No worries! If you have accidentally filled out the wrong form or submitted the incorrect details, here’s what you can do:

1. Check If Corrections Are Allowed : Some exams, including JEE, allow a correction window after submission. Log in to your application portal and check if there is an option to edit or correct the details.
   
   

2. Contact the Exam Authorities : Reach out to the JEE helpdesk or the exam authority immediately for guidance on how to resolve the issue. They will provide you with the steps to either correct or withdraw and reapply, if necessary.
   
   

3. Confirm Submission : Ensure you have received a confirmation email or message regarding your form submission to make sure it was properly processed.

Acting quickly will help in case you need to make any changes before the exam.
