With an unweighted 4.0 GPA (which I interpret as all A’s), and a large number of AP classes, I am surprised that you are not in the top 10% of your class. I am having a bit of trouble understanding this. I do not think that rank matters in this case unless I am missing something. Straight A’s plus your strong rigor and strong SAT score to me suggests that you are academically qualified for any university. Of course your reaches will have many more academically qualified applicants than they have places to put them.
MIT is a “fit” school. You need to want to work very hard in tough classes for it to be a good fit for you. What I see in your post suggests that it probably is a good fit, but make sure that you agree. To a large extent I might say the same thing about Georgia Tech. As one example note that your 790 math SAT score is excellent, but is just average at MIT.
If you get accepted to Georgia Tech, and assuming that you are fine with working hard for four years, then it is a VERY good university. I am not sure that I see the point in going anywhere else and spending a lot more (unless you qualify for a lot of need based aid) if you get into GT. UGA is very good also. Either would provide an excellent education, and allow you to save $$ which could be either used for a graduate program or just to help your parents to save for retirement or siblings or other expenses. Admittedly they are big schools.
I am very confident that if you ever get to applying to graduate programs, graduate admissions at Princeton, Cornell, MIT, and Stanford will all know very well how strong the undergraduate education is at Georgia Tech. The same will be true for employers.
Congratulations on your great effort and strong results in high school. This should give you a good start towards doing well wherever you end up. Best wishes.
