Hello Aspirant,

It is the best out of four for ISC Board learners.

Scores are computed as

(English subject score + scores in 3 best subjects) divided by 4.

ENGLISH exists as a  compulsory subject and any other 3 subjects where you have achieved impressive scores.

The whole is evaluated out of 400 and done on average to get your percentage.

I hope it helps.

Thank you.
