hello aspirant,

If you have mistakenly opted and chosen the OBC Category, even if you are not an OBC category student, then, I would like to tell you that  you cannot change the details that have once filled in the JEE mains application form.

This Year NTA has strictly announced in their official Brochure that there will be no corrections in the application form that will be made after the submission of registration in JEE mains 2022. SO, if you have made any mistake, then you would not be able to rectify that.

What you can do is that you can apply for fresh registration with different mobile number and id, so that you can at least give your JEE mains 2022 examination.

Further, if you do not want to withdraw the application form of JEE mains 2022, then you can submit the self-undertaking form of OBC category, so that you get the registration form cleared as a OBC Category student.  Then you can submit the fresh caste certificate after next 14 days.

Further, you can follow the below mentioned link to know more about the JEE mains 2022 exam and other details : https://engineering.careers360.com/exams/jee-main

I hope that this will help.
