As per my knowledge the category you behold is checked only at the time of counselling.
At the time of counselling you've to provide proper certificate and if failed to do so you will not be able to get admission even though you've got a good rank.

So make sure you have all the certificates with you to avoid any problems in the future.

Good luck for your preparation.
