On the CAT-ASVAB, General Science has 15 scored questions with a 20-minute time limit. The paper-and-pencil version has 25 questions in 11 minutes. GS covers biology, chemistry, physics, earth science, and space science at a high school level.
General Science covers: biology (human body systems, cells, genetics, ecology), chemistry (atoms, molecules, chemical reactions, periodic table), physics (motion, forces, energy, waves), earth science (geology, weather, climate, rocks), and space science (solar system, stars, planets). Questions are at a high school level.
No. General Science tests basic high school-level science knowledge. You don't need college-level chemistry or physics. Focus on understanding fundamental concepts like how the human body works, basic chemical reactions, simple physics principles, and earth science basics.
GS is scored as a raw score (number correct) converted to a standard score. While GS is not part of the AFQT score, it contributes to several line scores that determine job qualifications, including General Technical (GT), Electronics (EL), and Mechanical Maintenance (MM) scores.
