Question

what happens if signature differs in board exam.plz help me​

Answer 1

No, it doesn't create any problem. You are the same person growing with time.

The difference in your signature if so, must be that of confidence. But literally there may not be big changes in your signature.

Even if it's changed for some reasons, the other details are also verified and confirmed regarding your identity.

It doesn't matter unless it is an exceptional case.

Don't worry.. All the best and prepare well for your exams..
