Under specific conditions, an optional subject can replace a core subject (marked as failed) during the final CBSE 10th result computation.

Condition

A student fails in one of the three core subjects (Maths, Science, Social Science).

Requirement

Student passes the skill subject (offered as a sixth subject)
