CBSE Class 12 Compartment 2026 Minimum Marks to Pass Each Subject

To clear the CBSE Class 12 Compartment Exam 2026, you must score a minimum of 33 marks out of 100 in the failed subject — that is 33% — and both the theory and practical or internal assessment components must individually meet the 33% threshold.

The CBSE Class 12 Compartment Exam 2026 is scheduled for July 15, 2026. It gives students who failed in up to two subjects in the main board examination a second opportunity to pass and complete Class 12. Knowing the exact passing marks for each component helps you plan targeted revision rather than aiming blindly.

• The overall minimum passing mark is 33 out of 100 per subject (33%).
• For an 80-mark theory paper: minimum 27 out of 80 in theory.
• For a 70-mark theory paper (Physics, Chemistry, Biology): minimum 24 out of 70 in theory.
• For 30-mark practicals: minimum 10 out of 30; for 20-mark internal assessment: minimum 7 out of 20.
• Practical and internal assessment marks from the main board exam are carried forward — you appear only for the theory paper in compartment.

CBSE Class 12 Compartment Exam 2026 Minimum Passing Marks

CBSE mandates a minimum of 33% marks in each subject for a student to be declared passed. For a 100-mark subject, this means you need at least 33 marks. This applies in both the main board exam and the compartment exam. The threshold must be met in each component — theory and practical — individually, and in the combined total. The table below summarises the passing requirement by component:

Subject-wise Minimum Marks: Theory and Practical Split

The theory-to-practical ratio varies by subject. Science subjects — Physics, Chemistry, and Biology — carry a higher practical weightage than commerce and humanities subjects. Geography also follows the 70+30 pattern. The table below shows each subject’s paper pattern and the minimum marks required in each component for the CBSE Class 12 Compartment Exam 2026:

Important: Practical and internal assessment marks are carried forward from the main board exam. In the CBSE Class 12 Compartment Exam 2026, you sit only the theory paper of the failed subject — you do not re-appear for practicals unless CBSE specifically requires it.

How CBSE Calculates Compartment Exam Marks

CBSE follows a straightforward method to arrive at your final subject score after the compartment exam. Understanding this calculation lets you set a realistic theory target based on the practical marks you have already secured:

1. Your compartment theory score replaces the original theory score in the failed subject.
2. The practical or internal assessment marks remain unchanged from the main board exam and are carried forward automatically.
3. Final subject score = Compartment theory marks + Carried-forward practical or internal marks.
4. If this total is 33 or above out of 100, you are declared passed in that subject.
5. CBSE issues a revised marksheet reflecting the updated score after compartment results are announced.

Example: You scored 8 out of 30 in Biology practical (carried forward) and 14 out of 70 in the theory paper (fail — combined 22/100). In the compartment exam you score 32 out of 70 in theory. Your new total = 32 + 8 = 40 out of 100 — Pass. Your overall aggregate across all five subjects is then recalculated using this revised score.

Grace Marks Policy in CBSE Compartment Exam 2026

CBSE has a grace marks provision that extends to compartment examinations. Here is how it works:

• CBSE may award up to 5 grace marks in a subject where a student falls marginally short of the passing threshold.
• Grace marks are applied at CBSE’s discretion and are not guaranteed for every student who falls short.
• The decision is based on the student’s overall academic profile and CBSE’s internal assessment criteria.
• If grace marks are applied, the revised marks appear on the final marksheet issued by CBSE.
• Always aim to score 33 or more independently — do not build your preparation plan around receiving grace marks.
