MIT Opencourseware for exam prep

MIT (and several other universities) have put most of their courses online. The Sloan School's opencourseware is very helpful while preparing for exams and solving homework. Pre-exam days are too short and there is hardly any patience to study from the textbook (not to mention a typical 9 hour workday) and anything as concise is just invaluable.

These courses provide slideshows of class notes with excellent explanations of the fundamentals. Although not so indepth as to score an A+, but good enough to recollect everything covered in past weeks of class time.
