The thread started with consoling the student about his/her Yale anxiety (I’m all for it!) and ended with “It’s okay to make grammar mistakes in essays!” - which strikes me as a bridge too far, considering the mantra repeated my all AOs: “proofread, proofread, proofread.”
But @collegemom3717 is so right: If you are not accepted to Yale it will NOT be b/c of a handful of minor typos in your essays.
