Hello,

The passing criteria remains the same for both usual and compartmental examinations for CBSE, i.e., 33 % marks.

Here is the official statement regarding the same-

A candidate must receive a grade higher than E (i.e., at least 33% marks) in each of the five external examination subjects during the main or compartmental examinations in order to be declared to have passed the test. The minimum passing score for each subject on the external examination is 33%.
