Can I get into these colleges?

hmm.. well, let me say this: your extracurricular activities will look formidable on your transcript. but your GPA will not. Duke, Brown will not accept you with that GPA, people who get in there do the same or more amount of extra activites and get ALSO a 4.0 or higher. so especially since you are a junior. You are kind of late... but as for the other universities, they will take you in but , if i were you, take your SAT's again. They are just too low. Get at least 1900 or 2000 then you'll definitely get into all of the colleges that you listed except for duke and brown. right now, because you don't any time left, (if you asked this question in freshman year i'd actually be able to aide you into a ivy league school..) the only thing left is to take your SAT again and aime for a 4.0 at least in your senior year..anyways, good luck!
