My last exam went as follows:
The subject was ancient history, one of my very favourite subjects, so I had decided to go for a 13 (top-grade, which is only given for extraordinary performances). So I studied quite a lot. At least a lot compared to the amount of time I usually study prior to an exam. When the day came, I didn't feel totally ready. I knew if I drew Alkibiades' or Aristofanes' speeches I wouldn't do very well. But if I drew Socrates or Oedipus, I would have a chance to get that 13. So I go in and draw. Alkibiades' speech. Crap. In the preparation room, I noticed how little I knew about it, and I almost panicked. The teacher came in 4 minutes earlier than I had thought (!) so I wasn't ready at all. I thought it was going to go completely wrong... but then I used my ability just talk from one end and keep talking, figuring things out while I talk and drawing conclusions I hadn't even thought about before. So at the end, after a messy and unstructured, but very inspired performance, I got a 10 (translates to a good 4 in Hungarian I guess). Phew.
