Did you know that you can access over 500 courses from the prestigious Massachusetts Institute of Technology (MIT)? The best part is that it is for free through the MIT OpenCourseWare (OCW).
You have access to lecture notes, assignments, exams and more to anything between Japanese I and Nonlinear Dynamics and Chaos.
I can definitely recommend you to have a look at the mouthwatering selection of physics courses. I did and found more gems than I can shake a stick at.
