Are you doing a full on writing course at uni? (I think you've told me before, but where? - how'd the A-levels go?)
The course I'm doing is English lit, and half of the module choices I take are creative writing ones (the maximum allowed/offered), so it might be a bit different.
But in the modules, there were a few people who wrote stuff before hand, and a load of people who hadn't written a thing and signed up for it to have a look really.
A friend of mine had done no writing at all, but still managed to do pretty well.
So I don't know really.
