just completed all the ATPL exam which i did through bristol. not as much about the question bank anymore and most questions have been changed for the fact of learning the theory and the not the answers. as the subject AG had questions which referred to 2 quotes about the operations and you had to choose the answer which stated if both was correct, neither was correct blah blah blah
A few cadets from oxford which i spoke to at shuttleworth said they bought the bristol question bank (which you can do online now) and they used it and said it was better than oxford.
different subjects require different ways of passing them theory and question bank.
