has a bigger attitude than most students, is not pretty but clearly cares about her looks too much so mean to kids who dont get it (dont ask questions in her class-not worth it) least favorite teacher

Not special, but being a Math teacher, she doesn't need to be. Helpful and intelligent.

Doesn't know her subject very well. She can't explain things when I ask her..shouldn't be teaching advanced if she can't even explain the stuff!! UGH!!

Garbage. Quite possibly the worst math teacher ive ever had at CSH, which has a very strong math department. Completely useless.

Can be an alright person, but never wants to. She always gives attitude and hands out detentions like its her job instead of math! By the way, nice lexis.

Her tests and quizs are easy but 4 days out the 5 days of the week she is in a bad mood and takes it out on the class. She gives alot of detetions too.
