The ASVAB (Armed Services Vocational Aptitude Battery) is the gateway exam for enlistment in every branch of the U.S. military. Your AFQT percentile and line scores determine which branches you qualify for and which jobs you can train for. AcePrep is built for one outcome: hit the AFQT score you need on test day. This is not a quiz bank. AcePrep is a complete exam prep platform built on cognitive science - confidence calibration, spaced repetition, stress inoculation, and progressive difficulty that adapts as you learn. Know exactly when you are ready for test day. PASS GUARANTEE ON EVERY PRO PLAN Earn your Exam Ready Certificate, take the ASVAB within 14 days, and if you score below AFQT 50, we refund your last subscription payment. Full details in our Terms of Use. HOW IT WORKS AcePrep measures what you actually know - not just what you can guess. Our confidence calibration system tracks four dimensions of mastery: what you know and know well, what you know but doubt, what you get wrong but thought you knew, and what you are still learning. This precision targeting means you study what matters most. Progressive difficulty takes you through four exam simulation levels - Foundation, Intermediate, Advanced, and CAT-ASVAB Simulation - so you build real competence before test day. 4,000+ QUESTIONS + 290 STUDY MATERIALS - 2,500 multiple-choice practice questions across 23 categories - 1,500 rapid-fire true/false recall questions - 290 study materials (guides, tables, formulas, mnemonics, glossary, quick facts, exam tips, visual references, exam prep) - All 9 ASVAB subtests: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics, Auto & Shop, Mechanical Comprehension, Assembling Objects - AFQT formula: 2(WK+PC) + AR + MK - AFQT-heavy weighting in Practice Tests 8 STUDY MODES - Daily Drill - 50 timed questions to build your daily streak and identify weak spots - Practice Quiz - customizable quizzes by subtest or category - ASVAB Practice Tests - 90 questions, 100-120 minutes, 4 progressive levels - AFQT Focus - 40-question session targeting the four AFQT subtests - Smart Review - spaced repetition targeting your weakest areas - Rapid Fire - true/false recall training with instant feedback - Flashcards - swipe-based review for every category - Review Mistakes - revisit and master every question you missed BRANCH QUALIFIER PREDICTION AcePrep predicts your AFQT percentile from your per-subtest accuracy and shows which branches you qualify for - Army/Navy/Air Force/Space Force 31+, Marines/Coast Guard 32+, Competitive across all branches 50+.

Most TACHS prep starts with drilling. That is the fastest way to waste the time you have, because you cannot study everything at once and you do not yet know what is weak. This app starts with a 28-question diagnostic, about half an hour. It is not a score. It tells you where to begin, and builds a study plan around your test date. BUILT FOR THE TEST AS IT IS NOW The TACHS runs on screen in six timed subtests, one after another: Reading, Written Expression, Mathematics, and three short Ability subtests of figure puzzles. About 2 hours 10 minutes of testing, with a short break between subtests. Inside a subtest you can skip, mark and come back; once you submit a subtest you cannot return to it. There is no penalty for a wrong answer. Practice here runs by those same rules: six subtests, each on its own clock, answer choices lettered the way the test letters them, a cross-out tool for choices you have ruled out, a highlighter on the reading passages, and a basic calculator in the math subtest, the way the test platform now provides one. The format itself is a lesson, so the shape of the day is already familiar. THE ABILITY SECTION, DRAWN Figure matrices, paper folding, figure classification: puzzles most students have never seen before test day. Here they are drawn on screen, hundreds of them, with a worked explanation of the rule behind each one and short lessons on how to read them. WORKED ANSWERS, NOT ANSWER KEYS Every question shows the method, step by step, and then checks the answer against it. Get one wrong and you find out why, not just which letter you missed. MADE FOR iPad, INCLUDING APPLE PENCIL On iPad the question sits beside a scratch pad you can write on with Apple Pencil or a finger, and your working stays next to the worked explanation afterwards so you can compare them line by line. Reading passages open side by side with their questions. WHAT IS INSIDE - 1,940 practice questions across the four sections - 93 lessons, each with worked examples - 89 reading and Written Expression passage sets - Full practice tests in the six-subtest format, about 176 questions each, drawn fresh to the same blueprint every time so a test is worth sitting more than once - Adaptive Practice, a shorter mode that picks what to ask next from how you are doing and tells you the difficulty level you were working at in each section - A one-page report your child can send you when they want to show how it is going The pass unlocks all of it. What stays free is next. FREE, PERMANENTLY - The 28-question diagnostic and the study plan it builds - Your error journal and your progress, always - 10 new questions a day, up to 150 in total - Unlimited redo of anything you have already answered Your progress stays on this device and in your own iCloud, and is never locked: with or without the pass, and after it expires. THE PASS: ONE PAYMENT, NO AUTO-RENEWAL It lasts 365 days from the day you buy it, it does not renew itself, and you will not be charged again. No subscription to remember to cancel. It unlocks every full practice test, the whole lesson library, and the whole question bank with no daily limit. NO DATA COLLECTED No account. No sign-up. No analytics, no advertising, no tracking, and nothing sold to anyone. Your work syncs privately between your own devices through your iCloud account and goes nowhere else. The App Privacy section on this page says "Data Not Collected" because that is literally true. Written for eighth graders sitting the TACHS for the Archdiocese of New York, the Diocese of Brooklyn and Queens, and the Diocese of Rockville Centre.
