I applied to CUNY GC musicology, and got an email from a professor the day after Christmas, saying he's missing my writing sample...
He said he was just "reading through" app. materials, so I'm not sure if that was part of the official action or just his own.
(btw... I thought I uploaded my writing sample through the online app, so if it wasn't him I would have never sent them my writing... thank god. )
I don't think that matters. Grade is important... not the number of semesters
and besides, like the person above said, they will ask you for a midyear grade report(when you're accepted) if they want to see your senior transcript.
Good luck! I'm also a college senior applying for Ph.D programs...
