Also, what should I study next year?

OU results time! Pass grade 2 ("Pass with Merit") - comfortably over 85% on the coursework, didn't revise enough (or, come to think of it, at all), 78% on the exam. The exam seems to have been marked a bit more generously than I would have done - I knew I'd passed by a good margin, but estimated around 70%, not 78%.

So the moral lesson there is that you can nearly always get away with a half-baked last minute rush-job, and there's no point putting in any real effort into anything in life. For some reason this is the kind of improving message that is totally absent from children's books.
