Yeah many people receive a shock when they get to university or college. Especially in English. That is only because for some, they do grammar again (since last time it was done was in elementary school). Since some people just don't know how to write properly. All the small rules and things.
I'd have probably fallen under the 'needs something more challenging' group, though I never got the opportunity, until college. Next semester, I am taking a whole bunch of wild courses, like psychology, metaphysics, history of english, latin and sociology.
