Your best approach is to try/plan questions from recent exams. Don’t just read them, then turn to the answer otherwise they are wasted. When you plan/write your answer compare to the model answer and really analyse the differences to see if you have not addressed the requirements properly or not picked up and used information in the question. Obviously the model answer contains much more than you could write. Try to look for fundamental differences.
Write a few out properly, sticking to the time allowance and aiming for at least 1.25 pages /10 marks.
