Hi candidate,

Improvement exams are conducted by boards for students who are failed or not satisfied in their performance in class 12th. But they need to apply for improvement in continuation year.

One can apply for the subjects he/she thinks needs to be improved. But you need to pay some applicable fee for each subject. You can visit the board website for latest fees details. You need to only appear in theory paper and your practical marks will be forwarded from previous attempt. You are also do not need to go to school, you can prepare your subject you yourself. The marks that you get in improvement exam are if higher than the previous attempt will only get updated otherwise your previous attempt marks will be final.

I hope this helps.

Thank you!
