5 major universities offer free online courses in Electrical Engineering, including MIT, Berkley, Utah State, etc.
I haven't much time at the moment, but I did take a gander at the Berkley digital electronic courses. These courses are available in MP3, Webcast, etc. Here is the link if you're interested...
They're real, the MIT ones are at least, they're putting all their lectures online. And yes, prerequisites still apply if you hope to understand the material!
RF is the worst for math, but normal EE classes aren't so bad, especially not the DC stuff.
The courses are for real. If you want official CREDIT (as needed for a degree) you have to enroll (and pay) but if the information is for self study etc have at it. I have referred to some course content occasionally to check stuff I am a bit rusty with. Most of it is great.
