The CompTIA A+ pass rate hovers around 55-60% on first attempt. That means nearly half the people who paid $253 per exam voucher walk out empty-handed — not because the material is impossibly hard, but because they studied the wrong things in the wrong order. This guide is built around fixing that.
CompTIA A+ study is different from most cert prep because there are two separate exams: Core 1 (220-1101) and Core 2 (220-1102). You need to pass both to earn the certification. Most failed attempts come from people who cramped both exams into one study block, or who focused on memorizing acronyms instead of understanding how the domains connect to real help desk work.
What CompTIA A+ Study Actually Covers
The A+ is structured around job tasks a Tier 1/Tier 2 support technician does daily. CompTIA publishes the exact exam objectives — reading them before you open any course is the single highest-leverage thing you can do. Here's what each exam tests:
Core 1 (220-1101) — Hardware and Connectivity
- Mobile Devices (15%) — laptops, tablets, smartphones; hardware and OS troubleshooting
- Networking (20%) — TCP/IP, DNS, DHCP, Wi-Fi standards, cable types, basic switch/router config
- Hardware (25%) — CPU types, RAM, storage (HDD, SSD, NVMe), motherboard components, power supplies
- Virtualization and Cloud Computing (11%) — hypervisors, cloud service models, deployment types
- Hardware and Network Troubleshooting (29%) — the biggest domain; systematic diagnosis workflows
Core 2 (220-1102) — OS, Security, and Soft Skills
- Operating Systems (31%) — Windows 10/11 features, macOS, Linux basics, command-line tools
- Security (25%) — malware types, physical security, account management, encryption basics
- Software Troubleshooting (22%) — OS and application issues, browser problems, mobile device troubleshooting
- Operational Procedures (22%) — documentation, change management, safety, environmental impacts
Notice that Troubleshooting domains combine to almost 50% of the total exam weight between both tests. If your CompTIA A+ study plan spends most time on memorizing specs and almost none on systematic diagnosis workflows, you're studying for the wrong exam.
How Long CompTIA A+ Study Takes (Honest Estimate)
CompTIA's official estimate is 9-12 months of "practical experience" or 6 months of dedicated study. That's conservative and assumes part-time commitment. More realistic timelines based on background:
- No IT background: 3-4 months for Core 1, 3-4 months for Core 2. Don't rush — the networking domain alone takes a few weeks to actually internalize.
- Some help desk or PC repair experience: 6-8 weeks per exam is achievable. You're filling gaps, not building from zero.
- Studying for recertification: The 220-1101/1102 objectives are meaningfully updated from the 1001/1002 series. Budget 2-3 weeks per exam to catch the delta (cloud computing, newer Wi-Fi standards, Windows 11 specifics).
A realistic CompTIA A+ study schedule looks like 1.5-2 hours per weekday and 3-4 hours on weekends. Cramming more than that produces diminishing returns — the troubleshooting scenarios require time to actually settle into pattern recognition.
A+ Study Strategy That Works
Do Core 1 First, Then Core 2
Some people try to study both exams simultaneously. Don't. The Core 1 hardware and networking content is foundational context for the Core 2 security and OS topics. Trying to understand drive encryption before understanding storage types is backwards.
Use the Exam Objectives as Your Table of Contents
Download the official CompTIA A+ exam objectives PDF (free from comptia.org). Every objective is a potential exam question category. After each study session, go back to the objectives list and mark what you actually understand versus what you've just read. The gaps between "read it" and "could explain it to someone else" are where exam failures hide.
Do Practice Questions Early, Not Just at the End
Most candidates do a video course, read a textbook, then hit practice tests. Flip it: do a block of practice questions on each domain immediately after studying it. The A+ exam uses performance-based questions (drag-and-drop, simulations) in addition to multiple choice — you need to practice applying knowledge under time pressure, not just recognizing correct answers.
Build a Physical or Virtual Lab
The troubleshooting questions are heavily scenario-based. Reading about how to troubleshoot a POST beep code is much weaker preparation than actually opening a PC and reseating RAM until you get one. For software troubleshooting in Core 2, run Windows 10 and 11 in VirtualBox — it's free, and navigating the OS while it's in front of you is different from reading screenshots.
Top CompTIA A+ Study Courses
CompTIA A+ Core 1 (220-1201) Full Course & Practice Exam
A comprehensive video course covering all Core 1 domains with a built-in practice exam. Rated 9.4/10 on Udemy — the hardware and networking sections are particularly detailed, which matters given those two domains represent 45% of Core 1's exam weight.
