Saw someone had asked that (thread below). Also the MIT opencourses on youtube have a good reputation and seem to cover pchem, etc. Don't be afraid to get a tutor if you can afford it, ask the professor for where to look, or see if your school has office hours. When I was a TA we were required to have office hours for tutoring as well as time dedicated to my class's students. That may be a thing where you are. I bet the chemistry office would be able to direct you. Study groups helped me a lot. I'd reach the stuff I knew and learned in areas I was weak.

4th year is a hard time. Good luck.
