The Armed Services Vocational Aptitude Battery (ASVAB) is made up of 10 tests, including 225 questions, but only four of the tests are used to see if you qualify to join the US military. Each branch – the Marines, Navy, Air Force, etc – has a different qualifying score. The other tests – including science, electronics, mechanical knowledge – help the military determine what jobs you may be qualified to do.

Since only four areas -– Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), and Math Knowledge (MK) – are used to compute your Armed Forces Qualification Test (AFQT) score, our 24 sample questions cover just those areas. The actual military recruitment test has 105 questions in these four subjects.
