About 30% of first-time A+ test-takers don't pass—not because the material is impossible, but because they studied the wrong things in the wrong order. Most people over-index on video courses and under-invest in performance-based question practice, which is exactly where the exam trips people up. This CompTIA A+ study guide skips the generic advice and focuses on what actually moves the needle.
What CompTIA A+ Study Actually Requires
The A+ is two separate exams: Core 1 (220-1201) and Core 2 (220-1202). You need to pass both to earn the certification. Each costs around $246–$253 USD, so you're looking at roughly $500 just in exam fees before a single course purchase. That's a real reason to take preparation seriously rather than winging it.
Core 1 covers hardware, networking fundamentals, mobile devices, virtualization, and cloud basics. Core 2 covers operating systems (Windows, macOS, Linux, Chrome OS), security, operational procedures, and software troubleshooting. Each exam gives you 90 minutes for up to 90 questions. The passing score is 675 for Core 1 and 700 for Core 2, on a 100–900 scale.
The questions break down into two types: multiple-choice (including multiple-select) and performance-based items (PBQs). PBQs are drag-and-drop, simulated command-line, or scenario-based interfaces. They appear at the start of the exam and take far longer per question than standard multiple choice. Many candidates spend 20+ minutes on PBQs and then rush through the rest. Plan for that.
Build a CompTIA A+ Study Plan Before You Open a Single Course
The official CompTIA exam objectives document is free to download from CompTIA's site. Print it. Every domain, every sub-topic, every objective is listed—this is your syllabus, not any course's table of contents.
Core 1 domains and their exam weights:
- Mobile Devices – 15%
- Networking – 20%
- Hardware – 25%
- Virtualization and Cloud Computing – 11%
- Hardware and Network Troubleshooting – 29%
Core 2 domains and their exam weights:
- Operating Systems – 31%
- Security – 25%
- Software Troubleshooting – 22%
- Operational Procedures – 22%
Hardware and Network Troubleshooting is the single biggest chunk of Core 1. Operating Systems is the biggest piece of Core 2. If your study time is limited, weight it accordingly. A lot of people spend equal time on every domain and then get caught out on the high-weight topics under pressure.
A realistic A+ study timeline for someone new to IT is 10–14 weeks at roughly 1–2 hours per day. If you have a helpdesk or hardware background already, cut that in half. Don't let a rigid "3-month plan" from a random study guide force you into padding topics you already know.
The Core Study Stack: What to Actually Use
You don't need every resource. You need three things: a structured video course to build foundational understanding, a solid textbook or notes resource for reference, and a high-volume practice test bank for exam simulation. Most people buy too much and use too little.
Video Course
A good video course walks you through each exam objective systematically and shows hardware components visually—helpful if you haven't physically handled RAM sticks or SATA drives. Watch at 1.25–1.5x speed on topics you're comfortable with. Slow down on command-line tools, troubleshooting methodology, and anything that shows screen simulations of tools like Device Manager or ipconfig.
Take notes by hand or in a plain text file—not just passive watching. If you can't explain a concept out loud after the segment ends, you didn't learn it yet.
Practice Exams
Start taking practice exams earlier than feels comfortable, ideally after your first pass through each domain rather than waiting until the end. The goal isn't to score well early—it's to identify gaps while you still have time to address them.
A score of 80%+ on multiple practice exams from different question banks is a reasonable readiness indicator. Don't rely on a single test bank; questions repeat across vendors and you can memorize answers without understanding the material. Use at least two different sources.
Review every wrong answer—not just the ones where you had no idea, but especially the ones you got wrong despite being confident. Those are the dangerous blind spots.
Hands-On Practice
Command-line tools show up in both PBQs and standard questions. You should be able to use ipconfig, ping, tracert, netstat, sfc /scannow, chkdsk, diskpart, and tasklist without looking them up. Boot a Windows VM, open a command prompt, and run these until they're automatic. This is not optional if you want to handle PBQs efficiently under time pressure.
For hardware, YouTube teardown videos are genuinely useful if you don't have physical machines to work with. Watching someone reseat RAM, identify POST beep codes, or replace a laptop LCD is better than reading a description of the process.
Top Courses for CompTIA A+ Study
These are the highest-rated options currently available for the 220-1201/1202 exam series.
CompTIA A+ Core 1 (220-1201) Full Course & Practice Exam
A comprehensive video-based course covering every Core 1 objective with included practice exam questions. Solid choice for your primary study vehicle if you prefer structured, instructor-led content over reading.
