Have to say I am undecided about the rumoured release of the JAR question bank. From a professional point of view I cannot see that it will improve the quality of pilots getting through that's for sure but on the other hand at least groundschool instructors can weed out the many "dodgy" questions that currently exist.
From a personal point of view it would be nice to get a peek at the questions obviously, but to think that one could learn them all and pass? Hmmm, pushing it me thinks!
If I was forced into a corner I would say that it is not a good idea but then why do we bother with feedback from previous students?

Be honest!
