Hmm... good advice, thanks! I might be too late for the one at the uni, it might be filled up since studying Russian has become really popular lately. My friend actually flunked a grammar related exam but did not lose his place despite their scaremongery. I'll call them tomorrow and see if there are places left!
I just think my line of work is really stressful, so exams might just make me more stressed (I am really sensitive to stress,,,) On the other hand, the university course is much more prestigious than the options I was considering. And you can't beat free!
My experience of studying Russian in school was really rubbish and that's actually put me off signing up for a course until now. But my colleagues encouraged me.
