Bishnu, you haven't mentioned the entrance exam you are enquiring about. Neverthless, technically, what you committed was not a blunder where in you will not be eligible for document verification. When a Candidate selects "Others" it usually means the options mentioned in the application form aren't related to the Candidate's qualifications. Now when you submit your B.Sc documents, as long as they are valid and they can be authenticated, this mistake can be ignored as this doesn't cause any dent to the merit list or your eligibility in getting a seat for the exam you have applied for. So this is quite ok. There is nothing to be really worried about. If you had mentioned B. (//B.Com) Sc and then took your B.Com (//B.Com) documents for verification, that is an issue that cannot be rectified. But this is not. So please do not worry about it. By selecting "Others", you did not do a grave mistake.

Hello Bishnu.

Most probably you will be qualified for document verification. No one is supposed to do these silly mistakes you know it's matter of your career. Now as you have committed it now you have to face it. At the time of document verification they might be consider you by demanding an affidavit or any other way.

Good luck.
