About the workbook

One step worth understanding.

AptiStep helps you slow down at the part of a question that does not make sense yet.

A focused starting point

This workbook covers foundations in Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension. It uses original examples and plain explanations. It is not a complete ASVAB course or an official test simulator.

What you can use today

The website includes 10 lessons, an 8-question starting-point check and a 6-question math workout. You can use them without an account. The app is free on iPhone and Android: download it from the App Store or Google Play.

Who is responsible

AptiStep is published by Certloom Learning. Questions and corrections can be sent to certloomlearning@gmail.com. We do not claim military affiliation or endorsement.

Honest limits

A short practice result cannot predict an official AFQT percentile or determine enlistment eligibility. We report your performance on our own items and help you choose a useful next lesson.
