Hello,

According to ISC rules, you have to get minimum of 35% overall to get a pass certificate. If you fail in one subject excluding english which is the core subject of ISC, you will get the passing certificate.

However, if a student fails in two or more subjects, they will not be eligible to appear for the compartmental exams. In such a case, the student will have to repeat the entire Class 12th board exams the following year.

Hope this helps,

Thank you
