I need help for psych

Ok, so I am on a block schedule school, so I take half my classes first semester and the other half second semester. I took ap psychology first semester and my teacher was terrible, I ended up with a 93 in there but I don’t remember anything from there. I really feel like if I took the exam right now I would get maybe a 2. Please anyone suggest me videos, websites, apps, anything that could actually teach me the material rather than quiz me on it
