ASTB

The Aviation Selection Test Battery (ASTB) is used by the U.S. Navy, Marine Corps, and Coast Guard as one criterion used in making selection determinations for officer aviation program applicants. The ASTB is used by the Navy Personnel Command (NPC) and Commandant Marine Corps to select candidates for the Navy and Marine Corps pilot and flight officer programs.

The ASTB is a challenging test so you should study for it before you take it. If you already have some civilian flight instruction parts of this test will be easier for you.

These are books that you should buy if you plan on taking the ASTB. Only review the parts that pertain to the ASTB. The Officer Candidate Tests book is a good review for the math/verbal portion of the tests. These books can be bought at most big bookstores or at an online bookstore.
