I am not going to comment on the cheating thing but, I just want to illustrate the different ways to study for an FFA written. Way back when I took my flight engineer written (yup, airlines used to require that) I went to ATP to take it. Along with myself there were two USAF KC-135 guys and one other civilian that flew Chieftains. I was just a lowly CFI at the time.
The way ATP prepares you for the test is that you take practice tests and study for the first half of the day. Later, you take the test. So, I spent all of my study time memorizing all of the answers and coming up with various mnemonic devices. Things like, "all questions about W&B are C".
When it came time for the test I breezed through in fifteen minutes and got a 98. I decided to hang around the school and chat with the instructors there who were friends of mine while I waited for the other guys to finish.
The Chieftain guy was out in another fifteen minutes, did basically the same thing as me and scored in the high 90's as well. TWO HOURS later the USAF guys came out. Instead of just memorizing answers they actually tried to learn the stuff (which was pretty archaic even then). They both scored in the low 90's.
Who took the test correctly?
