There are just so many scholarships which look out for brilliant students to apply to them so that the colleges who are top most in the world can create a pool of intelligentsia amongst their students and alumni’s and promote the research and technological advancements of the human race on the whole.
In face of such bigger things to think of, lack of money is a very small hindrance as all the top institutors have deep pockets to promote research and fund studies of deserving students. There are many colleges which can get the entire studying costs including the tuition fees, air fare, travels, and stay and studying expenses away.
In fact many of the Ivy League colleges in USA have opted for giving away these scholarships which do away with any sort of payments on the part of the students. The only requite for attaining such scholarships is brilliance and an excellent academic record to show.
