General Science for the ASVAB
Broad science review for life science, earth science, and physical science fundamentals
Technical and Line-Score Subtest
Biology, earth science, and everyday physical science concepts
General Science feels much more manageable when the focus stays broad, practical, and repeatable. MeritMarch helps you review the science ideas most likely to show up without getting lost in textbook-level detail.

🧪What General Science covers on the ASVAB
General Science is a broad survey subtest. Instead of going deep into one discipline, it checks whether you recognize common ideas from life science, earth and space science, and basic physical science.
That makes this section more about clear fundamentals than advanced detail. If you can sort through diagrams, vocabulary, and everyday science concepts with confidence, you give yourself a better base for science-related line scores and a cleaner overall prep plan.
📘Core topics to review for General Science
Strong General Science prep usually means reviewing the concepts that appear again and again in school-level science rather than chasing edge-case facts.
Life science basics
- Cells, tissues, organs, and body systems
- Genetics, heredity, and basic evolution concepts
- Plants, animals, ecosystems, and food chains
- Health, nutrition, and common biology vocabulary
Earth and physical science basics
- Weather, climate, rocks, and earth processes
- Solar system basics and major space concepts
- Matter, energy, heat, force, and motion
- Simple experiments, diagrams, and science wording
Keep your ASVAB prep moving.
Use a clearer study path, repeat the right fundamentals, and get ready for test day with more confidence.
🧭How to prepare more efficiently for General Science
General Science can feel random when the review is random. The better approach is to rebuild a small set of high-frequency concepts and get used to the question language that makes simple science look harder than it is.
Common mistakes
- Trying to memorize trivia instead of understanding broad categories and relationships.
- Ignoring diagrams, labels, and process questions that reward calm reading.
- Spending too long on advanced science when the section mainly rewards fundamentals.
- Not reviewing terminology enough to recognize what the question is really asking.

🎯Who should prioritize General Science
This page matters most if science-heavy school content feels distant, if technical career paths matter to you, or if you want your broader ASVAB profile to look stronger beyond the AFQT core.
Practical study plan
- Review broad science categories first, then practice mixed questions.
- Use short, repeated study blocks instead of occasional long cram sessions.
- Keep a list of science terms and diagrams that slow you down.
- Pair this page with Math Knowledge and Arithmetic Reasoning if you need a stronger technical base.
