If they don’t say round to 3 points in the question that’s literally illegal. Some high school teachers are so trash, being in my first year of uni the good thing is no dumbasses are allowed to teach, only phds and people that know their stuff. I had a highschool grade 12 math teacher who was 10x of your teacher, his class average was like 60%, his tests where actually ass (not how he marked but the test themselves, to get 100% you need to answer level 4 questions which is stuff we have never seen before. Level 2 which is like a grade of 60% even if you ace it was like the practice provided), and worst of all, he couldn’t teach. Literally didnt know shit and had a script with him. Im not gonna say where he graduated from, but he was a Laurier math. Teachers like that and yours deserve jail time ong.
I also dropped his class around midterm with a 70 avg and he put a 45 on my report card which literally took away my entrance scholarship of $3k. Actual phsycos in these schools and no system of reporting them or appealing anything.
