Is this a good favorite for Princeton? what do you think, what did you choose?

I wrote this:

Archetypical(Thanks SAT)

Don’t include “(Thanks SAT)”. It comes off as pretentious and, if anything, you’d rather the admissions officers think you learned the work from a book that you read independently than by studying for a standardized test that everyone takes. As for the word itself, I don’t really think it matters that much. I chose sesquipedalian because it’s ironic.
