So, my usual method is to rush and finish the test as fast as I can so that I have more than half the time to check, however even with all this checking time I continue to make mistakes because I just find it hard to pick out errors and I don't really reread the question as well as I would the first time. So my question is should I take it at a slower pace (about 2-2.5 hours) and leave less time for checking and and try to get it right the first time. And I seem to be making most my mistakes mid way through the exam (questions 13-15).
