Hello Aspirant,

No you will not be questioned for such shift in category in fact you can opt for your category whichever is applicable on you but make sure that you must have valid documents to verify that you really belongs to that category and deserves the reservation benefits for it.

Also for this year if you have opted OBC category as your category in JEE-Main 2022 application form then you can edit it by July 3rd, 2022 as the correction window is open right now but make sure that should be in session 2 application form if the mistake is in session 1 application then you cannot edit it now it won't put you in any trouble because if you would not be able to proof that you actually belongs to OBC category then you will be considered under General category  and the seats will be allotted accordingly.

I hope this information helps you.

Good Luck!!
