Using scientific strategies to improve your score

As you study for this subtest, you may feel overwhelmed by facts and figures. General Science requires a lot of straight-up memorization. You’re presented with questions about facts you probably learned in high school in various science classes, such as health, Earth science, biology, and chemistry. If you don’t know that Earth is the third planet from the sun, then all the other science knowledge you have won’t help you one bit when the question asks, “What is the third planet from the sun?”

tip Instead of trying to remember nine million individual facts, spend some time reviewing the general principles behind the facts. Think about how the facts relate to each other. Looking at the big picture is an effective learning technique.

You have 11 minutes to answer 25 questions on the paper version of the General Science subtest, or you have 8 minutes to answer 16 General Science questions on the CAT-ASVAB. That comes out to about 26 or 30 seconds per question, so there’s no time to dilly-dally. For the most part, you either know the answer or you don’t. If you don’t know the answer, you can always guess (check out Chapter 3 for tips on guessing on the ASVAB).

You can relax this time around … well, just a little. ...
