Did you just post on the BGS Forum? I've replied there but I'll also reply here. It's not really specific to BGS so for non-BGS people the mod 2 subjects are:-
Air Law, Ops Procedures, Radio Nav, POF, Performance & AGK
I got my worse result on AGK which I feel boils down to the fact that it is such a diverse subject requiring you to learn loads. The AGK question bank is also very large meaning that the feedback may not be as good.
I found Radio Nav the easiest. Second easiest was Ops Procedures, however you have to be careful with Ops Procedures as JAA rules and ICAO rules can be different so a question that would be one answer in air law is a different answer in Ops Proc.
Hope that helps.
