What Actually Gets You Through the A+ on the First Try
I spent about three weeks preparing for my A+ certs using mostly free resources, and I passed both 220-1101 and 220-1102. The exam isn't easy, but it's not some impossible gauntlet either. Most people fail because they underestimate the performance-based questions or they rely exclusively on one type of study material and then get blindsided when the real exam looks different. Let me walk you through how I actually approached this, including some stuff that isn't obvious from reading a bunch of Reddit threads.
Free Comptia A Exam
First off, there's no such thing as a completely free exam. CompTIA charges around $246 for each exam attempt when you buy it direct. What IS free are the study materials. Professor Messer has a full course on YouTube that covers both exams. It's thorough, well-organized by domain, and completely free. I went through his entire 1101 and 1102 playlists twice. Once for first exposure, once for reinforcement before I scheduled the test. The official CompTIA website also publishes the exam objectives. This is critical. You need to know exactly what topics are on the test. Everything outside those objectives is bonus material that might help but won't be tested. I found people wasting hours studying printer troubleshooting configurations that aren't actually on the 220-1102 objectives. Don't do that.
Performance-Based Questions Are Where People Lose Points
The PBQs make up about 15% of each exam and they're the section most people complain about. These are simulation-style questions where you drag and drop answers, sequence steps, or configure a virtual device. They don't look like multiple choice at all. Here's what I learned the hard way: the practice PBQs you find online are usually not representative of the actual exam difficulty. Some free ones are too simple, others are overly complicated with extra decoy steps that waste your time. I found that the PBQs on Professor Messer's practice exams are closer to the real thing, but even those undersell it slightly. My workaround was to search for "CompTIA A+ performance based question examples" and then go through whatever screenshots or video walkthroughs people had posted after their own exams. These aren't official, but they show you the interface and the general format. When you sit the real exam, you'll have about 20-25 minutes total across all PBQs, and you can flag them for review. Don't skip them entirely hoping to come back later — that's a common mistake. Do them first while your brain is fresh, then tackle the multiple choice.

What Study Materials Actually Matter
Beyond Professor Messer, the second thing I used was the Sybex A+ study guide. It's not free, but you can find used copies for under fifteen dollars, or access the ebook through some library systems. The Sybex book has practice questions at the end of each chapter that are noticeably harder than the actual exam, which is good because it means when you see something easier on test day, you're prepared. The questions also explain why wrong answers are wrong, which is more valuable than just knowing the right answer. I also used free flashcard decks on Anki. There are shared decks for A+ that people update regularly. The spaced repetition system means you'll see the cards you struggle with more often without realizing it. I spent about two weeks doing 20-30 flashcards a day while watching Professor Messer's videos in the background. Double immersion works better than you'd think. For hands-on practice, you don't need expensive equipment. A virtual machine with VirtualBox is fine for most scenarios. Set up Windows 10, Windows 11, and a Linux distro. Practice going into Device Manager, troubleshooting driver conflicts, using PowerShell commands, and configuring network settings. The exam asks you to identify hardware issues and choose the right tool, so familiarity with the tools matters more than memorizing facts.
The Domain Breakdown That Actually Helps
220-1101 covers hardware and virtualization. The biggest domains by question count are mobile devices, networking, and hardware. Hardware is where most beginners stumble because they've never actually opened a PC tower or identified RAM types by sight. Download the CompTIA A+ hardware troubleshooting checklist and print it out. Look at actual images of motherboards, CPUs, RAM slots, and power supply connectors. When I took the exam, I saw a question showing a motherboard with missing components and I had to identify what was wrong. If you've never looked at a real motherboard, that question is a guess. 220-1102 covers operating systems, security, and software troubleshooting. The OS domain is huge. Know Windows 10 and 11 inside and out — registry edits, Group Policy, PowerShell commands, BitLocker, Windows Update configurations. Security is equally important and it's gotten heavier on recent exam versions. You need to understand encryption methods, port numbers, protocols, and security best practices for both desktop and mobile. Port numbers especially — you'll get questions asking which port a service uses, and the options will include common ones like 443, 3389, 22, 80, 21, and less common ones like 389, 636, 514. Memorize the common ones and recognize the patterns for the rest.
What I Wish I'd Known Before Starting
One thing nobody tells you: the exam is longer than it feels. Both exams give you 90 minutes for up to 90 questions, but the PBQs eat into that time. I had about 75 minutes left for multiple choice after finishing the simulations, and I was surprised by how rushed I felt near the end. Practice timing yourself. Do a full practice exam with a timer and see where you actually stand. Most people finish their first timed practice with 20 minutes to spare and get cocky. Then the real exam hits and every question takes longer than expected. Another thing: don't study the same way every day. Mix it up. Watch videos one day, do practice questions the next, build a VM and troubleshoot it the day after. Your brain retains information better when you switch contexts. I caught myself going through Professor Messer's videos passively on day three and absorbing almost nothing. Once I started actively pausing and asking myself "what would I do here?" the retention improved dramatically.
Common Mistakes That Cost People Points
The biggest mistake I see is overconfidence on the security section. People think they know security because they've heard terms like "phishing" and "malware" their whole lives. But the exam asks very specific technical questions. What's the difference between symmetric and asymmetric encryption? Which protocol uses port 636? What does RADIUS do that TACACS+ doesn't? These aren't common knowledge. They're memorization-heavy and you need to know the specifics. Another mistake is ignoring the troubleshooting methodology. CompTIA loves to test whether you follow a logical process. The answer choices will include things like "replace the component immediately" or "reinstall the driver without checking connections first." The right answer is almost always the methodical one — identify the problem, gather information, establish a theory, test the theory, create a plan, implement, verify, and document. If an answer choice skips steps or jumps to conclusions, it's wrong even if the final action seems reasonable.
How to Know You're Ready
Scores on practice exams aren't perfectly predictive, but they're close enough. If you're consistently scoring 80% or higher on full practice tests that include PBQs, you're probably ready. The real exam tends to be slightly harder than most third-party practice tests, so a 75% on practice exams might still translate to a pass. Below 70% and I'd recommend another week of study before scheduling. Also consider whether you're confident on the weak domains. I was strong on hardware but weak on security. I spent an extra week going through the security objectives repeatedly and doing targeted practice questions on ports, protocols, and encryption. That weak spot would have been a disaster on exam day if I'd walked in unprepared. The whole process from zero to certified took me about six weeks working part-time on evenings and weekends. If you can dedicate more time, it compresses. If you're working full-time and studying casually, it stretches. Neither extreme guarantees failure or success — it's more about consistency and focusing on the right material. Good luck with it.
