My history teacher doesnt teach AT ALL?

Okay so I'm in the 8th grade and I just finished the history part of the CST. I don't think I did so well because my teacher didnt review with us at all. Okay so all my teacher does is give us the answer to everything for example. One day before any test she would give us all the answers and she allows us to use notes on the test. Shes INCREDIBLY lazy. (This is her first year teaching history but she has being teaching language arts for about 10 years) So instead of reviewing for the history part of the cst she makes us watch a movie. And she even told us that she wont review with us and that we should search up the released questions online. My friend also told me that If we dont do well on the cst we have to take this extra reading helping program in high school! It's not my fault I didnt do so well on the cst, its that she doesnt teach at all! All she does is assign us questions and she just goes and plays music/ go on fb on her computer!! So if i fail do i HAVE to take that reading helping program????
