Physics-
http://www.courses.dce.harvard.edu/~physe1b/
Chem isn't up yet. We used Chang's "General Chemistry".
My advice for the two classes since I'm in a caffeinated mood
Physics - read the chapter before lecture, do the problems that are within the chapter as you read to get an introduction to the types of problems, go to lecture, go to section, do the homework problems, do end of chapter problems as needed for review
Chemistry - I'm an ******* so I never read the textbook so go lecture, do the practice problems, watch/attend the friday review, do the friday review problems, do the homework problems, attend section. The key is doing the practice problems on your own prior to section. I also had success doing the friday review problems on my own before watching the video
