<p>While Carnegie Mellon isn’t exactly the easiest school to get into (especially if you’re going into CS), it seems to be a popular school for MIT hopefuls.</p>
<p>I second the UChicago suggestion.</p>
<p>I also remember that on the MIT admission blogs’ rejection threads last year, several people mentioned that they would be going to GA Tech. It would seem very reasonable for someone with competitive stats for MIT to get in there, even if he/she was OOS.</p>
