I'm trying to get into the computer repair/tech support field, but it's hard finding stuff without a degree. I'm 24 and have above-average knowledge of computers (can take apart and rebuild a computer, basic troubleshooting for networking and OS issues), but I've come to a halt on my education and am about 3-4 classes short of an associates - I don't have time or money to finish right now.
Lots of jobs asks for certifications, and A+ is a popular and standard one. Any tips on how to prepare for this outside of classes? I found an A+ Certification for Dummies book for $20 and may invest in that, but if there are any free tools online (practice tests, preferably) that anyone knows about, let me know