CompTIA A+ Core 1 (220-1201) 6 Practice Tests [2026]
Six full-length timed practice exams specifically for Core 1. The value here is question volume — 9.4/10 rated, and the performance-based question simulations give you the closest thing to the real exam experience before test day. Use this alongside a video course, not instead of one.
Once you have A+ in hand, the natural progression paths split toward networking or security. For those heading toward Security+:
CompTIA Security+ (SY0-701) Exam Prep 2026 - For Beginners
Rated 9.5/10. This is the most accessible Security+ prep course for A+ holders — it assumes the foundational networking knowledge A+ covers rather than re-explaining it, so the pacing works well as a continuation of your study path.
CompTIA Security+ (SY0-701) 1,000+ Practice Questions 2026
1,000 practice questions is more than you'll find in most individual prep courses. At 9.5/10, this is worth bookmarking now even if Security+ is 6 months away — the question bank will still be current for the SY0-701 exam objectives.

Common CompTIA A+ Study Mistakes
Studying the Retired Exam Objectives
The 1001/1002 series retired in October 2022. If you find study material that doesn't mention the 220-1101/1102 exam numbers, you're looking at outdated content. The cloud computing domain in particular was significantly expanded in the current version.
Skipping the Operational Procedures Domain
Operational Procedures makes up 22% of Core 2, covers documentation practices, environmental regulations, change management workflow, and safety procedures. Most IT-background candidates dismiss this as "soft" content and under-study it. It's where exam points get left on the table.
Not Taking Timed Practice Exams
Both exams are 90 minutes. Core 1 and Core 2 each have up to 90 questions including performance-based items that take longer. People who've only answered untimed practice questions frequently run out of time on the real exam. At least your final 2-3 practice test sessions should be full timed simulations.
Memorizing Without Understanding
The A+ exam is not a memory test. The scenario-based questions give you a situation and ask what you would do, not what a term means. Memorizing that "RAID 1 is mirroring" doesn't help when the question describes a customer with two drives wanting redundancy and asks which RAID level you recommend and why.
FAQ
How hard is the CompTIA A+ exam?
Moderate. It's not the hardest entry-level cert (Security+ has a steeper curve), but the breadth of topics — hardware, networking, OS, security, troubleshooting — means you can't just learn one area well. The performance-based questions also trip people who've only done multiple-choice prep. With 100+ hours of structured study, most candidates with no prior IT background can pass.
Do I need to take Core 1 and Core 2 in order?
CompTIA doesn't enforce an order — you can take them in any sequence. However, the Core 1 hardware/networking foundation makes Core 2 content easier to understand, especially the OS and security domains. Most study plans recommend Core 1 first.
How much does CompTIA A+ cost?
Each exam voucher costs $253 USD (2026 pricing). You need to pass both exams, so budget at least $506 total. Retake vouchers are available at a discount. CompTIA occasionally offers bundles with CertMaster study tools.
How long is CompTIA A+ valid?
Three years. You can renew by passing a higher-level CompTIA exam, earning 20 Continuing Education Units (CEUs), or completing CompTIA's CertMaster CE course. The certification version you earned stays on your transcript regardless of the current exam version.
Is CompTIA A+ worth it for job hunting?
Yes, specifically for help desk and IT support roles. Many IT support job postings either require or prefer A+, and it's often the baseline credential that gets resumes past automated screening. It won't directly land you a sysadmin or network engineer role, but it's the standard entry ticket for Tier 1/Tier 2 support positions that then lead to those roles.
What jobs can you get with CompTIA A+?
Help desk technician ($40-55K), IT support specialist, desktop support analyst, field service technician. These are starting points — most people use A+ as the first cert in a path toward Network+, Security+, or vendor-specific certs like CCNA or MCSA. The salary jump comes at the second or third certification level, not A+ alone.
Bottom Line
CompTIA A+ study is well-documented territory — there's no shortage of courses, books, and practice tests. The failure rate isn't from lack of materials; it's from poor strategy. Study Core 1 first and fully before moving to Core 2. Weight your time toward the Troubleshooting domains because they make up nearly half the exam. Do timed practice exams starting early, not just as a final check before test day. And don't skip Operational Procedures in Core 2 just because it sounds boring — 22% of the exam disagrees.
If you're starting from scratch, the CompTIA A+ Core 1 Full Course paired with the 6 Practice Tests gives you enough material to pass without overcomplicating the study path. Add Professor Messer's free content for reinforcement on any domain where the paid course feels thin. That combination, plus a physical or virtual lab for hands-on practice, covers the realistic preparation most first-time candidates need.
