It is also important not to get too worked up about questions that appear on your Maths mock paper, as these questions have been set by a company independent to the State Exams Commission (SEC). Your exam paper focus should always be on practising previous official state exam questions under time pressure. Replicating exam hall pressure is a brilliant way to hone your skills and really check if you can complete the question asked under the time limit allocated. I would start by taking on a short question or two against the clock, and then try a long question, until eventually you feel confident enough to take on a full paper. Constantly doing questions out from your textbook will never fully prepare you for a sit down full test paper in Maths.
