Hi Arjun

MIT is the finest college in the world and is a dream of many students including Indians. It is not really easy to get there. You need to start working towards since a long time. If you are aiming for undergraduate course you should have a great SAT score(above 1550/1600) else the top GRE scores if you're looking for Masters. You should write an impressive application, have lots of letter of recommendations from teachers and international/national Olympiad certificates also are a big boon. Show passion in the subject you want to pursue and prove it.

All the best!
