CompTIA A+ Practice Quiz (20 Questions)

If you’re working toward CompTIA A+, the fastest way to improve is to stop “studying everything” and start finding exactly what you miss. This quiz is built like a mini-diagnostic: short, focused, and designed to sharpen your fundamentals for real-world IT support.

You’ll get 20 questions across core A+ topics, and a clear results summary at the end that shows your score, what you missed, and why the correct answers are correct. That means every attempt turns into a tighter, smarter study plan.
