In short: CBSE Class 10 now has two board exams — the main exam in February and a second exam in May. The better of the two scores in each subject counts for your final result. In May 2026, 6.69 lakh students appeared for the second exam, and 78% of them appeared for score improvement (not compartment). This guide explains the exact rules, who benefits from taking the May exam, a subject-wise decision framework, and how to calculate whether the May exam is worth your time.
Last updated: October 29, 2026. Rules are based on CBSE's official circular on the two-exam system. Source: Indian Express.
What the Two-Exam System Actually Is
CBSE introduced a two-exam system for Class 10 starting from the 2025-26 academic year. May 2027 will be the second year of this system. The May 2026 data (6.69 lakh students) is from the first year of implementation. Here is exactly how it works:
| Rule | Detail |
|---|---|
| Exam 1 | February 2027 — the main board exam |
| Exam 2 | May 2027 — the second exam |
| Who can appear for Exam 2 | Any Class 10 student who appeared for Exam 1 |
| Which score counts | The better score in each subject independently |
| Is Exam 2 compulsory | No. It is optional. |
| Same syllabus | Yes. Exam 2 has the same syllabus as Exam 1. |
| Same paper pattern | Yes. Same question types, same marking scheme. |
| Internal assessment | Internal assessment marks from Exam 1 carry forward. You do not redo practicals. |
| Registration for Exam 2 | Separate registration required. Opens after Exam 1 results. |
The key rule: The better score is taken subject-by-subject, not overall. If you score 75 in Maths in February and 82 in May, your final Maths mark is 82. If you score 88 in Science in February and 80 in May, your final Science mark is 88. Each subject is evaluated independently.
What Happened in May 2026: The Data
In May 2026, 6.69 lakh students appeared for the CBSE Class 10 second exam. Here is the breakdown:
| Category | Students | Percentage |
|---|---|---|
| Score improvement (passed in February, appeared to improve) | ~5.22 lakh | 78% |
| Compartment (failed in one subject in February) | ~1.47 lakh | 22% |
| Total | 6.69 lakh | 100% |
Source: Indian Express.
This means the May exam is primarily used for score improvement, not just for students who failed. 78% of students who appeared in May had already passed in February.
Who Should Take the May 2027 Exam?
Definitely Take It
| Situation | Why |
|---|---|
| You failed one subject in February | You must appear in May to pass. This is the compartment exam. |
| You scored below 60 in a subject you need for stream selection | Many schools require 60+ in specific subjects for Science or Commerce stream in Class 11. |
| You scored below 75 in a subject required for a specific college or scholarship | Some colleges and scholarships have minimum subject-wise cutoffs. |
| You feel you significantly underperformed due to illness, anxiety or a bad day | The May exam gives you a genuine second chance. |
| Your overall percentage is below your target for Class 11 admission | A few marks improvement across subjects can change your admission options. |
Consider Taking It
| Situation | Calculation to Do |
|---|---|
| You scored 70-80 in Maths and want 85+ | Is the improvement realistic? Use the decision framework below. |
| You scored 75-80 overall and want 85+ | Which subjects have the most room for improvement? |
| You are targeting a specific school for Class 11 that has a high cutoff | Check the school's cutoff and calculate how many marks you need. |
Probably Skip It
| Situation | Why |
|---|---|
| You scored 85+ in all subjects | The marginal gain is small. Use the time for Class 11 preparation. |
| You scored 90+ overall | Very little to gain. Class 11 preparation is more valuable. |
| You have a confirmed Class 11 admission that does not depend on improvement | No practical benefit. |
| The subjects you want to improve are ones you genuinely struggled with | If you struggled in February with full preparation, May may not be significantly better without a different approach. |

The Decision Framework: Subject by Subject
Use this framework for each subject where you are considering the May exam:
Step 1: Calculate Your Gap
| Your February Score | Target Score | Gap | Realistic? |
|---|---|---|---|
| 40-50 | 60 | 10-20 marks | Yes, with focused revision |
| 50-60 | 70 | 10-20 marks | Yes, with focused revision |
| 60-70 | 80 | 10-20 marks | Yes, with focused revision |
| 70-80 | 90 | 10-20 marks | Possible, requires strong effort |
| 80-85 | 90 | 5-10 marks | Possible but uncertain |
| 85-90 | 95 | 5-10 marks | Difficult — small gains at high scores |
| 90+ | 95+ | 5 marks | Very difficult — diminishing returns |
Step 2: Identify Why You Lost Marks
| Reason for Low Score | Can May Exam Fix It? |
|---|---|
| Did not complete the syllabus | Yes — if you complete it before May |
| Weak in specific chapters | Yes — targeted revision can fix this |
| Poor exam technique (time management, presentation) | Yes — practice with timed papers |
| Anxiety or illness on exam day | Yes — May gives a fresh start |
| Genuinely weak in the subject | Partially — improvement is possible but limited |
| Careless mistakes | Yes — practice and awareness can reduce these |
Step 3: Calculate the Time Cost
The May exam is in May 2027. Between February results (expected May 2027) and the May exam, you have approximately 2 to 3 weeks. During this time, you are also starting Class 11.
