Question banks will be your best friend sir
Use them, use them, use them .... and then use them some more.
Now I'm not advocating blind memorisation of answers (although that will be the case for a couple of questions which make no sense to anyone other than the infamous 'examiner') ... what you need to do is use the question banks as your guide for the learning, they'll guide you as to what you really need to know, studying hundreds of pages of books and writing out notes on something which is never gonna be examined is a sure way to add stress and not get the desired results.
