Would like help with A+ ect

I am a PC tech kinda happened into my job am looking for resources for testing I am without much money. Therefore classes and such will be next to impossible. I am primary wage earner with three kids. And the wage is just enough to make it most weeks. If anyone has some Free resources for studying or OLD books they would be willing to donate for studying the basics of A+ and MSCE ect. HELP would be greatly appreciated most of the books I have found are very expensive for me to afford and classes are impossible to find in my remote location nearest college is about 100 miles away.
