What the Course Entails and Exam Details

The General Science subtest covers a broad domain of foundational scientific knowledge. While there is no specific "course," candidates must demonstrate proficiency in four key areas:

Life Science (Biology): Topics include cell structure and function, human anatomy and physiology, genetics, evolution, and ecology.

Earth and Space Science: Candidates will be tested on geology, meteorology, astronomy, and oceanography.

Physical Science: This area covers fundamental concepts of chemistry and physics, including atomic structure, chemical reactions, forces, motion, and energy.

Scientific Method: A general understanding of how scientific inquiries are designed and conducted.

What to Expect in the Final Exam

The ASVAB is now primarily administered as a computer-adaptive test (CAT-ASVAB). This means the difficulty of the questions adjusts based on your answers.

Format: The exam consists entirely of multiple-choice questions.

Timing: In the CAT-ASVAB, you will have 8 minutes to answer 15 questions. If you take the paper-and-pencil version, you will have 11 minutes to answer 25 questions.

Scoring: Your score is combined with other subtests to determine your overall Armed Forces Qualification Test (AFQT) score, which dictates enlistment eligibility. The specific GS score influences which military occupational specialties (MOS) you qualify for.

Calculators: Calculators are not permitted during the General Science subtest.

How to Study and Exam Centers

Preparation for the ASVAB General Science subtest should focus on reviewing fundamental high school science concepts and building testing endurance.

Study Strategies: Start by taking a baseline ASVAB General Science practice test to identify weak areas. Then, utilize study guides that focus specifically on the high-yield topics within biology, chemistry, physics, and earth science. Practice with timed quizzes to get accustomed to the fast-paced nature of the computerized exam.

Exam Centers: You cannot register for the ASVAB independently. The registration process is initiated through a military recruiter. Once scheduled, you will take the official exam at a Military Entrance Processing Station (MEPS) or a dynamic Mobile Examination Test (MET) site.
