Meteorology
I would say it is pretty good for this subject. Although they are constantly adding and removing quetions to the JAA question bank so back in August I think I had seen around 60% of "similar but not quite the same" questions.
However Bristol's feedback they dish out to students at the brush up course is far superior for Meteorology than the online question bank.
The Bristol feedback that I borrowed from a friend helped me obtain not only a pass in the exams that I took but also obtain all of my marks in the mid to high 90's.
Wish I had used Bristol for the course now... ah well in hindsight and all that!
