CompTIA A+ Core 2 (220-1202): Operating Systems and Security
If you are staring down the CompTIA A+ Core 2 (220-1202) exam, your real question is probably simple: how do I pass A+ Core 2 without wasting weeks on the wrong material? This post lays out exactly what the exam measures, how the time works against you, and where a mock test genuinely helps, so you can build a study plan around the parts that actually earn points.
What the Core 2 exam actually is
Core 2 is the second of the two exams that together earn the CompTIA A+ credential. It leans toward the software side of IT support: operating systems, security, troubleshooting, and the day-to-day procedures a technician follows. If you already sat Core 1, the format will feel familiar, but the content is different enough that you cannot coast on hardware knowledge here. This topic pairs well with CompTIA A+ Core 1 (220-1201): What the Exam Covers.
You get 90 questions and 90 minutes. That works out to roughly 60 seconds per question. It sounds generous until you hit a scenario question that wants you to read a short situation, weigh four plausible options, and commit. The exam is delivered linearly, so pacing discipline matters: fall behind early and you will be rushing the back third, which is precisely where fatigue costs you marks.
Scoring runs on a scaled range from 100 to 900, and you need 700 to pass. That scale is not a simple percentage, so do not assume "70 percent right" equals a pass. Aim comfortably clear of the line in your CompTIA A+ Core 2 mock test attempts rather than scraping it.
The four domains and their weights
Core 2 splits into four domains, and their weighting tells you where to spend your hours. Operating Systems and Security are tied for the largest share, so those two deserve the bulk of your preparation. Software Troubleshooting and Operational Procedures are smaller but far from trivial. For practical tips on this, see Cisco CyberOps Associate (200-201) vs CompTIA Security+.
A free CompTIA A+ Core 2 study plan can turn those domain weights into a week-by-week schedule that fits your available hours.
| Domain | Weight |
|---|---|
| Operating Systems | 28% |
| Security | 28% |
| Software Troubleshooting | 23% |
| Operational Procedures | 21% |
Because Operating Systems and Security each carry 28 percent, more than half your score rides on those two areas combined. If your time is limited, that is where to start. But do not write off Operational Procedures at 21 percent, since it covers documentation, safety, and communication topics that many hands-on technicians underestimate and then lose easy marks on.
What this mock contains
Here is the honest part. The real A+ Core 2 exam includes performance-based questions, which are interactive tasks rather than multiple choice. This mock is multiple-choice and multiple-response only. It covers every domain at its official weighting and matches the real question count and timing, but you will not practise the interactive interface here. Your scaled score is our estimate: CompTIA weights performance-based questions more heavily than multiple choice and does not publish that weighting, so treat the number as a guide, not a guarantee.
That limitation is worth stating plainly because it changes how you should use the tool. A good practise exam for IT support here is best for drilling recall, sharpening your reasoning on scenarios, and rehearsing pace. Pair it with hands-on lab work for the performance-based tasks, and you cover both halves of the real thing. Want to go further?

How to use a mock test well
Sit the full 90-question set under real timing at least twice before your exam date. The first run exposes weak domains; the second confirms whether your fixes stuck. After each attempt, sort your misses by domain and compare them against the weighting table. A cluster of errors in Security, at 28 percent, hurts far more than the same number in Operational Procedures.
After you review your domain misses, a free CompTIA A+ Core 2 readiness check can confirm which topic to prioritise next.
Once you are consistently clearing 700-equivalent scores with time to spare, you are ready. If you want the volume of questions that makes that possible, you can buy a mock test pack and work through fresh sets rather than memorising a single one.
Final word
Stop guessing whether you are prepared — timed CompTIA A+ Core 2 practice exams tell you objectively.
