CompTIA A+ Practice Test Guide: How to Use Practice Exams to Prepare

A CompTIA A+ practice test is most valuable when you use it to find weak spots, not to memorize answers. Take one early as a diagnostic, use domain scores to steer your study, and save full timed exams for the final two weeks.

This guide explains a practice-test routine for both Core 1 and Core 2.

Who this guide is for

• A+ candidates preparing for Core 1 or Core 2
• Learners who score well on quizzes but worry about the real exam
• Instructors designing practice routines
• Self-study candidates without a classroom

What a good A+ practice test looks like

• Questions mapped to the current 220-1201/220-1202 objectives.
• Clear explanations for every option, with references to the objective.
• A mix of multiple choice and performance-based tasks.
• Domain-level scoring so you can see where you are weak.
• A large enough bank that you see fresh questions, not repeats.

A four-stage practice routine

1. Diagnostic (week 1): one untimed test. Do not worry about the score.
2. Domain drills (weeks 2–6): 20–30 questions on the domain you studied that week.
3. Mixed sets (weeks 7–8): 50 questions across all domains, timed.
4. Full simulations (final week): 90 questions in 90 minutes, no notes.

How to review a practice test

Spend twice as long reviewing as testing. For every miss, write the objective number, why your answer was wrong, and why the correct one is right.

Revisit the topic in your notes or lab the same day.

Performance-based question practice

PBQs on A+ can include configuring a SOHO router, matching ports to protocols, ordering troubleshooting steps, or using command-line tools. Practise them in a VM and with interactive simulations; they carry significant weight.

Where to find practice questions

Use CompTIA’s official CertMaster Practice, reputable course providers, and our CompTIA practice questions, which focus on explanations rather than memorization.

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

• Retaking the same test until the score looks good
• Skipping explanations for correct answers
• Never practising under time pressure
• Ignoring PBQs because they are harder to find

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

• Arrive (or log in) at least 15–30 minutes early.
• Skim your one-page summary of weak topics, then put it away.
• Watch for qualifiers like best, first, most cost-effective, and least effort.
• Eliminate clearly wrong answers before choosing between the last two.
• Keep an eye on the clock at the quarter, half, and three-quarter marks.

Frequently asked questions

What score should I aim for on A+ practice tests?

Consistently 85% or higher on questions you have not seen before.

How many practice tests should I take?

Quality matters more than number; most people need one diagnostic, weekly drills, and two or three full exams.

Are practice tests the same as the real exam?

No. Good practice tests mirror the style and objectives, not the actual questions.

Should I use practice tests for both Core 1 and Core 2?

Yes, each exam has its own objectives and needs its own practice.

Work through the official objectives, build hands-on experience, then use timed practice questions to measure your readiness and review every explanation.
