I've written a free study guide for the tech exam, see
www.w8bbs.com. It's been used for classes as well as individuals. It's only 12 pages, 8,000 words, but it answers every question in the question pool. I've heard of no one that has read the study guide and failed their exam.
Also, I'm working on an expanded illustrated version of the tech study guide (a comic book perhaps), and need a ham artist (illustrator) to collaborate, e-mail me if interested.
Also, I'm working on a study guide for the general exam, and will accept free help.
