CompTIA A+ Exam Overview
What to Expect
The CompTIA A+ (220-1201 1202) exam has 90 questions and a 140-minute time limit. That works out to about 1 minute and 33 seconds per question. You need to score 75% or higher to pass. CompTIA uses a scaled scoring model from 100 to 900. Passing scores vary by exam: Security+ requires 750, Network+ requires 720, and A+ requires 675. Performance-Based Questions are weighted more heavily than standard multiple-choice questions.
Testing and Delivery
CompTIA exams are delivered through Pearson VUE at testing centers and online. Exams often include Performance-Based Questions (PBQs) that simulate real tasks like configuring a firewall or analyzing log output. These PBQs appear at the beginning of the exam.
Certification Renewal
CompTIA certifications are valid for three years. You renew by earning Continuing Education Units (CEUs) through training, teaching, publishing, or passing a higher-level exam. The required CEU count varies by certification level.
CompTIA A+ What the Exam Tests
The CompTIA A+ exam covers 9 domains. The heaviest domain is Operating Systems at 16%, so prioritize your study time there. Understanding how these domains connect to real-world practice is more important than memorizing individual facts.
Operating Systems (16%)
Operating Systems accounts for 16% of questions. While not the heaviest domain, it can make the difference between passing and failing. Don't neglect it.
Security (16%)
Security accounts for 16% of questions. While not the heaviest domain, it can make the difference between passing and failing. Don't neglect it.
Hardware & Network Troubleshooting (16%)
Hardware & Network Troubleshooting accounts for 16% of questions. While not the heaviest domain, it can make the difference between passing and failing. Don't neglect it.
Hardware (14%)
Hardware accounts for 14% of questions. While not the heaviest domain, it can make the difference between passing and failing. Don't neglect it.
Networking (12%)
Networking accounts for 12% of questions. While not the heaviest domain, it can make the difference between passing and failing. Don't neglect it.
Software Troubleshooting (10%)
Software Troubleshooting covers 10% of the exam. It's a lighter domain, but easy points if you've studied it. A targeted review of key concepts should be sufficient.
Mobile Devices (7%)
Mobile Devices covers 7% of the exam. It's a lighter domain, but easy points if you've studied it. A targeted review of key concepts should be sufficient.
Virtualization & Cloud (5%)
Virtualization & Cloud covers 5% of the exam. It's a lighter domain, but easy points if you've studied it. A targeted review of key concepts should be sufficient.
Operational Procedures (4%)
Operational Procedures covers 4% of the exam. It's a lighter domain, but easy points if you've studied it. A targeted review of key concepts should be sufficient.
CompTIA A+ How to Prepare
Study Resources
CompTIA CertMaster is the official study platform with Learn, Labs, and Practice components. Professor Messer's free video series on YouTube is a community favorite. CompTIA exams are vendor-neutral, so you need breadth of knowledge across multiple platforms rather than deep expertise in one.
Preparation Strategy
Start by reviewing the official exam guide to understand exactly what's covered. Allocate your study time proportionally to domain weights: spend the most time on Operating Systems (16%) and work down from there. Most candidates need six to twelve weeks of focused preparation depending on their existing experience.
Hands-On Practice
Reading alone won't get you through this exam. You need hands-on experience with the technology. Set up a lab environment, work through practical scenarios, and practice until the concepts feel natural. The exam tests application of knowledge, not just recall.
CompTIA A+ Exam Day Strategy
Time Management
With 1 minute and 33 seconds per question, pace yourself from the start. Don't spend more than three minutes on any single question during your first pass. Flag uncertain questions and return to them after completing the rest. A wrong answer and a skipped answer score the same, so never leave a question blank.
Reading Questions Carefully
Pay close attention to qualifier words like "most," "best," "least," and "first." These words change the correct answer entirely. Read every option before selecting your answer, even if the first option looks correct. Exam writers intentionally place plausible distractors early in the option list.
CompTIA A+ Difficulty Analysis & Pass Rates
How Hard Is This Exam?
The CompTIA A+ exam requires a passing score of 75%. With 90 questions in 140 minutes, you get about 1 minute and 33 seconds per question. The difficulty depends heavily on your hands-on experience with CompTIA technologies. Candidates with real-world experience typically find it manageable with focused preparation, while those studying purely from books often struggle with the scenario-based questions.
Pass Rate Data
CompTIA doesn't publish official pass rates for the CompTIA A+. Based on community data and training provider surveys, the first-attempt pass rate for most CompTIA professional certifications falls between 55-70%. Candidates who use structured study plans with practice tests consistently perform better than those who rely on reading alone. If you're scoring above 85% on practice tests, you're very likely to pass.
CompTIA A+ How Our Practice Tests Map to This Exam
Each Pruvos practice test for the CompTIA A+ follows the real exam blueprint exactly: 90 questions, 140-minute timer, and questions distributed across all 9 domains using the official exam weights. Operating Systems (16%) gets the most questions, followed by Security (16%).
After each test, your domain-level score breakdown shows exactly where you're strong and where you need more work. Use Test 1 (free) to get your baseline, then work through the remaining tests as you study. Most candidates who consistently score above 85% on Pruvos practice tests pass the real exam on their first attempt.
CompTIA A+ Why Practice Tests Matter
Practice tests are the most reliable predictor of exam readiness. Each practice test here follows the real CompTIA A+ exam format: 90 questions, 140-minute time limit, and questions distributed across all 9 domains according to the official exam weights.
Take your first practice test early in your study process to establish a baseline. Don't wait until you feel "ready" because that moment never comes. Use your scores by domain to identify weak areas, study those areas, then test again. Aim to consistently score above 85% on practice tests before scheduling your real exam.
