There’s a lot of content about CompTIA A+ exams out there. As a self taught software dev turned tech writer and editor (also starting my moonlighting journey as freelance cyber security specialist), I’ve reached a point where the thoughts “I should really get certified” pops into my head.
While I did come out of University with a major in information systems and started parts of my CCNA certifications (but didn’t quite finish it…which is another story for another day) — that stuff is more than a decade ago.
Technology has moved on and while I know a lot of things, it’s still good to formalize it.
After some digging around, here’s a study guide (initially made for myself but decided to share) that might just help you achieve what you’re after — that is, passing the ComTIA A+ exam.
