way late, but I'm rewatching with your reactions now cuz I didn't watch it till a few months ago.
It's kinda interesting cuz at my school (in America,) absolutely everything would be expected to be straight out of your head from studying the textbooks and notes we took except for one of my teachers who would give us the exact copy of the tests (no answers, we needed to use our notes and textbook to fill it out) 2 days before the test. There was one time he straight up tacked a filled out copy on the board and didn't say a word LMAO. No one figured out it was there.. sadly
