Interesting thread!
I'm just about to go on the module 1 brush-up with BGS and it feels like its taken me an age to get this far!
I have a degree in a social science and an MSc in an aviation related subject, for which I had to learn (quickly) the basics of aero engineering amongst other things.
In terms of comparing the ATPL with the MSc they are both very different challenges. During the MSc there were moments when I convinced myself I would never get my head around the problem...it was just way above my possible understanding! These thoughts have not occured during the ATPL (apart from gyroscopes maybe)! But I have found myself thinking that I will never be able to retain the sheer volume of information that is required.
I think that it was it boils down to...it's not rocket science, but there's shed loads of it!
(And is it normal to feel that you have'nt learnt anything before you go for the brush-up)???
