I am beginning a program to teach Computer Repair and Networking for Job Corps. I would like to find some free/cheap web resources for teaching this program. I have googled A+, but not found anything free. What I use doesn't need to be A+ specific, I just need some PC repair information for my students to review.
Your suggestions are greatly appreciated!
