I've been working on putting together MIT and various other college's open courseware resources together into a coherent and logical format so J. Random Hacker can teach herself or fill in his gaps in whatever he took in college. I know a little bit about prereqs and organizing courses--my day job is writing software to do that--but most of the engineering stuff is out of my area of expertise. Its got a long way to go, however, there are currently links up to most of UCI's chemistry online courses including a biochem course and MIT's bio and bio-engineering courses. This might be of interest to diybiocincy. If you do end up going through any of the video courses, it would be awesome to add some content related to it under that page to try and fill it out. I'm working through Tensor Calculus, Relativity, Quantum Theory, and the front matter from Pirsa, but I have a way to go before I can comment intelligently on those courses. I will say that MIT's quantum course is neat and well organized(8.04). So far, Drexel's Tensor Calculus course is clear and coherent but probably will require you to watch the calc, diff eq, and linear algebra videos first.
