math teacher

     Won't name any names but my math teacher is bad. On Mondays he has a 'homework day' where he doesn't teach anything and just pairs random kids up to work on the homework even if both kids aren't done you aren't allowed to work together one person has to help the other no matter what. Kinda stupid but whatever. Then on Wednesdays he has his lecture days where he finds all the mistakes he did in the notes, there's a lot, and goes slow as all hell and only gets through like half of the notes if we're lucky. So not only does he not know his own notes he doesn't know his homework either. He makes the homework significantly harder than the notes that he doesn't get all the way through. So on homework days when students ask questions from the homework he does it on the board and get confused on his own problem and waste half the class time just doing this one problem instead of helping all the other students who need help. He doesn't solve the problem doing anything we learned but instead uses calc which nobody in this class knows and just says the answer. Why teach the class if you can't do the problems using things we learned in the class.
