Chance me for MIT, IVY leagues and other top universities

You certainly have a competitive profile. But as you have heard, getting accepted as student from India with financial aid will be difficult. Especially in this era where many schools are struggling.

But it doesn’t hurt to try. Just make sure you have some good backup options. Have you taken the JEE? Why not any of the IITs? They have some of the best maths/physics in the world?