CompTIA A+ Core 1 (220-1201) 6 Practice Tests [2026]
Six full-length practice exams mapped to the 220-1201 objectives—useful specifically for volume drilling and identifying weak domains before exam day. Pair this with the full course above rather than using it as a standalone resource.
CompTIA Security+ (SY0-701) Exam Prep 2026
Not an A+ course, but relevant if you're planning your certification path: Security+ is the most common next step after A+, and early exposure to security concepts covered in Core 2 (malware types, authentication, encryption basics) can reinforce your A+ prep while giving you a head start on the next cert.
CompTIA Security+ (SY0-701) 1,000+ Practice Questions 2026
Another forward-looking resource—A+ Core 2 has a 25% security domain that overlaps meaningfully with Security+ fundamentals. If you're treating A+ as a steppingstone to Security+, cross-referencing these questions can deepen your understanding of the security material in Core 2.
Common CompTIA A+ Study Mistakes
These show up repeatedly among people who fail on the first attempt:
- Watching without doing. Passive video consumption doesn't build retrieval. You need to close the video and recall the concept from memory to actually retain it.
- Skipping the PBQ format. If you've never interacted with a simulated drag-and-drop interface or a command-line PBQ, the exam isn't the time to figure out the mechanics. Look for courses or free demos that show the PBQ format specifically.
- Over-studying the easy domains. Most people are relatively comfortable with basic hardware from everyday use. Don't spend three weeks on RAM types when you're still fuzzy on subnetting or Windows troubleshooting tools.
- Using outdated materials. The 220-1101/1102 and 220-1201/1202 objectives are different. If a course doesn't explicitly cover the current exam version you're registering for, check the objective list manually before purchasing.
- Not scheduling the exam. People who set a concrete exam date study more consistently than those who study "until they feel ready." Pick a date, pay for the voucher, and let the deadline do its job.
FAQ
How long should I study for the CompTIA A+?
Most people with no prior IT background need 10–14 weeks at 1–2 hours per day. If you've worked in IT support, even informally, 4–6 weeks of focused prep is often enough. The variable isn't the material—it's how much hands-on context you're bringing in. Don't benchmark yourself against someone else's timeline.
Should I take Core 1 or Core 2 first?
CompTIA doesn't require a specific order, but Core 1 is generally taken first. The hardware and networking fundamentals in Core 1 provide context that makes Core 2's OS and security content easier to absorb. Study them sequentially, not simultaneously—splitting your focus across both at once is inefficient for most people.
Are practice tests enough to pass, or do I need a full course?
Practice tests alone are not enough if you don't already have a strong IT foundation. Without conceptual understanding, you'll memorize answer patterns rather than learn the material—which fails you on PBQs and novel question phrasing. Use a structured course to build the foundation, then use practice exams to test and reinforce it.
How hard is the CompTIA A+ compared to other IT certifications?
It's appropriately difficult for an entry-level credential—broader than it is deep. The challenge isn't any single topic being extremely technical; it's the sheer breadth of domains covered across two exams. People with helpdesk or hardware experience often find it manageable. People studying from scratch sometimes underestimate the scope until they hit the practice exams.
Can I pass the CompTIA A+ without hands-on experience?
Yes, but you need to compensate deliberately. Use virtual labs, run command-line tools in a Windows VM, and watch hardware teardown videos to build the mental models that experience would otherwise provide. The exam includes scenario-based questions and PBQs that reward practical intuition—pure book knowledge has a ceiling.
What's the best free resource for CompTIA A+ study?
The official CompTIA exam objectives document is the most underused free resource—it tells you exactly what the exam tests. Beyond that, Professor Messer's A+ course notes and free study groups are widely cited as solid supplementary material. Free resources work best as supplements, not as your primary study vehicle when $500 in exam fees is on the line.
Bottom Line
Effective CompTIA A+ study comes down to three things: knowing exactly what's on the exam (use the official objectives), building real understanding through a structured course rather than passive watching, and stress-testing that knowledge with high-volume practice exams before you sit for the real thing. The people who fail usually cut corners on one of those three.
Start with the Core 1 full course and its paired practice tests to get your footing on the 220-1201 objectives. Once you're consistently hitting 80%+ on timed practice exams, schedule the actual exam—waiting for "perfect" readiness is usually procrastination in disguise. Core 2 follows the same playbook with heavier emphasis on Windows troubleshooting and security fundamentals.
The A+ is a real credential that opens helpdesk and IT support roles, but it's a starting point, not a destination. Build your study habits now, because Security+ and beyond will demand the same disciplined approach.
