What if someone filled wrong application form for jee advanced 2020

Hello Lalita,

Assuming that your question meant filling in wrong details in the application form for JEE Advanced 2020, it is to be noted that form corrections are not entertained or allowed after final submission . Before a candidate proceed to the first part of the application, he/she is expected to read the instructions and guidelines carefully. The same applies , while filling in the details too. After filling in the details , before clicking the " Final Submit" option in the last page, the candidate will have a chance to correct any mistakes by clicking "Edit Registration Form". This is only chance for correction hence, one must check several times before clicking final submit. If it is a very small mistake you may try contacting the officials by calling or mailing them,at jeeadv@admin.iitd.ac.in, if you are lucky they  may resolve the issue. Now if you mean, the whole application is wrong ,in the sense major mistakes, I am afraid you may have to register again with a new account. If you have not paid the fee yet , then there is no harm in doing this .  But if you have paid , then I am afraid its too late and  you have to pay again for the new application, as they do no refund the fee. Hope this was helpful.

All the best.
