I think many come in with their eyes closed. I know on most navy/military courses, they do a "good" review or stomp their feet or make it very obvious whats going to be on the exam. I know BAC is not like that, neither was BEW. One has to ask questions and study!! I recall, one of the classes we did with the navs. Was a review period prior to the exam. Instructor came in, asked if there was any questions, at first no one said anything, he then started to walk out of the class, lol wasn't long before we started to ask questions. I knew after I was unsucccessful on a few exams, because I wasn't studying I required a new game plan. I owe a lot to one WO on the crse!! Best of luck.
