I'd still recommend study as even practicing techs can fail one or both of the exams and end up blowing their money because they take it too lightly. That said, it's mostly pretty straight forward. If you know your way around the inside of your computer, can find the event viewer, and aren't a complete boomer with Windows, you're pretty much good.
That said, take a practice exam and see how you do. Also, if you find reading dry and are more of a visual learner or you just want to take advantage of good, free study options, look up Professor Messer (
