Is it extracurriculars, recommendations, essays, interviews, personality, leadership, character. What is it?

Yes.</p>
<p>Once your numbers satisfy a certain threshold, they don't matter too much anymore. After the initial read, the student with a 2400 isn't treated any differently from another talented student with a 2200 simply on the basis of SAT score, but both applicants are evaluated based on what else they bring to the table and to the MIT community.</p>

People make a big deal about test scores. No one seems to believe me when I tell them that when I'm reading an application, I just glance at the test scores to get a sense of them before moving on to the more important parts of the application -- that is, who you are. But here's an example. So, I'm reading this application of a student, a pretty strong student, who's definitely overcome some challenges recently. I come to the second to last piece in the folder, which is the guidance counselor letter (the last piece is the interview report). The GC makes a big deal of the student's "scoring the magic 1600 on the SAT." Now, when I started the case, I mentally noted to myself, "Okay, this student has scores that are fine, let's move on," but it didn't really make an impact on me that the student had "the magic 1600." Yes, scoring a 1600 is something that you, your school, your parents, and your guidance counselor can be very proud of. But it's not something I'm going to bust out my highlighter for, circle in big red pen, make it the focus of your case. In fact, I don't think I have ever in my summary of a student used high standardized scores as an argument to admit that student.

<p>So it's not that students with perfect SAT scores are rejected because of some implicit bias against perfect scorers. But when they are not accepted, it's because their cases weren't as strong in other aspects as other students with lower SAT scores. (And about 50% of perfect scorers are admitted, which is a far better admit rate than the overall rate!)</p>

I keep hearing that MIT rejected a lot of people who have better stats than me. At the same time, MIT accepted a lot of people who have worse stats than me.

This is sort of an important point, even if you don't realize it -- the reason that MIT accepted people with lower SAT scores than you, but rejected people with higher scores, is that the MIT applicant pool has very high SAT scores in general. MIT could almost choose students randomly with respect to SAT score and get the same SAT score distribution as they get by carefully selecting students, just because the distribution of applicant SAT scores is so narrow in the first place.</p>
