it’s nice to see someone else on this sub looking at applying to women’s colleges!! i love wellesley and i’m definitely applying there too. i can’t speak too accurately in regards to uchicago and i know that ivies are crapshoots anyways, but i’ll try and give you my piece on all the research i’ve done on wellesley. idk what your test scores are going to turn out to be, but you should really shoot on getting a near perfect score. your ecs sound alright for wellesley, and if you do a great job in your app/essay to illustrate how passionate you are about them, it’ll serve you well. definitely write the optional writing supplement, and i feel like you have a great shot there!! at least from what i’ve read about it, i could be wrong tho. good luck!
