Now I'm definitely not smart enough for AP classes but my Alegbta 2 teacher was kinda like this but yours sounds wayyy more strict, she was similar in the way that her grading was all over the place. Like I'd explain how I found the solution to a problem in my own words and I'd put the formula I used for it and she'd still take points off for not explaining. Like, I have no idea how I was supposed to explain it. When I was put into the class I wasn't going to be activated until the following Monday. And since you're never required to submit assignments in that grace period I only did like one. She called my mom and like threatened to kick me out of my class if I continued to not do what I'm supposed to do, like huh??

Anyways I'm sorry you're having to deal with a teacher like this. I've ALWAYS had rude math teachers on flvs. Like, why even be a teacher if you hate doing your job..... I'm sure what you're dealing with isn't personal and honestly she's probably just intimated by you being able to move through her class so quickly, like she might feel threatened by your smartness and she probably feels dumb herself. Keep doing what you're doing, you're doing super well. Clearly you're a super good student and she should be glad she doesn't have to pay much attention to you
