CompTIA A+ (Core 1)

The Certilum bank for the CompTIA A+ (Core 1) holds 90 Foundation questions across 5 exam domains. Every question ships with a written explanation of why the right answer is right, and each row exists in three wording variants, so a session never repeats itself verbatim.

The real CompTIA exam is timed at around 90 minutes, with a passing score of 75%. The Certilum diagnostic mirrors that structure so your practice session feels like test day.

We measured 90 questions and scored them 1-10 on a composite of format difficulty: multi-select questions (which require every correct option), scenario-length questions, interactive code questions and explanation depth. The CompTIA A+ (Core 1) scores 2.0 out of 10, with a per-domain breakdown on the difficulty page.
