The Mathematics Knowledge subtest is designed to determine your abilities in high school-level math, and it makes up a large part of your AFQT score. Remember:
  • Use the acronym PEMDAS to remember the order of operations (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
  • Double-check each step of your work to make sure a small error isn't costing you the correct answer.
  • Don't be afraid to scribble out your work and start over if you become confused. You have access to unlimited scratch paper and pencils, whether you're at a MEPS or a MET site.
