The book contains a diagnostic test, plus three full-length practice tests that replicate the actual format and timing of the ASVAB, so you can “practice for real” before test day. Two of the book’s practice tests are included on our TestWare® CD with automatic, instant scoring analysis and powerful diagnostic feedback. On-screen detailed explanations of answers help you pinpoint your strengths and weaknesses, allowing you to focus on areas in need of further study. Our complete ASVAB test prep package also includes an 8-week study schedule and test-taking strategies for succeeding on the exam. 
The content of the test has been clearly laid out, but there is still a ton of information concerning the actual place where the test is administered and the time that is allocated for each section. The computerized test is administered in a “military entrance processing station” (MEP) or a satellite region that is identified as a “military entrance tests site” (MET). The difference in the two locations is that the METs are the places that are responsible for administering the written test, while MEPs are the places that administer the computerized tests.
The various armed forces adopted all of those aspects in 1976. At that point in time, the test was in its written form rather than today’s more common form (computerized test format). The written form covers all of the previously mentioned areas as well, which is why both forms are still available. All-in-all that answers the question concerning the intention of the test.
