<p>You have to consider that MIT has seen it all. Your not going to win so national contest and shock your way into acceptance. I mean make sure your grades and standardized tests are good. Naturally thingssuch as usamo and IMO would be very good for MIT. Really, just do what you like to do and write reAlly good essays about it. Also try other schools too, here a a few suggestions for math/science
Caltech
Harvard
Stanford
Princeton
Columbia
Duke
Yale (more for politics)
Harvey Mudd
Oxford or Cambridge (if you want to go international these are great options)
Also, make sure you have a safety school in case everything goes wrong. By the way, don’t take the sat 2 math I and II. If you are good at math and have studied through precalculus take level II. It has a super easy curve. If you do poorly then try I.</p>
