Ironically, later as a corpsman I had to administer the test, and had it memorized. If I could have memorized the book before I took the test I would have been fine.
This reminds me of a story from an older friend...
He was born in East Germany, eventually escaped, and came to the U.S. during the Vietnam War. Rather be drafted, he enlisted in the Army.
During boot camp, they asked if people were interested in Special Forces. He wasnt sure what that was but "raised his hand" anyway - probably because it got him a little extra pay. During the process, they asked if he knew a foreign language, which of course he did.
He was given the test for German. No problem.
Growing up in East Germany, he obviously knew Russian as well. So, he took that test.
He also knew some French. So, what the hell, he said give me that one too.
Part way through the French test, he realized all the questions were identical to and in the same order as the German and Russian tests.
So, after he aced French, he just kept going knowing the order of the questions and the answers.... Cantonese, Spanish, Italian, and Arabic...even though he didn't know a lick of any of them. Passed them all.
Fast forward through his SF career to 9/11. He's in IRR or something and gets a "call". "Col, we're in need and our records indicate you're fluent in Arabic?"
He's like, "Yeah, funny story..."
