ASVAB – General Science (GS) Test

The General Science section of the ASVAB measures your understanding of various sciences, including health, biology, Earth science, chemistry and more.

Among the questions you may find in this section are:

  • The chemical process in which electrons are removed from a molecule is called what?
  • What is the most abundant element, by mass, in the Earth’s crust?
  • Which planet is the brightest object in the sky aside from the sun and the moon?

When you sit for the real General Science subtest of the ASVAB, you will have 11 minutes to answer 25 questions on the paper version and you will have 8 minutes to answer 16 questions on the CAT-ASVAB.

A good way to prepare for the real test is to take our practice test, in which experts have written a series of questions that are representative of the content of the real exam.

Once you complete the test, review your results, being sure that you understand the right answer to each question. To improve your score even more, you may want to consult our study guide for additional tips and information.

You can then retake our practice test to ensure you understand the material. As an added bonus, the test questions will be reordered when you retake the exam, creating a new study experience for you.

Regarding the General Science subtest, your score on this part of the ASVAB will not affect your Armed Forces Qualification Test (AFQT) score. However, your score will be used to calculate some of the military composite scores that are used to determine what job you are qualified to hold.

For that reason, it is important that you take this section seriously and use our practice test and study materials to optimize your performance.

Remember, you can take this free practice test as many times as you like. Also, keep in mind that taking our practice test will also better prepare you for the experience of sitting for the real CAT-ASVAB exam – helping you to be calm and confident instead of stressed and worried on test day.
