maxwell4065 implies ......
....hhhmmm, I think you've inferred. I am inferring from Maxwell's question ( and only he can confirm his implication) that, as he wants to do well, he wants to know HOW closely matched the BGS question bank is matched to the CAA's in terms of standard of style.
As a shot in the dark (and I have never had an aviation job interview) but might not one be asked technical questions? And these would ne be multi-guess so an understanding would be required in this situation.
