I read something in todays local paper about this. I'm not sure if it's been posted in the past or not, but I know there are a lot of people here still in school (at some level) or planning to go, thought this might be worth a look:

Schools that take part in this will post assignments, (sometimes) notes, exams, and materials needed for an individual to take themselves through the respected courses. I've briefly looked through a couple of these and seems to be pretty nice. A good way to give yourself more practice on a particular subject or a preview of what you could see in the future. The only cost I can see associated with this is finding the textbook a course is using and either buy it or check it out from a library. As well as any equipment that might be needed. Just thought I'd throw this out there.
