Hi Young_Dumb
I had the same frustrations during my Mod 1. In short the exams are not perfect, the only trick apart from trying to understand what you can in the short space of time that you have to study each subject is to do practice questions over and over....then do some more. It will never be prefect, but you will get more or less comfortable with it and this will give you the opportunity to answer a good cross section of the papers. It's not a good system, I would have preffered to really know everything I was learning, but the time factor gets you in the end and it becomes about passing the damn things, so the trick is to keep at those questions....
Best of luck
... YOU WILL GET THEM....I did and I felt like the biggest simpleton the whole way through...still do!!!
