If you want to enlist in the military, or if you’re taking a vocational test at your school, you’ll need to know which are your best skills, and the ASVAB General Science Test is designed to discover your science-related skills, in areas like problem-solving, strategical thinking, and abstraction. The General Science section covers a lot of different content at a very basic level, and we have designed a formula sheet for you with the most basic formulas you’ll need to solve problems while taking this test.

Although you won’t be able to use this sheet during the actual test, you can use it to prepare, and practice by working on the practice questions for the ASVAB General Science Test at Union Test Prep, or dig deeper by consulting our Study Guide for the ASVAB General Science Test!
