Dear candidate,
Colleges is totally depend on the marks you got and the rank. Different states have their own criteria for seats to allote. Under state quota the 85 percent reservation for state students and under all india quota the 15 seats for the other state students.

As you have not mentioned about any state, its difficult to say about any college with any information. Very less chance for the all india quota seat as per your marks in other state. Have some possibilities in home state, not confirm.

For that here I am providing you with the link of our site portal to predict your college by just mentioning your information for the college and know you applicable colleges.
