770 + 770 does not equal 1500. Assuming this was a typo.
Why would you have both Columbia/NYU and Dartmouth? Two very different schools; the only thing they have in common is Ivy League/Prestige.
You need more safeties. I didn’t appreciate being told that when I first posted here, but I am so glad I have a good amount of safeties alongside my reaches. You’re obviously prestige shotgunning—picking schools solely based on prestige and not fit—which is not a winning strategy and will come back to bite alongside your lack of financial awareness (especially if your mom is still studying). You don’t even have any targets. They are all reaches with one obvious exception.
You’re a good student. But there are too many good students out there. SAT (assuming you did get a 1500) is amazing but not stunning, GPA is good. Extracurriculars and awards are all over the place and just seems like your prestige reaching. French Contest? Hack Club? Nebulous internships and nonprofit chairs? It doesn’t really seem like you’re going anywhere besides resume padding. It can obviously be true that you are interested in Math/Psychology/French/Etc, but realize that this might throw AOs off. Obviously 1) you can’t go back in time and 2) your ECs are still impressive on their own, so what I would do is order them by major. You wanna do math? Put the math ones towards the top, and maybe do some more math stuff
Since you’ve moved around, try and think about where you were happiest. Do you see yourself academically and personally successful in the city or the suburbs? Do state politics (red/blue) affect you? Any programs that draw your eye? I wouldn’t go to Columbia even if I got in with money just because I couldn’t focus in a city and my grades/happiness would be lower than if I went to a lower-ranked suburban school.
You asked for honesty, and here it is. Figure out what you want for yourself before getting hyper focused on a certain group of colleges.
Edit: Lehigh, Fordham, Villanova, GWU, Stony Brook, and Northeastern might be work a look.
