You are what most people would call “a competitive applicant”. You are a legacy though so you should be a tad bit more optimistic. I’m not seeing a huge spike in your application though. I can infer that you’re interested in science and music, but once again I don’t see a “gem” in your application that clearly put you above all the other tens of thousands of applicants. BTW if you’re applying for something in STEM I’d definitely keep an open mind about going somewhere else. I know a TON of people who’ve gone to Harvard for STEM majors and transferred out. Do realize that a degree from MIT, Northwestern, Stanford, UCberk, Carnegie Mellon, Cornell, Johns Hopkins, etc. will look more impressive than one from Harvard when applying to jobs. I’m from NJ and NJIT (~60% acceptance rate) has a better STEM school that ranks higher than Harvard and Yale. I will advise you to choose the school that will give you the greatest opportunity to get the job you want, not necessarily the one with the most prestige.