| Time Available | What You Can Realistically Achieve |
|---|---|
| 2 weeks | Targeted revision of 3-4 weak chapters per subject |
| 3 weeks | Full revision of 1-2 subjects |
| 4 weeks | Full revision of 2-3 subjects |
Step 4: The Decision Matrix
| February Score | Gap to Target | Time Available | Decision |
|---|---|---|---|
| Below 33 (fail) | Any | Any | Must appear — compartment |
| 33-50 | 20+ marks | 3+ weeks | Appear — high potential gain |
| 50-65 | 15+ marks | 2+ weeks | Appear — good potential gain |
| 65-75 | 10+ marks | 2+ weeks | Consider — moderate potential gain |
| 75-85 | 10+ marks | 3+ weeks | Consider — depends on subject |
| 85+ | 5-10 marks | Any | Skip — marginal gain, high time cost |
Subject-Wise Analysis: Where May Exam Helps Most
Maths
| February Score | May Exam Potential | Why |
|---|---|---|
| Below 50 | High | Maths is formula-based. Targeted practice on weak chapters can yield 15-20 mark improvement. |
| 50-70 | High | Most students in this range have specific chapter weaknesses. Fixing 2-3 chapters can add 15+ marks. |
| 70-80 | Moderate | Improvement possible but requires strong effort. Focus on Geometry and Statistics. |
| 80-90 | Low | Small gains. Careless mistakes are hard to eliminate completely. |
| 90+ | Very Low | Diminishing returns. |
Science
| February Score | May Exam Potential | Why |
|---|---|---|
| Below 50 | High | Science has predictable question patterns. Targeted revision of Physics and Chemistry can add 15+ marks. |
| 50-70 | High | Biology diagrams and Chemistry equations are learnable. |
| 70-80 | Moderate | Focus on diagram labelling and equation balancing. |
| 80-90 | Low | Small gains. |
Social Science
| February Score | May Exam Potential | Why |
|---|---|---|
| Below 50 | High | Social Science is memory-based. More revision = more marks. |
| 50-70 | High | Map work and source-based questions are learnable. |
| 70-80 | Moderate | Focus on map work and Political Science. |
| 80-90 | Low | Small gains. |
English
| February Score | May Exam Potential | Why |
|---|---|---|
| Below 50 | Moderate | English improvement requires practice, not just revision. |
| 50-70 | Moderate | Writing formats and grammar can be improved with practice. |
| 70-80 | Low | English scores are harder to improve significantly in a short time. |
| 80+ | Very Low | Diminishing returns. |
Hindi
| February Score | May Exam Potential | Why |
|---|---|---|
| Below 50 | High | Grammar rules and essay formats are learnable. |
| 50-70 | High | Vyakaran (grammar) section is highly predictable. |
| 70-80 | Moderate | Focus on grammar and writing. |
| 80+ | Low | Small gains. |
How the May Exam Affects Class 11 Admission
This is the most practical consideration for most students:
| Scenario | Impact |
|---|---|
| You need 60+ in Science for Science stream in Class 11 | If you scored 55 in February, the May exam is essential. |
| Your school has a cutoff of 75% for Science stream | Calculate your current percentage and how much improvement you need. |
| You want to change schools for Class 11 | The new school will see your final CBSE result, which includes May exam improvement. |
| You are applying to a school with a fixed cutoff | Check if the school accepts May exam results. Most do. |
The Percentage Calculator
Use this to calculate your current percentage and what you need:
Current percentage = (Sum of best marks in all 5 main subjects) ÷ 500 × 100
| Example | Calculation | Result |
|---|---|---|
| Maths 72, Science 68, SST 75, English 80, Hindi 70 | (72+68+75+80+70) ÷ 500 × 100 | 73% |
| After May: Maths 82, Science 78, rest same | (82+78+75+80+70) ÷ 500 × 100 | 77% |
| Improvement | — | +4 percentage points |
A 4 percentage point improvement can change your Class 11 admission options significantly.
What the May Exam Paper Looks Like
The May exam is identical in format to the February exam:
| Aspect | February Exam | May Exam |
|---|---|---|
| Syllabus | Full Class 10 syllabus | Same |
| Paper pattern | Same question types | Same |
| Marking scheme | Same | Same |
| Duration | 3 hours | Same |
| Internal assessment | Counted from February | Same marks carry forward |
| Difficulty | Board-level | Same |
The May exam is not easier or harder than the February exam. It is a fresh paper on the same syllabus.
Frequently Asked Questions
Is the CBSE Class 10 May exam the same as the compartment exam?
No. The May exam serves two purposes: (1) compartment for students who failed one subject in February, and (2) score improvement for students who passed but want better marks. In May 2026, 78% of students appeared for score improvement, not compartment.
Does the May exam result replace the February result?
No. The better score in each subject is taken independently. If you score lower in May than in February for a subject, your February score is retained for that subject. You cannot do worse overall by appearing for the May exam.
When does registration for the May 2027 exam open?
Registration opens after the February 2027 results are declared (expected May 2027). Watch cbse.gov.in for the official notification. The registration window is typically 5 to 7 days.
Can I appear for the May exam in all subjects?
Yes. You can appear in any or all subjects. Most students appear in 1 to 3 subjects where they want improvement.
Does the May exam result affect my Class 11 admission?
Yes. Your final CBSE result (which includes May exam improvement) is what schools use for Class 11 admission. However, the timing matters — Class 11 admissions often start before May results are declared. Check with your target school about their timeline.
What is the fee for the May exam?
The fee is announced with the registration notification. Check cbse.gov.in for the official 2027 fee when registration opens.
