I'm going to have to focus on the MS221 entirely and just hope I can scrape through. I will put one or two days of revision in for M257, which I think should be enough to get me through that, but maybe not enough for a distinction, but it will have to be enough as I can't afford to fail MS221.
This seems utterly bizarre to people when I tell them how worried I am, since I've scored so highly in TMA's. But having books to hand, and all the time in the world makes a BIG difference.
Wish me luck!
