In my Arco book math and verbal are two very distinct sections. In fact there are 2 separate math sections , and 3 separate verbal sections.
This may clear up your discrepancies between your Arco book and the actual test, and may answer some of your other questions. A new edition of Arco may have come out because the different sections in my Arco weren't separated that way. In mine, only the Air Force test is separated like that.
