CompTIA A+ is two exams — Core 1 (220-1101) and Core 2 (220-1102) — covering hardware, networking, mobile devices, operating systems, security, and troubleshooting. The breadth is wide, and the domain weights are uneven: some domains carry nearly twice the exam weight of others. Choosing a practice test that tracks your performance per domain is critical when you have nine domains across two exams to manage.
Here are the five best CompTIA A+ practice test resources in 2026.

1. Courseiva — Best free A+ practice test (most complete option)
Courseiva's CompTIA A+ practice test covers all domains across both Core 1 and Core 2 — Hardware, Networking, Mobile Devices, Virtualization, Operating Systems, Security, Software Troubleshooting, Hardware Troubleshooting, and Operational Procedures — with questions weighted to match the official blueprint.
Here is what distinguishes it from every other free option:
Exam Readiness Score
Managing nine domains across two exams without a readiness signal is how candidates overprepare on areas they already know and show up weak in others. Courseiva's Exam Readiness Score tracks your accuracy, coverage, and weak-area trends per exam so you know when each one is genuinely ready to sit.
Domain Proficiency Tracking
Troubleshooting carries 29% of Core 1 and 26% of Core 2 — the highest-weighted domain in each exam. Your domain proficiency dashboard shows your accuracy per domain after every session. If your Hardware Troubleshooting score is 58% but your Networking Concepts score is 84%, you know exactly where tomorrow's session should focus.
Per-Domain Practice Sessions
From the A+ domains hub, drill any domain in isolation: 10, 20, 30, or 50 questions. Troubleshooting in isolation — working through scenario questions on display issues, storage failures, network connectivity — builds the applied judgment A+ demands much faster than random mixed drilling.
Adaptive Practice & Weakest-Target Mode
Adaptive practice adjusts sessions based on your performance history. Weakest-target mode specifically routes sessions toward your lowest-scoring domains and question types. For A+, this often targets hardware troubleshooting scenarios, OS commands, and security procedures — the applied, scenario-based content that catches most candidates off guard.
Timed Practice & Mock Exams
Each A+ exam has a 90-minute time limit. Timed practice builds the speed and accuracy you need under those conditions. Full A+ mock exams run at 30, 60, or 90 questions. Take a 90-question timed mock in the final week for each exam to confirm readiness.
Crash Mode
Two exams, nine domains, and a lot of applied content. Crash Mode pulls your missed questions, bookmarks, and weakest-domain content into one compressed session — the most efficient use of the 48 hours before each exam date.
Missed Questions Review, Bookmarks & Performance Analytics
Every incorrect answer is saved to Missed Questions Review automatically. Bookmark the scenario questions you find ambiguous. Your performance dashboard shows accuracy trends and domain performance so you can see whether your preparation is actually progressing.
Flashcards & Daily Practice
A+ flashcards cover port numbers, cable types, connector types, OS commands, and troubleshooting steps — the quick-recall content both exams test. Quick 10 and the Daily Challenge keep practice consistent across the longer A+ study timeline.
Verdict: The most complete free A+ practice platform covering both exams. Start here.
2. Professor Messer — Best free video + question combo
Professor Messer offers free A+ video training and sells a practice exam bundle for ~$35. The questions are solid and align well with his videos.
Pros: Free video content. Affordable practice exams. Questions feel realistic. Cons: No domain proficiency tracking. No adaptive practice. Smaller question pool.
Verdict: Strong value if you are watching his video training. Pair with Courseiva for volume and tracking.
3. Boson ExSim-Max — Best paid A+ simulation
Boson ExSim-Max for A+ includes 600+ questions across both exams with detailed explanations and realistic exam simulation.
Pros: Extremely realistic. High quality explanations. Timed exam mode. Cons: ~$109. No domain-only filtering. No adaptive practice.
Verdict: Best paid simulation for the final two weeks of preparation.
4. Dion Training — Affordable video-aligned practice
Jason Dion's A+ practice tests on Udemy are well-regarded and align with his popular video courses.
Pros: Affordable (~$15–20). Good question quality. All domains covered. Cons: No adaptive practice or readiness tracking. Explanation depth varies.
Verdict: A solid affordable addition if you are using his video course. Not a replacement for systematic domain tracking.
5. Mike Meyers — Video-first learners
Mike Meyers' Udemy A+ course includes practice questions and is a popular choice for video-first learners.
Pros: Engaging video instruction. Questions match the exam's applied style. Cons: Practice questions are supplementary to the video course, not the main product.
Verdict: Good if you prefer his teaching style. Pair with Courseiva for domain tracking.
How to use Courseiva for A+ prep
Core 1 weeks 1–3: One domain per week. Use the A+ domains hub to drill 20–30 domain-specific questions per session. Prioritise Troubleshooting (29%) and Networking (20%) first.
Core 1 week 4: Mixed adaptive sessions. Check domain proficiency dashboard. Use weakest-target mode for trailing domains. Take a 90-question mock exam.
Repeat for Core 2: Prioritise OS (25%) and Security (25%) first. Use the same domain-drilling approach.
Frequently asked questions
How hard is CompTIA A+? The breadth of A+ makes it challenging. Nine domains across two exams with applied troubleshooting scenarios catch candidates who study too narrowly. Domain proficiency tracking prevents that.
What is the A+ passing score? Core 1: 675 out of 900. Core 2: 700 out of 900. Aim for 80%+ on practice tests.
Is Courseiva's A+ practice test free? Yes — all questions are free. A free account unlocks Exam Readiness Score, domain proficiency tracking, adaptive sessions, and full analytics.
Verdict
Courseiva for free daily practice across both exams with full domain tracking. Professor Messer for free video content. Boson ExSim-Max for a paid final simulation in the last two weeks.
