I am worried I will fail my math course this semester because the professor has very unusual rules. She says that we must do our homework, check each problem to see if it's correct, and then leave space after it if it's wrong and we can't figure out how to get the right answer. She will then go over the problems in class, and we're supposed to write the work she shows us and the correct answer into the space we've left. If EVERY SINGLE PROBLEM does not have a correct answer with work shown (whether hers or our own) by the end of the semester, she says she will absolutely fail us.
She also says that if every single problem is not written out in the format she desires, she will fail us.
I know I can go to a tutor to find out how to do any given problem, but her demands seem unreasonable because:
1. She doesn't get to every problem in class.
2. She's once or twice arrived at a different answer from the book (I discovered after class) and she wants us to write her answers down, but never gets around to going back over those problems to find out why she got a different answer from the book.
3. She does not answer her emails.
4. She tells us to come to office hours but is never there during her office hours even if emailed beforehand.
5. She leaves IMMEDIATELY after every class, saying she has somewhere important to be.
She also yelled at me and marked me partially absent when I had to use the restroom during class.
Is all this reasonable? Am I just being a whiner? She doesn't seem to like me, and I'm worried she'll purposely look for some little flaw in my homework and fail me.
