I think one of the best ways to prepare for the exam is to do as many practice responses as possible, with different questions. You’ll then develop the ability to make sound arguments and really establish the response. The same goes for the Unfamiliar - you need to be able to figure out what the text is all about and how it relates to the question, so the more you try and answer the better you will get.
Hope that helps.
Cheers
