CBSE Passing Marks, Grace Marks & Best-of-Two: Everything Explained
Understanding CBSE pass criteria properly can make the difference between a pass and a compartment. The basic rule is 33% across theory and practical combined, but practical subjects have separate minimum requirements. Grace marks apply in specific circumstances — but should not be relied on as a safety net.
CBSE passing rules at a glance (indicative)
| Scenario | Rule |
|---|---|
| Minimum to pass a subject (theory only) | 33% of theory marks |
| Minimum to pass a practical subject | 33% in theory component AND minimum marks in practical component (check per subject) |
| Internal assessment component | Generally counted towards total marks — poor internal marks can affect overall percentage |
| Grace marks | CBSE may apply grace marks to help borderline students pass — confirm current rules each year |
| Class 10 best-of-two (from 2026) | Subject-by-subject: whichever is higher between Phase 1 and Phase 2 is used for the final certificate |
Indicative only. Confirm exact passing and grace-mark rules on the official CBSE website for your specific session and subject.
Grace marks are not guaranteed: CBSE may apply limited grace marks to help borderline students pass, but this is at CBSE's discretion and should not be treated as a fallback plan. Study to meet 33% through your own performance.
Frequently asked questions
Can a student fail in theory but pass the subject overall due to practical marks?
No. For most practical subjects, you need to meet the minimum marks in both the theory and practical components separately. High practical marks do not compensate for a very low theory score.
How is percentage calculated in CBSE Class 12?
CBSE Class 12 percentage is calculated on five main subjects (or as per the prescribed formula for your programme). Add the marks in the five subjects, divide by the total marks, and multiply by 100. Confirm the exact calculation method for your subject combination on the official CBSE portal.
