Armed Services Vocational Aptitude Battery
The Armed Services Vocational Aptitude Battery determines which military occupational specialties you qualify for and whether you meet minimum enlistment standards. Your AFQT (Armed Forces Qualification Test) score, a percentile ranking derived from four of the nine subtests, is the single most important number in your military career decision.
The CAT-ASVAB (Computer Adaptive Test) presents approximately 126 questions that adjust in difficulty based on your performance. Each subtest is timed separately, and the adaptive format means getting questions right early produces harder follow-ups worth more toward your final score.
The AFQT score is a percentile ranking calculated from Arithmetic Reasoning, Mathematics Knowledge, and a Verbal Composite (Word Knowledge + Paragraph Comprehension). A score of 50 means you performed better than 50% of the reference population. Minimum qualifying scores vary by branch: Army 31, Navy 31, Air Force 36, Marines 32, Coast Guard 36, Space Force 36. Higher scores unlock more MOS/rating options.
The app covers all nine subtests with questions structured to match the difficulty progression of the CAT-ASVAB. Confidence calibration catches the subtests where you think you're solid but aren't. Spaced repetition keeps formulas and vocabulary locked in. The exam readiness algorithm tracks your AFQT components separately from technical subtests so you know exactly where to focus.
