How to Study for the CompTIA A+ Exam

To study for the CompTIA A+ you need to pass two exams, Core 1 (220-1201) and Core 2 (220-1202), each up to 90 questions in 90 minutes with a mix of multiple choice and performance-based task simulations. The fastest way to prepare is a mix of three things: read or watch a course that covers every domain, do hands-on practice with real or virtual hardware, and drill practice questions until you can answer them cold. Most candidates spend 6 to 12 weeks depending on prior IT experience, and the people who pass are usually the ones who tested themselves relentlessly instead of just rereading a study guide.

How long does it take to study for the CompTIA A+?

Plan for roughly 6 to 12 weeks. If you already work in IT support, fix computers as a hobby, or know your way around a command line, you can be ready faster, sometimes in a month of focused study. If the A+ is your first exposure to hardware, networking, and operating systems, give yourself the full twelve weeks and study a little every day rather than cramming on weekends. A realistic schedule is one domain per week for reading and labs, then two to three weeks at the end for full practice exams and cleaning up weak spots. Because the certification is two separate exams, many people study for Core 1, sit it, then start on Core 2, which spreads the load and gives you a win partway through.

What is on the CompTIA A+ exam?

The A+ (V15) splits its content across two exams that you must both pass. Core 1 leans toward physical hardware, networking, and troubleshooting, while Core 2 covers operating systems, security, and the softer skills of the job like documentation and safety. Each exam is scored on a scale of 100 to 900. Core 1 passes at 675 and Core 2 passes at 700. The table below shows every domain and its weight so you know where to spend your hours.

Both exams include performance-based questions, which drop you into a simulated task like configuring a device, sorting steps in the correct order, or matching connectors to ports. These usually appear at the start and carry more weight than a single multiple choice item, so do not let them eat your clock.

Do you have to study for both A+ exams?

Yes. You need to pass Core 1 and Core 2 to earn the certification, and passing only one does not get you the credential. The good news is you can take them separately and in either order. Most people prepare for one exam at a time, schedule it, then move on to the other, which keeps each study block focused. There is overlap in the mindset the two exams reward (careful troubleshooting, knowing the correct order of steps), but the content is distinct, so budget real study time for both rather than assuming Core 2 will come free after Core 1.

What is the best way to study for the CompTIA A+?

The best method combines a full course, hands-on labs, and heavy practice testing. Reading or watching a course gives you coverage of every objective. Hands-on work makes the knowledge stick because A+ is a practical exam: build or open a PC, install an operating system, set up a small network, configure a phone's email. Then practice questions turn that knowledge into recall you can produce under time pressure. This last part matters most. Rereading a chapter feels productive but fades fast, while answering questions forces your brain to retrieve the answer, which is what you will do on exam day. That is the core idea behind active recall and testing yourself. Work a batch of A+ practice test questions after each domain, mark what you miss, and go back to those topics before moving on.

How to study for the hardest domains

Three domains trip up the most people: troubleshooting, security, and operating systems. Each rewards a slightly different approach.

1. Troubleshooting. This is the biggest slice of Core 1 at 28%, and questions test process, not trivia. Memorize the CompTIA troubleshooting methodology (identify the problem, establish a theory, test it, and so on) and practice applying it to scenarios. When a practice question describes a symptom, name the most likely cause and the next step before you look at the options.
2. Security. Core 2 devotes 28% to security, covering malware, social engineering, authentication, and how to secure workstations and mobile devices. Make flashcards for the attack types and controls, because the wording of the answer choices is where people slip.
3. Operating systems. Also 28% of Core 2. Get comfortable with Windows features, common command line utilities, and installation and configuration steps. Actually type the commands on a real or virtual machine so you remember what each one does instead of just recognizing the name.

For all three, the pattern is the same: understand the process, then quiz yourself on realistic scenarios until the correct step is automatic.

How many practice questions should you do before the exam?

There is no magic number, but a useful target is several hundred questions per exam, done in rounds until you consistently score above the pass mark with room to spare. Aim to be answering full sets in the high 80s or better on Core 1 and Core 2 practice sets before you book the real thing. More important than the raw count is what you do with your misses: every wrong answer points to a topic you have not learned yet, so keep a running list and re-drill it. Take at least two or three full-length timed practice exams so 90 questions in 90 minutes feels normal. A focused CompTIA A+ practice test is the most efficient way to build that bank and see your weak domains at a glance.

Is the CompTIA A+ hard?

The A+ is challenging but very passable with steady preparation. It is broad rather than deep: you have to know a little about a lot, from power supplies to phishing to Linux commands, and that breadth is what makes it feel hard. The performance-based questions add pressure because they expect you to do a task, not just recognize a fact. People who struggle usually underestimate the hands-on side or skip practice exams. People who pass treat it like a driving test, learning the material and then rehearsing the exact conditions of the day until it is routine. Because it is two exams, the workload is real, but each one is beatable on its own.

How to turn your own A+ notes into practice questions

Your own notes are the best raw material for practice questions because they match how you organized the material. Instead of writing quiz questions by hand, upload your notes, a study guide chapter, or exam-objective PDFs and let an AI build the questions for you. An AI MCQ maker turns a page of notes into a/b/c/d questions in seconds, so you can drill a domain right after you study it. If you want questions that mimic the format of a real certification, a certification exam generator produces exam-style sets from the same source material. If your notes are handwritten or scanned, run them through an OCR tool first so the text is machine-readable, then generate your quiz. Trainers who write A+ study guides can also repurpose that material into search-friendly articles with an AI SEO content tool.

Put it together

Study one domain at a time, get your hands on real or virtual gear, and turn every study session into a self-test. Start with a CompTIA A+ practice test after each topic, keep a list of what you miss, and finish with full timed rounds until both Core 1 and Core 2 feel routine. Once you pass, the natural next step is a Network+ practice test to deepen the networking knowledge the A+ introduced. Learn the objectives, then rehearse them, and the exam becomes a formality.
