Roger, you probably did very well because nobody helped you ! The "cheat" mentality in the industry is phenominal. Every one dashing around looking for answers to interviews, sim tests, renewals and psych tests. For the latter, remember, there is often no correct answer. Instead, a personality profile is built up through consistency. Flit about with answers you may "think" are correct and an inaccuarate picture will result. BE YOURSELF.
My last type conversion was with a cheater. He managed to get hold of the sim profiles handed to the instructors. He offerd them to me. I declined, rather bravely, claiming that I preferred to "know" the aircraft rather than give the impression, falsely, that I did. Of course he whizzed through everything with grade "A" 's. I needed several repeats but in exchange, got some seriously good instruction. I never felt comfortable Dead Heading behind him in J !!
