If you want give improvement exam to improve you mark in any class then at first you have to write an application to your school or college authority that you want to give improvement exam.After that you have to fill the improvement exam form.

In improvement exam you can only give the theory papers of subjects not the practical exam.

practical marks of subjects will not change because in improvement exam you allowed to give only theory papers.
