Frequently asked questions

How many questions are on the A+ exams?

Each core has a maximum of 90 questions in 90 minutes, including performance-based questions. You must pass both cores to earn the A+ certification.

What scores do I need to pass A+?

Core 1 (220-1101) requires 675/900 and Core 2 (220-1102) requires 700/900. The two exams are booked and taken separately.

Which core should I take first?

Most people take Core 1 first — it's the order CompTIA presents them and Core 2's troubleshooting content builds on Core 1's hardware foundation. There's no rule though; take them in whichever order fits your study plan.

Are these real A+ exam questions?

No — they're original questions written to the 220-1101/1102 objectives at exam-level difficulty, with explanations. Braindumps violate CompTIA policy and can void your certification.

Is this a free A+ exam practice test?

Yes — the sample questions on this page are free with no account, split between Core 1 (220-1101) and Core 2 (220-1102). A free account adds a full 25-question diagnostic per core, a readiness score, and 20 practice questions a day.
