Hello student, 

You are having a good rank and with 1400 general rank doors of many good institutes are open for you. 

If you qualify Jee advanced then you might get a chance for Architecture at IIT Kharagpur and IIT Roorkee. 

And for NITs you can get NIT Bhopal, Hamirpur, Patna,  Raipur and Nagpur. 

But for this you have to wait for seventh round of counselling.

Hope this will help.
