I also have similar doubts. I'm a philosophy major with a low gpa from my undergrad. So I'm filling in the gaps with art history courses from FIT and CUNY schools and volunteer work in NYC to strengthen my application. My goal is 5 art history courses and 2 language courses before 2014. I am considering Courtauld for their postbacc program as a backup, in case I dont get into my choice schools. But I would prefer to go straight into an MA program.
