Coming onto what you can expect out of this score.

You have fairly good chances to get into IIT KGP, Roorkee and Guwhati, NIT Trichy and NIT Warangal, with this score, but you might have to wait upto 3rd round of councelling.

If you want to get into MS Research program, these marks can definately get you into IITB, IITD and IITM, but you might have to face an interview for these. Also MS Research program do not have fixed duration of 2 year as M.Tech program, they can stretch anywhere from 2 to 3 years.
