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.You can relax this time around … well, just a little. The General Science subtest has no bearing on your Armed Forces Qualification Test (AFQT) score. On the other hand, your score on this subtest is used to calculate some of the military composite scores that are used for job qualification purposes.
