I wasn't expecting the performance paper to be the same as the question banks by usually you can apply to ethos from the question bank to get the answer, some of the questions I didn't see any method to, for Istanance figuring out a airspeed such. Maximum endurance from the maximum range which was given, that may not be the actual question but it was like that for two or three of them. I did the oxford course for performance and didn't see it in there, will see the result and so it again I suppose.
As for gen nav I didn't see any major surprises in May, was pretty much typical questions you'd find in question banks, I'd say most where word for word from question bank. Unite a few calculations in ground speed and drift...at least 5 or 6 of those.
