Learn more about what subjects gets tested, ASVAB general science practice questions, and what you need to do to pass.
Candidates are expected to have a broad and comprehensive understanding of a wide range of science subjects.
Questions on the human body always get asked. Candidates are expected to have a thorough knowledge of how the body is structured and how specific organs work. Candidates should also know about blood cells, such as red and white blood cells, and the functions of each major cell type.
There are three common kinds of astronomy question on the ASVAB general science test: first, knowledge of the planets and their classification; second, the movement of the moon in relation to the Earth and Sun; and third, knowledge of other celestial objects within the solar system and wider universe.
Candidates are expected to know the fundamentals of chemistry such as the atomic structure and how compounds form. You may also be asked questions about common kinds of chemical reaction and states of matter and how one interacts with another in relation to the application of pressure and heat, for example.
The ASVAB exam asks questions relating to the Earth’s structure – both underground and in terms of the layers of the atmosphere. You are also expected to know the differences (and examples) of igneous, sedimentary, and metamorphic rock; as well as structures such as fault lines in the Earth’s crust.
Expect to be asked questions about the biological classification of organisms – such as kingdoms, phylum, and orders – and to be able to identify what organisms belong to each category. ASVAB test questions also include genetics, botany, weather patterns, and the wider environment and habitats.
ASVAB general science questions also ask about physical processes and the laws that impact these processes. Expect to be asked about acceleration, force, physical laws, pressure, and how these processes interact in the physical world. Detailed knowledge of equations is, however, not expected.
