What is the Passing Criteria in CBSE Class 12 Exam Pattern?
The CBSE Class 12 passing criteria depend on both the marks scored in the written paper and the practical/internal component:
- Theory and practical/internal marks are assessed separately wherever separate passing requirements apply; passing one component does not automatically compensate for failing the other.
- Students should aim for at least 33% in every subject and keep track of the CBSE Class 12 marking scheme and subject-wise assessment pattern.
| Passing Requirement | Marks/Criteria | Details |
|---|---|---|
| 70-Mark Theory Subjects | 23/70 in Theory + 10/30 in Practical | Students need 33% separately in theory and practical components |
| 80-Mark Theory Subjects | 26/80 in Theory + 7/20 in Internal/Project | Minimum 33% required in the respective components |
| Overall Aggregate | 33% | Students must meet the applicable overall passing criteria across their main subjects |
| Failure in 1–2 Subjects | Compartment/Supplementary Exam | Students who do not meet the passing criteria may be eligible to appear for the applicable compartment/supplementary examination. |
Ques. What is the passing percentage for CBSE Class 12?
Ans. A minimum of 33% marks is required overall and within individual components.
Ques. Do students need to pass theory and practical exams separately in Class 12?
Ans. Yes, you must secure 33% in the written theory paper and 33% in the practical/internal component separately to pass a subject.
Ques. How is the CBSE Class 12 internal assessment calculated?
Ans. Calculated by your school using a mix of periodic unit tests, subject-specific project work, practical lab files, and viva voce exams.
Ques. What happens if a student fails one or two subjects in CBSE Class 12?
Ans. Failing one subject allows you to clear it via the Compartment (Supplementary) Exam held shortly after the results. Failing two or more core subjects results in an "Essential Repeat" status for the full academic year.
