment exam changed its name; Class 10 changed its exam calendar; assessment splits have been revised more than once. Whatever a senior tells you was true for their batch, the current circular outranks it.

Frequently Asked Questions
What are the passing marks out of 80 in CBSE?
33% of 80 is 26.4, so with whole-number marking you need 27 out of 80 to clear the theory paper on its own. CBSE does not publish a rounding rule for the 0.4 fraction, so treat 26 as below the line and 27 as the safe minimum. In subjects with an 80-mark theory paper, the remaining 20 marks come from internal assessment — and whether theory must be cleared independently depends on your class, as explained in this guide.
What are the passing marks out of 70 in CBSE?
33% of 70 is 23.1, so 24 out of 70 is the safe whole-mark minimum for a 70-mark theory paper. These subjects — typically Physics, Chemistry and Biology — pair the 70-mark theory paper with 30 marks of practicals, where 33% is 9.9, making 10 out of 30 the practical minimum. Class 12 candidates must clear the two components separately under the Examination Bye-laws.
What are the passing marks out of 60 in CBSE?
33% of 60 is 19.8, so 20 out of 60 is the whole-mark minimum for a 60-mark theory paper. Subjects with this pattern carry 40 marks of practical or project work, where 33% works out to 13.2, i.e. 14 marks. Check your subject's current question-paper design on CBSE Academic to confirm which split applies, because the board revises subject schemes from time to time.
Do I need to pass theory and internal assessment separately in CBSE?
For Class 12, yes — the Examination Bye-laws require 33% in theory and 33% in the practical or internal component separately, plus 33% in the subject overall. For Class 10, CBSE waived the separate-pass requirement as a one-time measure for the 2018 exam and continued the relaxation in later cycles, so 33% of the subject total was sufficient. Because that relaxation has been extended year to year rather than made permanent, verify the current year's circular before relying on it.
What are the passing marks out of 100 in CBSE?
33 out of 100. When a subject's theory and internal components are added, the combined subject score is out of 100, and 33% of 100 is exactly 33 — one of the few thresholds with no fractional ambiguity. Reaching 33 overall is not always enough, though: Class 12 candidates must also clear each component separately, so a 33/100 built from strong internals and weak theory can still fail the subject.
Is the 33% rule per subject or overall in CBSE?
Per subject. You must earn at least 33% in every required subject individually — there is no provision to average a strong subject against a weak one. A candidate scoring 90% in four subjects and 30% in the fifth has failed the fifth subject and is placed in supplementary (compartment) for it, subject to the additional-subject replacement rule described in this guide.
How is the 20-mark internal assessment divided?
In recent CBSE assessment schemes the 20 marks have been split into periodic assessment (10 marks — typically half from pen-paper tests and half from multiple assessment modes), portfolio (5 marks) and subject enrichment activities (5 marks). The exact split has varied across cycles — an earlier scheme used 10 for periodic tests, 5 for notebook submission and 5 for subject enrichment — so check the current year's assessment circular for your class.
What happens if I fail internal assessment but pass theory?
In Class 12, failing either component fails the subject — the bye-laws require 33% in theory and internals separately — so you would be placed in supplementary for that subject. In Class 10, under the relaxed combined-total rule CBSE has been extending, a weak internal score can be absorbed if your subject total still reaches 33%. Internal assessment is school-graded and failing it outright is rare; if you are at risk, ask your school about make-up assessments early.
Does CBSE give grace marks?
Sometimes, at its discretion. The Examination Bye-laws give the board a moderation power, and CBSE has historically used it to help candidates who miss a passing threshold by a small margin. The board does not publish a guaranteed number of grace marks or a fixed eligibility band, and coaching-site claims of specific figures are unofficial. Treat grace as a possibility you cannot plan for: aim for the whole-mark minimums in this guide, with a buffer.
Is 26 out of 80 a pass in CBSE theory?
On the raw arithmetic, no — 26 ÷ 80 is 32.5%, just below the 33% line, while 27 ÷ 80 is 33.75%. CBSE does not publish a rule for rounding at that margin, and any rescue would depend on discretionary moderation, which is not guaranteed. If a mock or pre-board leaves you near this edge, plan for a two-to-three-mark cushion above the exact threshold rather than betting on grace.
Is 75% attendance compulsory for CBSE board exams?
Yes. The CBSE Examination Bye-laws require candidates for the Class 10 and Class 12 board examinations to have at least 75% attendance, and schools finalize eligibility when they submit the List of Candidates. Shortage cases can be condoned by the Board's Chairman on documented grounds such as prolonged illness, loss of a parent, or authorized national or international sports participation — routed through the school, not applied for directly by the student.
Until when is CBSE attendance counted for board eligibility?
CBSE's shortage-of-attendance instructions have reckoned attendance as on January 1 of the year of the examination, which is also around when schools must forward shortage cases with documents to the regional office. In practice, your attendance from the start of the session to early January is what decides eligibility, and improvement after that cannot repair a shortfall. Verify the exact cutoff and submission date in the current year's circular.
