Most “free” practice tests aren’t really free. You click through, answer two questions, and then a wall pops up asking for your email, a credit card, or a “free trial” that quietly renews. When you’re trying to gauge whether you’re ready for A+, Network+, or Security+, that friction is the last thing you need.
The six resources below skip all of that. Every one lets you start answering real exam-style questions right away, without creating an account. Open a tab, pick a domain, and see where you stand.
What to look for in a practice test
Before the list, a quick word on what actually makes a practice test worth your time. Question volume matters less than you’d think. What you want is coverage across every exam domain, answer explanations that tell you why a choice is right, and questions written against the current exam version. CompTIA rotates its exams every few years (Security+ is on SY0-701, Network+ on N10-009, A+ on the 220-1201/1202 Core series), so anything built for a retired version will teach you outdated material.
Use these tests two ways: as a diagnostic early on to find your weak domains, and as a timed rehearsal near the end to build pacing and stamina.
1. CareerEmployer
CareerEmployer is the easiest place to start if you want exam-realistic questions with no barrier in front of them. The CompTIA Security+ practice test walks you through scenario-based questions across all five Security+ domains, with explanations attached so you learn from every miss rather than just seeing a score. If you’re heading toward the infrastructure track instead, the CompTIA Network+ practice test covers the same ground for N10-009.
Both open directly in the browser with nothing to install and no email required. It’s a strong first stop when you want to size up where you stand before committing hours to a study plan.
2. ExamCompass
ExamCompass is a long-running favorite in the CompTIA community, and for good reason. Its practice tests are organized by exam domain, so you can drill the exact area you’re weak in rather than grinding through mixed sets. Every test is free with no registration or email, and each one ends with a score report that lists your answers alongside the correct ones.
It’s plain in design and heavy on multiple-choice, so it won’t simulate performance-based questions. But for straight knowledge reinforcement, the domain-by-domain structure is hard to beat.
3. Test-Guide.com
Test-Guide.com offers multiple free CompTIA exams with no registration and detailed answer explanations. Beyond the questions themselves, the site does a solid job of explaining the exam mechanics: passing scores, the 900-point scaled scoring system, retake wait periods, and what each certification actually gets you.
That context is genuinely useful for a first-timer who isn’t sure how the CompTIA scoring works. Use it as both a question bank and a quick primer on how the exams are structured.
4. ExamPremium
ExamPremium runs one of the larger free question banks around, with thousands of questions spanning A+, Network+, Security+, and beyond. There’s no registration or email wall, and answers come with explanations.
The trade-off with a bank this big is that quality varies from question to question, and the interface is dated. Treat it as volume practice rather than a polished exam simulator. When you’ve exhausted the tighter, more curated sets and just want more reps, this is where you turn.
5. SecuSpark
SecuSpark leans into a modern, offline-first design: questions load locally in your browser, so you can practice on a plane or in a coffee shop with no connection. You can jump straight into a test with no account, no credit card, and no trial period. The free tier includes several full practice exams per certification across Security+, A+, Network+, and a couple of the higher-level tracks like CySA+ and PenTest+.
Creating an account unlocks extras like progress tracking and a gamified study mode, but that’s entirely optional. The core practice experience is available cold.
6. CompTIA Practice Test (comptiapracticetest.net)
This one keeps things focused on the big three: A+ (Core 1 and Core 2), Network+, and Security+. Questions are written to feel like the real thing, with clear wording, realistic scenarios, and explanations for every answer.
The site also pushes good study habits, encouraging you to keep an error log, retest weak areas, and simulate the full 90-minute window as your exam date approaches. It’s a clean, no-nonsense option when you want to concentrate on the most in-demand certifications without distraction.
How to actually use these tests
Free questions only help if you use them deliberately. A few habits that make the difference:
- Diagnose first. Take one full test cold, before you’ve studied much, and note which domains you bomb. That’s your study map.
- Read every explanation, especially on questions you got right. A lucky guess is a gap you haven’t found yet.
- Keep an error log. Write down what you missed and revisit it a few days later. Retesting the same weak spots is where real improvement happens.
- Simulate the real thing near the end. Sit for a timed, full-length test in one session. The exam is as much about pacing and endurance as it is about knowledge.
- Don’t ignore performance-based questions. Most free tests are multiple-choice only, but the real exams open with hands-on PBQs. Practice those separately using CompTIA’s official labs or a simulator that includes them.
The bottom line
You don’t need to hand over your email or your card to find out whether you’re ready. Start with a diagnostic on one of these sites today, find your weak domains, and build your study plan around what you actually miss. When you want scenario-based questions with explanations and zero friction, CareerEmployer’s Security+ and Network+ tests are a fast, no-sign-up place to begin.
Practice tests reflect current exam objectives as of 2026. Always confirm you’re studying for the active exam version (Security+ SY0-701, Network+ N10-009, A+ 220-1201/1202) before you dig in.
