About the General Science Section
The General Science (GS) section is one of the 9 subtests on the ASVAB (Armed Services Vocational Aptitude Battery). It covers biology, chemistry, physics, and earth science.
Your GS score contributes to composite line scores used by military branches to determine which jobs you qualify for. A higher GS score opens up more career options across the Army, Navy, Marines, Air Force, Coast Guard, and Space Force.
Our 4 interactive lessons take you from fundamentals to test-ready mastery. Each lesson includes concept explanations, worked examples, and practice questions with instant feedback.
