I had a high school math teacher who was threatening (come to find out my dad had him and my dad broke a 3 sided ruler on the teachers head). I also had a bully teacher in grad school. I responded to them like the bullies they were and claimed my power... and got thrown out of grad school...hmmm.... The math teacher, well the other teachers found out (I was a teachers pet with several) MAN did the put him in his place!
My advice would be to within your limits (you don't want to wreck your Sr year over them) don't let it be a secret. Make it as public as you SAFELY can that this is going on. Let other teachers know, administers, anyone who will listen and support you,
