The real exam, the right study order, and the one rule that tells you you're ready. No fluff.
First, who's talking. I'm Mike Meyers. I've been writing the McGraw-Hill All-in-One A+ guides and teaching this since 1995 — long enough to know the A+ isn't hard because you're not smart enough. It's hard because most people study the wrong things in the wrong order. This plan fixes that.
The A+ is the front door to IT — the cert that proves you can actually do the job, not just talk about it. It assumes roughly a year of hands-on experience (don't panic if you don't have it — that's what studying is for). And here's the part nobody tells first-timers: the A+ is two exams. You're not certified until you pass both.
You can take them in either order, but take them one at a time. Nobody sits both in one day.
Each exam is up to 90 questions in 90 minutes, a mix of multiple choice and performance-based questions (PBQs — where you do a task: put steps in order, match cables to connectors). Scored 100–900; you pass at 675 — which, as I like to say: Gee, Mr. Obvious — you can get a few questions wrong and still pass. You don't have to be perfect.

When you're consistently scoring 85% or higher on practice tests, schedule the exam. Not before — you'll just rattle yourself. Not way after — you'll go stale. 85% is the green light. And remember: you can miss a handful and still pass.
Your voucher is the exam fee — you redeem it at Pearson VUE (CompTIA's testing partner) to book. You choose a test center (bring two forms of ID) or online-proctored from home (clear the room, government-ID scan, give yourself ~15 extra minutes for setup). The hand-off to Pearson is normal — that's just where CompTIA exams are booked.
A+ gets you in the door. The well-worn next step is Network+ (prove you can connect the box to everything else), then Security+ — the CompTIA trifecta, and where the better-paying jobs start looking. One rung at a time.
Read it, drill it til it's boring, walk in ready. And when you pass — because you will — let us be the first to congratulate you on your A+. — Mike
