The only time I saw my daughter’s supplemental essay (and her final draft of common app after just one early peek) was just before she hit submit; and the only reason I got to see those then was because I insisted on doing so before giving my signature for ED/credit card details. Now that might be too hands off for some here, but it really was her essay. FWIW, she had a counselor, who didn’t like her supplemental essay (I did, but it was a fait accompli by then anyway). It really was her essay. She got in.
