Ap psychology fucking sucks

I literally hate ap psychology so much. When I walk into the class I start to get irritated because our teacher literally sucks. He doesn’t teach us shit, guys we are on UNIT 3 I am so confused. He doesn’t follow what college board tells him to do and I’m very scared that I’ll be unprepared and fail the AP exam. Does anyone know if there are free online classes I can take to prep for the exam? Or anything that can actually help me pass? pls help…
