How do I choose a question in the exam?

First of all you need to break down the wording of each question and find key words (e.g. in a question asking to discuss the 'unsayable' this is the key word that needs to be addressed) and pick out the ones with the most relevance to what you've focused on in your revision. Don't be overwhelmed by the number of questions, just relax and take your time to read them all properly.
