Course description

CompTIA creates IT certifications that cover topics such as how to build and fix computers or how to secure businesses from internal and external threats. Every major IT manufacturer is part of CompTIA. The CompTIA A+ certification is a popular entry point for people looking to work in IT. The certification requires you to pass two exams, the Core 1 (220-1101) and Core 2 (220-1102), but requires no experience or study (though, as Mike points out, study is good!)
