On the CAT-ASVAB, you answer one question at a time and can’t go back and change your answers once you’ve submitted them. If you answer a question correctly, you get a more difficult question, but if you are incorrect, you are given an easier question to answer. This is called “adaptive” testing. Once you finish a section you can go on to the next section at your own pace.
Paragraph Comprehension tests the ability to obtain information from written material. Students read different types of passages of varying lengths and respond to questions based on information presented in each passage. Concepts include identifying stated and reworded facts, determining a sequence of events, drawing conclusions, identifying main ideas, determining the author's purpose and tone, and identifying style and technique.
The Armed Forces Qualification Test (AFQT) derives from the more comprehensive, 10-subtest Armed Services Vocational Aptitude Battery (ASVAB). Scores on the four ASVAB math and verbal subtests are used to calculate an AFQT score, which determines whether an individual is generally qualified to enlist. Performance on all 10 ASVAB subtests, meanwhile, ascertains an enlistee's qualifications for specialized work within the military and possible incentives for enlistment.

Mathematics Knowledge tests the ability to solve problems by applying knowledge of mathematical concepts and applications. The problems focus on concepts and algorithms, and involve number theory, numeration, algebraic operations and equations, geometry, measurement and probability. Mathematics Knowledge is one factor that characterizes mathematics comprehension; it also assesses logical thinking.
