*Heute Abend habe ich eine deutsche Prüfung. I think. I'll await correction.

Glad I've never had an exam in the evening though, German or otherwise. I try to pace myself with my revision so that I handle small chunks at a time. If I have a big period chock full of exams coming up, I'll vary the time I have between subjects so I don't constantly study one thing or one subject constantly. Inevitably, as the exams draw closer I give in to temptation and end up cramming just a tiny bit.
