The Complete Guide to Passing CompTIA A+ and Landing Your First IT Job

The CompTIA A+ is the single best on-ramp into the IT industry. It’s vendor-neutral, assumes no prior experience, and shows up by name on thousands of entry-level job postings. If you want to break into tech support, desktop support, or help desk work — and use that as a launchpad into networking, security, or cloud — A+ is where almost everyone starts.

But passing the exam is only half the battle. Plenty of people get certified and then stall, unsure how to convert three letters on a résumé into an actual paycheck. This guide covers both halves: exactly how to pass A+, and exactly how to land the job afterward. It’s long because it’s complete. Bookmark it and work through it in order.

This is the deep dive on A+ specifically. For how A+ fits into the bigger picture alongside Network+ and Security+, see my overview of the CompTIA trifecta.

Part 1 — Understand What You’re Signing Up For

A+ is unusual among certs: it’s two separate exams, and you need to pass both to earn the certification. The current version (V15) launched in March 2025.

Both exams are scored on a 100–900 scale, and both mix multiple-choice questions with performance-based questions (PBQs) — interactive simulations where you configure a setting, sort items, or troubleshoot a scenario. PBQs appear first, carry the most weight, and are where most people lose time.

A practical note on logistics: you can take the exams in either order and on separate days — most people do Core 1 first, pass it, then study for Core 2. You don’t have to do them both at once. Vouchers are bought through CompTIA, and you sit the exam either at a Pearson VUE testing center or via online proctoring from home.

Part 2 — What’s Actually on the Exam

CompTIA publishes a free exam objectives PDF for each exam — it is the literal blueprint, and every question maps to a bullet on it. Download both from the official A+ page and treat them as your master checklist. Here’s how the weight breaks down.

Core 1 (220-1201) domains

Notice that troubleshooting and hardware together are over half the exam. Core 1 is the “physical” exam — what’s inside the box, how devices connect, and how to diagnose when they don’t work.

What to prioritize:

• Networking (23%) — memorize common ports cold: 20/21 FTP, 22 SSH, 23 Telnet, 25 SMTP, 53 DNS, 80 HTTP, 443 HTTPS, 3389 RDP, 67/68 DHCP, 143 IMAP, 110 POP3. Know the difference between TCP and UDP, IPv4 vs IPv6, and basic cabling (Cat 5e/6, fiber vs copper).
• Hardware (25%) — RAM types (DDR4/DDR5), storage (SSD vs HDD, NVMe, RAID 0/1/5/10), connectors and cables, power supplies, and printer types.
• Troubleshooting (28%) — this is really about method, which I’ll cover below.

Core 2 (220-1202) domains

Core 2 is the “logical” exam — operating systems, security, and the soft/process skills that real support work demands.

What to prioritize:

• Operating Systems (28%) — Windows is heavily tested: editions, the Control Panel vs Settings, command-line tools (ipconfig, ping, chkdsk, sfc, gpupdate), file systems (NTFS, exFAT, FAT32), plus macOS and Linux basics.
• Security (28%) — malware types and removal, social engineering, authentication, encryption basics, securing workstations and mobile devices. This domain previews everything you’d later go deeper on in Security+.
• Operational Procedures (21%) — safety, documentation, change management, communication, and professionalism. Easy points if you read them; easy to skip and lose.

The one framework to memorize: the troubleshooting methodology

If you learn nothing else perfectly, learn CompTIA’s six-step troubleshooting methodology. It appears directly on the exam and underpins dozens of scenario questions:

1. Identify the problem (gather information, question the user, back up before making changes).
2. Establish a theory of probable cause (question the obvious first).
3. Test the theory to determine the cause.
4. Establish a plan of action and implement the solution.
5. Verify full system functionality and implement preventive measures.
6. Document findings, actions, and outcomes.

When a question shows a technician skipping a step — jumping to a fix without identifying the problem, or failing to back up data first — the correct answer is almost always the step they skipped.

Part 3 — A Study Plan That Actually Works

A realistic timeline for someone studying part-time around a job is 8–12 weeks total — roughly 4–6 weeks per exam. Here’s the system.

Resources (you don’t need to spend a fortune)

• Professor Messer — free, complete video courses for both A+ exams. For many people this is genuinely enough to pass on its own. Start here.
• A good book — Mike Meyers’ All-in-One A+ guide is the classic for depth and hands-on labs.
• Practice exams — this is the one thing worth paying for. Jason Dion’s practice tests (on Udemy) are the community favorite. They train exam stamina and expose your weak domains.
• The official objectives PDFs — your checklist, free from CompTIA.

How to study (not just what)

1. Watch/read by domain, in order. Follow the objectives list top to bottom so nothing slips through.
2. Make active recall your default. Flashcards (Anki) for ports, acronyms, RAID levels, and command-line tools. Passive re-watching doesn’t stick; testing yourself does.
3. Get hands-on. A+ rewards people who’ve touched the hardware. Open up an old PC, swap RAM, build a cheap home lab, install Windows and a Linux distro in VirtualBox, poke around the BIOS/UEFI. Concepts you’ve physically done are nearly impossible to forget.
4. Drill PBQs. Because they come first and weigh the most, practice the interactive style specifically — configuring a SOHO router, sorting RAM types, walking a troubleshooting scenario.
5. Hit 90% on fresh practice exams before you book. Not memorized questions — new ones. When you’re consistently clearing 90%, you’re ready.

