Hi there Bandit
Not to worry it's not a silly question, i also haven't studied at BGS. I have heard they offer a superb high calibre training as do Oxford, whom i study with.
When i say the Bristol feedback i mean the online database. It costs £50 for 3 months access. As has been said in earlier replies use the feedback to highlight and brush up on your weaker areas. Learn it at your peril!! I cannot emphasise how important it is to understand the method and how to work out the correct answer, of course it's nice to go into the exam and be presented with questions you've seen previously. Conversley this happened to me in my gen nav exam, virtually all the questions were word for word from the Bristol, but it really isn't worth taking the risk expecting the exam to be so!! Know your stuff and using the on line database will give you an idea of the areas the JAA tend to focus their questions.
In an earlier post you mentioned you purchased feedback from e-bay, i strongly suspect this is the Volare feedback!! I would advise you to use it very carefully as there are quite a few errors in their quoted answers!!!
My advice is stay safe and use Bristol's online database!!
Hope this helps and the very best with your training
