So recent events with my classes have prompted me to look else where in terms of learning (let's just say I have a shitty physics professor). I know about MIT OpenCourseware, anyone know some other good places to basically get a free lecture?

I always feel that many youtube videos are lacking in content; they show the basics but never get on to much harder problems.
