To answer the question of the thread, try the best you can. Harvard is very unpredictable, and so are the ivy leagues. Don’t be discouraged and embrace the little bits of advantage you do have! (:
To clear everything up, nobody “takes someone’s spot” because nobody is entitled to a spot, even with hooks like 4.0 or URM, especially not at such an elite college. All you can do is try your best and hope for the best. It’s very unpredictable!
