Well I am also doing the exam and I am doing a lot of pass papers and reading a lot of articles and trying to identify the purpose of the text ect. I do 1 pass paper a day and I will ask my teacher to mark it and tell me how I can improve. Also time your self for each question that way you can get use to the pressure. In addition, try and read a books to help improve your vocabulary. I don't have much more to say because I am in the same situation as yourself so GOOD LUCK.
