About the ASVAB diagnostic
Prepare for the Armed Services Vocational Aptitude Battery: all ten CAT-ASVAB subtests, with the most depth on the four AFQT subtests (Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, Mathematics Knowledge), plus AFQT scores, line scores and test-day strategy.
This diagnostic is a starting point rather than a practice exam: it samples the whole syllabus so you can see which units you already know and which ones need the work, before you spend study time guessing.
