Everything You Need to Pass Your CompTIA Exam

Free, unlimited practice for Security+, A+, and Network+ — built to match the real exam experience.

Blueprint-Weighted Distribution

Questions are drawn proportionally from each exam domain — exactly matching official CompTIA objectives. No domain is over or under represented.

Realistic PBQ Labs

Interactive Performance-Based Questions appear first in every mock. Drag-and-drop, fill-in, and config sims with partial credit scoring — identical to the real exam format.

Scaled Scoring 100-900

Scores use the exact same scale as CompTIA. Each mock shows your estimated scaled score and pass/fail verdict, with domain-level breakdowns to target weak areas.

Timed Exam Conditions

Full 90-minute timer matching real exam pressure. PBQs count down separately. Flag questions to review later — just like the real testing interface.

Detailed Explanations

Every answer includes a thorough explanation addressing why the correct option is right AND why each distractor is wrong. Reference links to official exam objectives.

6 Unique Mock Exams

Six seeded mock exams per certification. Each mock draws from different question pools — take them all without repetition. Quick drill and speed challenge modes are included.

Frequently Asked Questions

How many questions are on each CompTIA exam?
Security+ SY0-701, A+ Core 1 (220-1201), and Network+ N10-009 each have up to 90 questions including 3-7 performance-based questions (PBQs). CompTIA uses a scaled scoring system (100-900) with a passing score of 750 for Security+, 675 for A+ Core 1, and 720 for Network+.
Are these practice tests really free?
Yes — all mock exams, domain practice, and PBQ labs across all three certifications are 100% free. No registration, no credit card, no paywall. We believe quality exam preparation should be accessible to everyone.
How do your mock exams compare to the real CompTIA tests?
Our mocks are blueprint-weighted — questions are distributed proportionally across exam domains matching official CompTIA objectives. PBQs appear first in each mock (exactly like the real exam), and we use the same 100-900 scaled scoring. Questions are scenario-based and match the difficulty level of the actual certification exams.
What are PBQs and why are they important?
Performance-Based Questions (PBQs) are interactive simulation labs that appear at the very start of every CompTIA exam. They test hands-on skills — configuring firewalls, analyzing logs, subnetting, troubleshooting hardware — and carry 2× to 2.5× the weight of multiple-choice questions. Our PBQ library has interactive drag-and-drop labs with partial credit scoring.
Can I use these on mobile?
Yes — the entire platform is fully responsive on smartphones and tablets, including drag-and-drop PBQ labs. Your progress is automatically saved in your browser so you can resume later from any device.
