Hello Tanmoy,

Hope you are doing good.

So basically , improvement exam is given when you want to improve your marks or increase your score in the subjects you think is quite low.

Candidates are eligible for giving improvement examination only when they have passed in all the subjects . Improvement examination is only for your score increment or improvement.

So , you have to give compartment for physics in 2022 first, and then if you still have a low score you can appear for improvement.

First you have to successfully clear your physics compartment because a student should pass all the subjects in order to be eligible for giving improvement exam.

and very important point, is that pass certificate is awarded only after the original exam, and not in improvement examination.

I hope I'm clear to you, if you have any more doubts please confront.

Best wishes ahead.
