hi,

see at this score you have less chances for  iits, however since you have qualifies you may participate in counselling process, as per previous years score you have chances in nit agartala, nit arunachal pradesh, nit meghalaya. but I suggest you also to try to apply in state government colleges, delhi university, banaras hindu university , jadavpur university also, some of the colleges has separate entrance test and some offers admission based on graduation marks for msc courses.
