TTN, around that time I realised that papers were recycled. Some questions every 2, 3 or 4 years. Flt Safety questions, my weak link, only one or other paper. Year I passed mine we had an FS question in part 1. The following day there was another; it was from their same chapter in the AP. One lucky chap had looked up the Part 1 question that night, read to the end of the chapter and breezed Part 2. The following year I told the candidates the probable questions and ones that would not occur. I was spot on.