A sample 10-week schedule

• Weeks 1–4: Core 1 — one domain block at a time, daily flashcards, weekend lab time.
• Week 5: Core 1 practice exams to 90%, then book and pass Core 1.
• Weeks 6–9: Core 2 — same rhythm.
• Week 10: Core 2 practice exams to 90%, then book and pass Core 2. You’re A+ certified.

Part 4 — Exam Day

• Register through CompTIA and pick your delivery: a Pearson VUE test center or online proctored at home. Online proctoring means a clean desk, a webcam, a room scan, and no interruptions — read the requirements in advance so nothing disqualifies you.
• Triage the PBQs. They’re first and heavy, but if one stalls you, flag it and move on. Bank the fast multiple-choice points, then circle back. Don’t let one simulation eat 20 minutes up front.
• Manage the clock. 90 questions in 90 minutes is about a minute each. Flag anything you’re unsure of and keep moving; you can review at the end.
• Use elimination. CompTIA loves “choose the BEST” questions where two answers are plausible. Rule out the clearly wrong ones, then pick the one that follows correct procedure (often the methodical, safety-first choice).
• You’ll get your pass/fail score immediately at the end. Pass both, and the credential is yours.

Part 5 — Turning A+ Into a Paycheck

This is the part most guides skip, and it’s the part that actually changes your life. A+ qualifies you for real, hireable roles. Here’s how to land one.

The roles you’re now qualified for

Figures vary widely by region and employer; these reflect 2026 listings aggregated from sources like Coursera, ZipRecruiter, and Glassdoor. The pattern that matters: most people advance to higher-paying roles within 2–3 years. Help desk is the on-ramp, not the destination.

Build experience before you’re hired

The classic catch-22 — “needs experience to get experience” — is beatable. You manufacture experience:

• Build a home lab. A cheap second-hand PC, a couple of VMs, an old router. Set up Active Directory, a file share, a simple network. This is real, demonstrable skill.
• Fix real things. Friends, family, a local nonprofit, a small business — offer to troubleshoot their machines, set up their Wi-Fi, remove malware. It all counts.
• Document everything. Write up what you did — a blog, a GitHub repo, a simple portfolio. “Built a home Active Directory lab and documented the setup” is a real talking point that beats an empty résumé.

Write a résumé that gets past the filter

• Put A+ at the top, near your name and in your summary. Recruiters and applicant-tracking systems search for it literally.
• Lead with troubleshooting and customer service. Entry IT is 50% technical, 50% people. Past retail, food service, or any customer-facing job is a genuine asset — frame it as communication and problem-solving under pressure.
• Use real, specific bullets. Not “good with computers.” Instead: “Diagnosed and resolved hardware and OS issues across 15+ personal and volunteer machines using the CompTIA troubleshooting methodology.”
• List your home lab and tools — Windows, basic networking, ticketing concepts, remote support.

Where to actually apply

• Managed Service Providers (MSPs) — they hire entry techs constantly and you’ll learn fast across many clients.
• IT staffing agencies — TEKsystems, Robert Half Technology, Insight Global place enormous numbers of help desk and desktop roles. Get in their system.
• Help desk roles at any larger organization — hospitals, universities, government, and big companies all run internal help desks.
• Search the exact titles from the table above on LinkedIn and Indeed, and set up alerts. Optimize your LinkedIn headline with “CompTIA A+ Certified | IT Support” so recruiters find you.

Nail the interview

Entry IT interviews are predictable. Prepare for:

• “Walk me through how you’d troubleshoot a computer that won’t turn on.” This is your moment to use the six-step methodology out loud. Identify, theorize, test, plan, verify, document. Showing structured thinking matters more than the exact fix.
• Customer-service scenarios — “A frustrated user calls…” Stay calm, empathize, communicate clearly. They’re testing temperament as much as knowledge.
• Basic technical recall — ports, the difference between an IP and a MAC address, what you’d check first for no internet. Your A+ studying has you covered.
• “Tell me about a problem you solved.” Use a real home-lab or repair story, structured as situation → action → result.

Dress one notch above the role, be genuinely enthusiastic about learning, and make it obvious you’ll be easy to work with. At this level, coachability and attitude win jobs.

Part 6 — What Comes After A+

A+ gets your foot in the door; the certs after it raise your ceiling. Once you’re working a help desk or support role, the natural next moves are:

• Network+ — go deeper on networking and open doors to network technician/administrator roles.
• Security+ — the most career-defining next step; it satisfies the U.S. DoD 8140 baseline and is the gateway into cybersecurity.

From there you can branch into cloud (AWS, Azure), systems administration, or security — but it all stands on the foundation A+ gives you. See the full trifecta guide for how to stack them.

The bottom line

A+ is achievable for a motivated beginner in a few months, and it genuinely opens doors. The people who succeed aren’t the ones with the most natural talent — they’re the ones who study the objectives methodically, get hands-on, and then treat the job hunt as seriously as the exam. Pass both exams, build a little real experience, present yourself well, and you can be drawing an IT paycheck this year. Then keep climbing.
