All About Circuits?

Anyone ever work through this online textbook?

I have been studying on it some. My head hurts.

I haven’t but I am slowly trying to worth through this:

It’s pretty awesome. Lots of lectures, free online text, homework, tests, discussion forum, etc. It’s totally free and you even get a certificate if you pass the class. Too late for this semester if you’re signing up now but there’s nothing stopping you from going through the course just to learn.

Thanks Randy!

Taking a peek at the the MITx course - looks like some superb tools for learning there. Thanks for sharing randy909!
