What to write?

Hi,
This is my second notebook entry and I'd like to talk about my day.
Today's been a really stressful day. This morning I did (had/took) an economics test which I didn't know how to do (I don't like economics; or rather, I don't like my economics teacher: he has a strange way of explaining things that I will never understand) and I've been studying for hours because tomorrow I have another test, a french test, and a lot of oral exams to do.

[I don't know what 'interrogazioni' means, but if you are asking if there is a better term than oral exams, then here is my answer: Based on my own school experience, an oral exam would be a fairly important test, the kind you take at the end of a school term. An oral quiz would be a minor test, the kind you do once a week. Other school systems might be different. But "oral exams" sounds fine to me.]
