<p>Sorry to be cheeky, I’m sure lots of people on this board can give you advice on getting started, but I’d just like to point out that it’s not at all necessary to get in to MIT. So don’t feel like you “have” to.</p>
<p>Of course, if you’re interested in doing it, go for it! Sorry for not actually being helpful. =P</p>
