[quote=WIPilot;398779]as if there are official stamped ways that one must prepare?[/quote

The FAA made it a way we could prepare by giving us that manual. The test is made for us to take, not to study. You don't have to memorize every bit of info in a aircraft manual to pass the test. Some companies even make their tests open book. The written is usually easier than the actual oral, atleast on the Saab where I flew that was the case! SO you take the easy way out for the written, what are you going to do when the oral comes around next, study?