How much attendance shortage can CBSE condone?
Per the provisions CBSE has published under its Examination Bye-laws, the Chairman may condone attendance shortage of up to 15% — that is, down to 60% attendance — in genuine, documented cases. Cases below 60% are considered only in exceptional circumstances, such as a serious illness involving prolonged hospitalization, and require strong medical evidence. Condonation is discretionary, routed through your school with evidence, and never guaranteed.
What is the difference between compartment and supplementary exams?
Mostly the name. In 2023 CBSE renamed the compartment examination as the supplementary examination, aligning its terminology with the National Education Policy 2020. The function is the same: a candidate who fails one subject while passing the rest gets a chance to clear that subject shortly after results, traditionally in July, without repeating the whole year. Older documents, teachers and mark statements may still use the word compartment.
How many subjects can I fail and still get a supplementary chance?
Traditionally one. Under the bye-laws' scheme, a candidate who fails a single subject after the additional-subject replacement rule is applied is placed in supplementary for that subject; failing more than that has meant reappearing in the examination as a whole. Rules evolve — including Class 10's move to a two-exam year from 2026 — so confirm the current provisions in the year's examination circular.
What is the sixth-subject replacement rule in CBSE?
If you offered an additional (sixth or seventh) subject and failed one of your main five, the bye-laws' result-computation provisions allow a passed additional subject to replace the failed one for result purposes. The common Class 10 case is a passed skill subject stepping in for a failed academic subject such as Science, Maths or Social Science. Which subjects may substitute for which is defined by the board's scheme of studies, so confirm your combination with your school.
How many attempts do I get to clear a supplementary subject?
Traditionally, compartment candidates have had up to three chances: the supplementary exam held soon after results, the next year's main examination, and the supplementary that follows it. Clearing at any of those attempts completes the pass. Because CBSE has been restructuring exam frequency — notably the two-exam year for Class 10 from 2026 — check the current year's rules for exactly how many chances apply to you.
What happens if I fail in two or more subjects in CBSE?
Under the traditional scheme you are not placed in supplementary for multiple failed subjects and must reappear in all subjects the following year — what the bye-laws call an essential repeat. The additional-subject replacement rule can reduce two failures to one on paper if you passed a sixth subject. Confirm the current year's provisions, since the supplementary structure — especially for Class 10 under the two-exam format — has been changing.
Do internal assessment marks count in the final CBSE percentage?
Yes. Your final score in each subject is theory plus internal or practical marks out of 100, and every percentage computed from your marksheet includes them. That makes the internal component the highest-yield marks in the system: they are school-assessed, awarded across the whole year, and historically score high. Protect them by submitting work on time — and remember that low attendance can indirectly hurt school-assessed components too.
Do the passing marks change under the 2026 two-exam scheme for Class 10?
The 33% pass threshold itself is not what the announced scheme changes — it restructures opportunities, giving Class 10 candidates a main sitting (February–March) and a second sitting (May) whose better score counts, folding the supplementary function into the second exam. Because this is a newly implemented structure, treat every operational detail — who may sit the second exam, in how many subjects, how results merge — as something to verify from the current CBSE circular.
Are the passing marks the same for Class 10 and Class 12?
The percentage is the same — 33% — and the component arithmetic (27 of 80, 24 of 70, 20 of 60, and so on) is identical. The difference is where the 33% must land: Class 12 requires it separately in theory and practicals plus the subject overall, while Class 10 has run for years on a combined subject-total reading under an annually extended relaxation. Same threshold, different strictness.
Does CBSE round 26.4 up or down for passing?
CBSE does not publish a mark-by-mark rounding rule for pass thresholds, so nobody outside the board can promise what happens at exactly the fractional margins. What is arithmetically certain: 26/80 is 32.5% (below 33%) and 27/80 is 33.75% (above it). The safe planning assumption is the next whole mark above the exact 33% value — 27, 24, 20, 17, 14, 10 and 7 for the common component sizes.
Key Takeaways
- The CBSE pass threshold is 33% per subject; with whole-number marks that means 27/80, 24/70, 20/60, 17/50 in theory, and 7/20, 10/30, 14/40 in internals.
- Class 12 must clear theory and practicals separately; Class 10 has run on a combined subject-total reading under a relaxation extended since 2018 — plan to the stricter standard either way.
- Internal assessment (typically 10 + 5 + 5 out of 20) counts fully in your final percentage and is the cheapest place in the system to bank marks.
- Grace marks exist only as discretionary moderation — no published number, no guarantee, never part of a plan.
- Fail one subject and the supplementary (formerly compartment) exam saves your year; fail two or more and the traditional scheme means an essential repeat.
- From 2026, Class 10 runs on a two-exam year (February–March + May), with the second sitting absorbing the supplementary role — verify details in the current circular.
- Board eligibility also requires 75% attendance, reckoned around January 1 of the exam year; the Chairman can condone up to 15%, and below-60% cases are considered only in exceptional medical circumstances.
- Rules on this page are stated as of July 2026 — the current year's CBSE circular always outranks any guide, senior, or coaching site.
