Passing Marks Out of 80 In Board Exam For Class 10

In CBSE Class 10, most subjects follow the 80 marks theory + 20 marks internal assessment pattern.

To pass:

  • 27 marks out of 80 in theory are compulsory

  • 7 marks out of 20 in internal assessment are compulsory

Both components are evaluated separately. Even if the total aggregate is above 33%, a student will fail if they do not clear either the theory or internal assessment individually. This makes understanding the passing marks out of 80 in board exam for Class 10 extremely important.

CBSE Passing Marks for Internal Assessment (20 Marks)

Internal assessment plays an important role in CBSE evaluation. It includes periodic tests, assignments, notebook submission, projects and practical work.

For an internal assessment of 20 marks, students must score 33%, which comes to 6.6 marks, rounded off to 7 marks.

CBSE clearly states that both theory and internal assessment must be passed separately. This makes internal assessments just as important as final exams.

How to Calculate CBSE Passing Marks?

Here is a simple calculation for better understanding:

CBSE Class 10

  • Theory (80 marks): Minimum 27 marks

  • Internal (20 marks): Minimum 7 marks

Example:
If a student scores 31 in theory and 10 in internal, the total is 41/100 → PASS

CBSE Class 12

  • For 80 + 20 pattern: 27 + 7

  • For 70 + 30 pattern: 23 + 10

Example:
If a student scores 30 in theory and 12 in practical, total = 42/100 → PASS

What Happens If a Student Fails to Score Passing Marks?

If a student fails to secure the required passing marks, CBSE provides multiple options:

  1. Students failing in one or two subjects can appear for compartment exams in the same academic year.

  2. Students failing in one or two subjects can appear for supplementary exams. This gives students another opportunity to pass without repeating the year.

  3. In some cases, CBSE may award grace marks if a student falls short by one or two marks.

  4. If a student fails in more than two subjects, they must repeat the academic year.
