<p>Your GRE’s are pretty good (although a 780+ Q would help), but that 3.5 AW hurts you. How much? At most schools I would say it is not an issue, but some really hot students apply to MIT and sometimes it is the small stuff that makes the difference. In other words - everything is important at this level. Bear in mind that several other schools admitted you, so it might not be a deciding factor, it might just be “fit”. MIT is notorious with several departments taking a long time to notify people, often not until February or March. They know they are generally the top choice, very very few people turn them down, so they do not feel compelled to rush - they don’t need to leave time to fill the spot if you say no.</p>
<p>Of the schools you mentioned, I am not too familiar with Imperial College, but all of the rest are excellent choices. I would consider it irresponsible to suggest one for you, as that is a very individual decision. Visit them (if possible) and see which programs, departments, and faculty you like the best.</p>
