My good friend Craig Hotovy just showed me a web site worth your investigation. MIT Open Courseware
This site has thousands of links to the documentation of selected MIT courses. In the same vein as making AU handout available, MIT has provided us all with the links to understanding Physics, Architecture, Engineering, Electronics, Manufacturing and more. The funny down side to the site is that there is an overwhelming amount of information. My advice is to really focus on a single course at a time and try teaming up with a senior person in your office to help you learn more about why you are drafting what you are. Used effectively, this web site might just help you advance a little faster than before.
Good luck and study hard.
