Hey there,

Hope you are doing great.

By your JEE Rank, I can say that there are no chances to get a seat in NITs or Government colleges. As your rank is high, make sure you try for other colleges. You can also apply for NATA (National Aptitude test in Architecture) which is a national level examination to undergraduate courses in architecture. If not then try for some local colleges or private universities offering architecture.

Hope this helps..

Thanks.
