How each lesson works

Every lesson follows the same seven steps, so you always know where you are.

The steps of a lesson

Step	What you do
Brief	What the lesson teaches and what you will be able to do by the end.
Probe	A few questions before any teaching, to find where to focus.
Teaching cycles	Short pages with worked examples, each followed by drills with coach notes.
Walk-through	A real-format question solved step by step, with the coach panel open.
Guided practice	Real-format questions with hints you can open when you need them.
Check	New questions under test conditions in the CAT frame.
Debrief	Your check score, every mistake linked to the page that teaches it, and one takeaway for your notebook.

Frequently Asked Questions

All ten CAT-ASVAB subtests: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Auto Information, Shop Information, Mechanical Comprehension and Assembling Objects. Two orientation lessons open the course: how the ASVAB works and what your scores mean, and strategy for an adaptive test.

Each lesson takes about 25 to 60 minutes. The 45 lessons add up to roughly 33 hours. You can take them in order or go straight to a subtest.

A short brief, a quick probe to find where to focus, teaching pages with drills, a walk-through with coach notes, guided practice with hints, a check under test conditions and a debrief with one takeaway for your notebook.

Yes. ASVAB Prep includes five fixed practice-test forms and a random mix, delivered the CAT-ASVAB way: ten separately timed subtests, one question at a time, the next question chosen from your last answer, with tryout questions, directions and a practice item before each subtest.

Yes. Lessons, practice sets and practice tests save to your account, so you can leave and resume on any device. The free daily questions and the free fixed-form tests on this site save to your browser only.

The ASVAB plan is $39 a month, or $29 a month billed every three months. The course, practice by subtest, the adaptive practice tests and the question bank are all included.
