my cmr 6600 and categry 990 (sc) which college i will get

Hello,.
Since you are from a reserved category so you can participate in the councelling process on the basis of your category merit rank.
Since your rank is way too high ,so you can get admission in in some of the nift centres only. There also you might not get the desired course. Hopefully you can get the following centres.
Nift raebareli
Nift Shillong
Nift srinagar
You can register for the subsequent rounds of councelling. It might help you in landing up in a better centre with the desired course.
You can also predict your college by browsing through the link given below.
