These are sources my conclusions/responses were based upon; also these two websites will help you if you have more questions:
Class Profie: http://mitadmissions.org/apply/process/stats
CDS: http://web.mit.edu/ir/cds/2016/c.html
I encourage you to check C7 of CDS.
790 M 700 EBRW
// I’m not sure what you mean by EBRW, but if 790+700 = 1490 is your SAT score, then it’s very low.
SAT IIs: 750 Math II, 720 Chemistry
// SAT 2 scores are very low as well for MIT.
GPA: 4.3734
// MIT doesn’t publish high school GPA, but based on its difficulty, your GPA seems to be on average.
Rank: 9/364
// 97.5th Percentile seems OK/above average
12 APs taken by the end of this year ( four 4s and one 5)
// OK
Subjective:
ECs: intern for a global company, Debate captain, summers spent enriching my learning
//Internship is separate and should go into work experience. Your ECs are very poor. Also your work experience doesn’t look special.
Essays: Show “me” to the best of my ability, lots of anecdotes and attention getters
// I’ll just assume you wrote a fantastic essay.
Interview: Decent, I connected with my interviewer some and was honest in my answers
// I’ll just assume you had a fantastic interview
Conclusion:
You stand very poor chance at MIT, when MIT already is a reach school for everyone. Especially, your SAT I and SAT IIs are very poor; your ECs are also very poor. I don’t think you will get in, unfortunately.
