Getting Through CompTIA A+ Without Losing Your Mind

The CompTIA A+ exam covers two core tests—Core 1 (220-1101) and Core 2 (220-1102)—and together they test everything from hardware troubleshooting to basic networking, mobile devices, and security fundamentals. It's entry-level by design, but that doesn't mean it's easy to pass on the first attempt. I've watched people breeze through it and I've watched equally smart people fail twice because they studied the wrong material. Here's how I actually approached it. Mike Meyers' books are popular for a reason. They're detailed, they have good diagrams, and the practice questions are close to the real exam format. That said, they run expensive and they cover more than you need—you'll spend time on sections that barely show up on the test. Jason Dion's video courses on Udemy are cheaper and more focused. I paired Dion's videos with Professor Messer's free YouTube series, which walks through every objective line by line. Messer isn't flashy, but he hits every topic the exam actually tests, and he does it in about 40 hours total across both exams. The thing most people miss is that CompTIA publishes the official exam objectives for free on their website. Your study guide should map directly to those objectives, not the other way around. I printed the objectives and literally checked each one off as I went through my materials. Anything not on the list? Skip it. The exam won't ask about it. I wasted two full days studying printer subsystems one year because a book dedicated three chapters to it. The actual exam asked maybe two questions on printers total. That's a real problem I ran into—the syllabus is huge but the exam weightings are uneven. Hardware and troubleshooting carry the most points. Security and soft skills are underrepresented relative to how much reading they require.

How I Actually Studied

I built a schedule that lasted about six weeks for both exams. Week one and two were Core 1 topics: mobile devices, hardware, networking, and hardware troubleshooting. Week three and four shifted to Core 2: operating systems, security, software troubleshooting, and operational procedures. I spent the last two weeks doing practice exams and filling gaps. Practice exams are where most people go wrong. They take them too early, before they've built a foundation, and then they get discouraged by low scores. Or they take them too late and never identify their weak areas. I started taking full timed practice exams after week three—just Core 1 material at that point—and used the results to recalibrate what I needed to revisit. Dion's practice exams are closer to the real thing in terms of question style. Professor Messer's free exams on his site are decent for quick checks but shorter and less representative of the actual exam difficulty. CompTIA's own official practice test is the gold standard if you can afford it, but it's pricey. The format trip-up I keep seeing is the performance-based questions. These are simulators where you actually drag and drop, configure a router, or diagnose a problem in a virtual environment. They show up at the start of the exam and count toward your score just like regular questions, but they don't give you multiple choice to fall back on. I practiced these specifically by using Dion's exam simulator software, which includes PBQs. Without that rehearsal, you'll waste time on the real exam figuring out how the interface works instead of answering questions. Another thing nobody warns you about: you can flag PBQs and come back to them, but flagging doesn't save your work on some of the older simulator versions. Make sure you know the interface before test day.

What Actually Stuck

Rote memorization fails on this exam because the questions are scenario-based. You won't see "What is the pin count on a DB-15 connector?" You'll see "A user reports intermittent display issues on an external monitor connected via VGA. Which of the following should the technician check first?" The answer is usually about signal interference or cable damage, not the connector spec itself. You need to understand the why, not just the what. I kept a running list of things I consistently got wrong and reviewed it daily. Common traps include confusing MAC addresses with IP addresses in troubleshooting scenarios, mixing up RAID levels (RAID 0 vs RAID 1 vs RAID 5 shows up constantly), and underestimating how much PowerShell and command-line knowledge Core 2 expects. netstat, ipconfig /all, nslookup, sfc /scannow—these come up in practical scenarios, not as trivia. Port numbers are another one. Knowing that RDP is 3389 and SSH is 22 is useful, but you also need to know why those ports matter in a security context. Here's a counter-intuitive point: the A+ is increasingly favoring cloud and virtualization concepts over physical hardware. The older editions of study guides leaned heavily into BIOS configuration and physical component replacement. The current exam still tests those, but there's noticeably more emphasis on Azure AD, MDM solutions, and virtual machine management than there was five years ago. If your study guide was published before 2023, treat it as a reference, not a complete picture.

The Downsides

No single Comp Tia A Study Guide covers everything adequately. Meyers is too broad. Dion is good but his practice questions sometimes use outdated terminology. Messer is accurate but dry and lacks depth on the rarer topics. The workaround I used was combining resources: Messer for objectives coverage, Dion for practice exams, and the CompTIA objectives document as my master checklist. It took more effort upfront but cut my total study time from an estimated eight weeks down to six. Another limitation is that the A+ doesn't test practical skills directly—you could memorize every answer and still struggle to actually build a PC or configure a home router. If your goal is job readiness rather than just certification, supplement your study with hands-on labs. I built a cheap rig from used parts and actually broke and fixed it. Troubleshooting a boot failure on real hardware teaches you more than any simulation.

Bottom Line

Pick a primary resource, map it to the official objectives, practice with timed exams early and often, and don't ignore the performance-based questions. Six weeks of focused study is realistic for someone with basic IT familiarity. Less if you already work in the field. More if you're starting from zero. The exam is passable without being brilliant—you just need to know what CompTIA wants to hear, not everything that's technically true.
