At the last session the Old English was the worst examination. You know, the most insulting thing is that you read up for them (exams, I mean), but it's useless. The head is empty again and you're nervously trying to remember the most important theses or just definitions, but then you just get your mark (of which you're not satisfied) and go outside to smoke... You may just guess what happened to your brains...
How do you read up for your exans? Maybe, you have some system of preparing?
