Transfiguration, urgh

Trying to please Professor Carrow in Transfiguration is like trying to hit a constantly moving target (sort of like a game of AK, I expect). And you've no idea where it's going to swerve to next.

I keep thinking I've figured out the rules, only they keep changing.

Got my exam back, with a grade that, well--just hope I don't get a Howler from Gran. I did revise for it, honest.
