Hello Hima Kiran Reddy ,

To get admission in IITs, NITs, IIITs, GFTI colleges, you need to register for JoSAA counseling.

For JoSAA your category rank will be considered....while in CSAB counselling your CRL rank will be considered....There are limited seats for a particular category in any branch.

In JoSAA counselling, first your category will be seen for your First preference or choice then it will be checked that if seat is available or not fir your category ,if seat is not available then your next preference will be checked.

You are less likely to get a seat in josaa counseling for B.arch course.....but you can try in csab counselling....csab counselling registration is started from 28th Nov

You can check Last year JoSAA and CSAB counselling cut off according to the counselling Rounds, branch and category through the following links....
