hi nani

first of all, there are lots of exams and lots of uploading is taking place, if you ask like this, then how will i know what exam you are speaking about and what uploading problem.

so i will tell you the common methods for several exams.

1. contact the examiner (NTA in case of JEE or NEET) and ask them to make you available to upload another one which is correct. you have to mail them

2. if you find some make changes option, then try it.

3. try to upload again

4. UGHHH.. you are in a problem now. you really have to contact the examiner and there is no other choice left.

IF YOU WERE TALKING ABOUT COUNSELLING, THEN DO ALL THE SAME PROCESS BUT CONTACT THE CONSELLING UNIVERSITY.

i hope it helps
