They should have like an overall rating. Mrs. DeCou is a good teacher, but her class isn't easy, and she doesn't help much. I learned how to do things myself.
She doesn't know what she's teaching and so the whole class is pointless.
If she was a little bit nice and respectful to her students she may get somewhere in her teaching career, and calling the students names doesn't help much !!
You should know the material before attempting to teach it. When I had you, you were learning the things while trying to teach it to us. You make me sick.
