I found two people on the course with whom I shall probably exchange work all my life, I published my first poem, and I have in my possession a puerile screenplay of which I am equally proud and ashamed. All wonderful things, yes, but not worth £30,000 of debt. (Fortunately, I didn't have to worry about interest rates, job placements and how to pay off my loans – a combination of savings and investments helped fund my education, as did the wonderful club that is the Oxford University Poker Society.)
I usually advise people to enrol in creative writing courses if they have the cash and the time. But to take out a loan to finance your studies? Considering the current publishing landscape – where a mid five-figure advance is considered a big deal – should give you an idea of where you might, if you're lucky, find yourself as a graduate. That is, of course, if things work out. If they don't, you could always teach.
