CompTIA A+ Practice Tests

Ten questions for each core in CompTIA's own wording, with an answer key but no explanations. Core 2 has its own page, linked from CompTIA's Core 2 exam page.

Great fit if you want to see CompTIA's question style for each core before paying for anything.

Poor fit if you need volume, explanations or a timed full-length run; use EasyPrep or Messer.

Topic quizzes for all nine domains across both cores, plus timed 90-question practice exams. Every answer comes with an explanation, and there are iOS and Android apps.

Great fit if you want free, explained practice for both cores that also works on your phone.

Poor fit if you need PBQ practice or an official-style exam; add Crucial Exams or Messer.

Short online tests, 22 for Core 1 and 34 for Core 2, plus quizzes by topic and for acronyms. A score report at the end lists your responses.

Great fit if you want unlimited free checks on terms, ports and acronyms for each core.

Poor fit if you need exam-style wording, PBQs or a timed full run; use Messer or Crucial Exams.

Three 90-question exams per core with multiple-choice questions, some PBQs and a reason for each answer. It is a PDF, so you time and score yourself. Candidates call its wording the closest to CompTIA's.

Great fit if you use Messer's free videos and want exam-like wording and some PBQ practice at a low price.

Poor fit if you want auto-timed, auto-scored tests or more than 270 questions per core; add Dion's exams.

Six timed 90-question exams per core with detailed feedback and a score by domain. All multiple choice, so no PBQs. Candidates call the questions wordier and harder than the real exam.

Great fit if you want many timed, full-length questions with feedback and can handle harder wording.

Poor fit if you need PBQ practice or wording close to the real exam; add Messer or Crucial Exams.

A bank of 1,000 questions per core with flashcards and PBQs, 12 for Core 1 and 7 for Core 2. One plan covers every IT exam on the site. Candidates call its PBQs basic but useful.

Great fit if you want PBQ practice and a large bank for both cores in one plan.

Poor fit if you want a one-time exam pack; Messer's $30 PDFs or Dion's $20 courses cost less.

Quizzes and mock exams in an app and on the web, with 567 Core 1 and 563 Core 2 questions. It has explanations, progress by subject and a weakest-subject mode.

Great fit if you study in short sessions on your phone and want a big bank to drill by subject.

Poor fit if you want a one-time purchase or PBQ practice; use Messer's exams and Crucial Exams.

CompTIA's own timed and untimed practice tests, objective quizzes and PBQs, with a mastery score for each exam objective. Candidates find it harder and more confusingly worded than the real exam.

Great fit if your school or employer provides it, or you buy CompTIA's Practice and Exam Bundle, where it adds $30 to two vouchers with retakes.

Poor fit if you would pay $279 on its own; Messer, Dion and Crucial Exams cost far less.
