i did my thumb impression on the omr sheet but then invigilator told me to do it again but sideways which made 2 impressions overlap. i filled rest of the details correctly. is that going to be a problem?
Most often whenever the thumb impression is not prominent the authority would check the impression provided by you during your application form fillup. However since two of your thumb impressions were overlapping that will not cause any serious issues only if the other informations are correct. So don't panick, unless there are some unavoidable issues, your paper will not be cancelled.
All the best!!
