Angry and confused
I'd found out that I (along with about 80% of the class) wasn't properly doing the reading assignments my history class has been giving out, so I'm going to have to redo them (read: take detailed notes on about 70 pages of content) before the test on Tuesday.
The teacher in that class also refused to go over the material from the previous night's reading, saying that the in-class content should only be review from the previous night's reading and we should already have the content described in our notes before coming to class.
The whole scene just came across to me as "My class is moving at my pace, and if you can't keep up, you can go forget yourself", and it put me in a bad mood for pretty much the rest of the morning.
Additionally, I completely flunked a vocabulary test in German today, making that two out of three total tests so far that I've done poorly on for that class.
