Hi Captain Y,
From my own experience on Module 1 i found that the Bristol QB was in the most parts a true representation of the actual exam questions themselves so if you are getting high marks on the QB you should be ok IMO. Thats said, i thought that subjects with less' factual' answers were more hit and miss such as in Flight Planning, Nav etc, although this may because i found it more of a chore using the QB to do these subjects so probably had less experience of the banks questions......folding them charts is a drag man!!!!!!
All in all you can't go far wrong if you keep working on the QB and refer to the books if you have any weaker areas. I have M2 exams coming up in April following March brush up so am hoping nothing major has changed in the last 2 months!!!!!! We'll see!!!!!
All the best and happy studying.
