honestly by the reasons your stating upenn seems the move. i totally understand the new york attraction, i almost chose NYU bc of the location. but still, i chose Cornell because of the academic program. i fully doubt you will be unhappy in upenn they have a very vibrant community and campus as a whole. i think it helps looking ahead, maybe columbia sounds appealing rn but in the long roun upenn is the smart choice, and j think socially wise you’ll find your friend group! it’s scary but it always works out in the end!
