CompTIA A+ Certification: Complete Beginner’s Guide for 2026

CompTIA A+ is the most common first certification for people starting in IT support. It requires passing two exams — Core 1 (220-1201) and Core 2 (220-1202) — covering hardware, mobile devices, networking, operating systems, security, and troubleshooting.

If you want a help desk or desktop support role, A+ is the classic starting point.

Who this guide is for

• Complete beginners in IT
• Students looking for a first IT job
• Career changers from non-tech fields
• Hobbyists who build PCs and want a recognized credential

Core 1 vs Core 2

CompTIA released the 1200 series in 2025. Check that your study material targets this version, not the retired 1100 series.

What A+ teaches you

• Installing and replacing components: RAM, storage, power supplies, displays.
• Configuring SOHO networks, Wi-Fi, and common protocols.
• Supporting Windows, macOS, Linux, iOS, and Android.
• Basic security: malware removal, account policies, encryption, social engineering.
• Professional practice: documentation, change management, safety, and customer communication.

Jobs A+ can lead to

Help desk technician, desktop support, field service technician, and junior system administrator. After A+, many people take Network+ and Security+, or a cloud fundamentals exam like AZ-900.

Cost and value

You pay for two vouchers, so A+ costs more than a single-exam certification. Students often receive academic discounts.

The return is strong because so many entry-level job ads list A+ explicitly.

Core 1 or Core 2 first?

Most people take Core 1 first because hardware and networking build vocabulary for Core 2. If you already support Windows users daily, Core 2 first is fine.

A realistic study plan

The plan below assumes about 8–10 hours a week. Stretch it if you are new to the subject, compress it if you already work with the technology daily.

How to use practice questions the right way

Practice tests are the closest thing to a rehearsal, but only when used properly:

• Use a practice test as a diagnostic first, before deep study, to find your weak domains.
• Review explanations line by line. The learning happens in the review, not in the score.
• Simulate the real exam at least twice: same time limit, no notes, no pausing.
• Retire question sets once you have seen them repeatedly. A rising score on a memorized set is a false signal.
• Book the exam when you score consistently well on fresh questions, not after one lucky run.

Legitimate practice questions are written to mirror the style and objectives of an exam, with explanations that teach the reasoning. Avoid anything that claims to be leaked live exam content: it breaks vendor exam agreements, can get your certification revoked, and leaves you without the skills the job requires.

Choosing the right study resources

Whatever exam you choose, the same resource stack works:

1. Official objectives from the vendor — the definitive list of what can be tested.
2. One primary course or book, current for the exam version.
3. Hands-on practice in a lab, sandbox, or trial environment.
4. Practice questions with explanations to diagnose gaps and build exam stamina.
5. Spaced-repetition flashcards for terms and facts you keep forgetting.
6. A study group or accountability partner to keep momentum.

Avoid buying five courses at once. Depth with one good resource beats skimming many.

A sample weekly study rhythm

A sustainable week for a working professional looks like this:

That is roughly 7–8 hours per week. Adjust the pace, not the pattern: if you have more time, add a second lab block rather than more passive reading.

If you miss a day, do not try to double up — just continue the schedule. Consistency over several weeks matters far more than occasional long sessions.

Build hands-on experience while you study

Hands-on practice is what turns a certificate into a job offer:

• Pick a lab environment for your certification: a cloud free tier, Packet Tracer, a home virtual lab, or a vendor sandbox.
• Build one small project per exam domain and keep notes on what you did and why.
• Troubleshoot on purpose: break something and fix it using logs and documentation.
• Publish a short write-up of your projects on LinkedIn or GitHub; it gives interviewers something concrete to ask about.
• Revisit labs in the final week instead of rereading notes.

Common mistakes to avoid

• Studying for the retired 1100 series
• Reading without ever opening a PC or installing an OS
• Leaving more than a few months between Core 1 and Core 2
• Ignoring operational procedures questions

Check the official exam details first

Certification vendors update exams regularly. Before you buy books or courses, open the official exam page and check three things: the current exam code and version, the skills or objectives document with domain weightings, and any retirement or replacement date.

Use that document as your checklist and tick off each objective as you study and lab it. When your practice material and the official outline disagree, the official outline wins.

Exam-day checklist

• Confirm your ID matches your registration name exactly.
• For online proctoring, run the system test a day early and clear your desk completely.
• Sleep properly the night before; last-minute cramming hurts more than it helps.
• Read each question’s final sentence first so you know what is being asked.
• Flag long questions, answer the quick ones, and return if the exam allows review.
