Preparatory Math Course: All the other weeks I was too lazy to write

I don't really remember anything from the second trig except that I'm kinda cooked. This was followed by two weeks of complex numbers which were actually identical and were only repeated because the first one was during holidays. Complex numbers were kinda boring. Not as boring as what came next though: combinatorics. Literally the most trivial shit. I remember people were leaving in droves. Then there were some planimetrics, which I don't remember anything about again. Then I skipped one. Then stereometry, which made me ask myself:

"is high school math actually that simple? am I just that simple?"
