I had 67% after Passed compartment . Can i give improvement in two subjects .

Mayank Thakur 1st Dec, 2019

Hey Jatin

The basic criteria set for giving improvement exam is that you must have passed in that subject.

But since you passed through compartment,  ie. you were not able to pass 1st time , so you cannot give improvement exam.

12th class marks are very important and if you can you can give 12th class exams again.

Take next decision considering your long term solution.

Best of luck!!
