Hello Aspirant,

No, you cannot change the additional subject after successful submission.

The West Bengal Council of Higher Secondary Education (WBCHSE) was commenced in 1975.

It is an independent evaluating council accountable for administering examinations for standard XII for various government and private schools associated with this board.

WBCHSE administers the West Bengal Higher Secondary (10+2) Examinations every year.

I hope it helps.

Thank you.
