mam i have obc certificate since it takes 3 months here for official to release the certificate and i couldn't therefore provide in January, and now its in my hand which is authenticate ,the rank and cutoff is going to come after april attempt so is there any possibility?i dont want to disrespect someone i really thankfull to you for your ans. but during form fillup nta doesn't even asks about documents of category,its only needed during counseling or during set for advance,(confirmed by my IIT friends ) my only mistake i did was i was in illusion that i need to give a scan at the time of fillup.
