Take your time to analyze each. And above all - leave your phone in your car when you take the exam. I just read a pretty severe fine for using the phone in the testing area.
I would read them over and over again, on the toilet, killing time waiting on appointments; I'd keep them with me and fill time while reviewing them.
I would also create flashcards out of the multiple choice questions, putting key terms on one side and turning them into 'fill in the blank' answers.
I did what Broker Martin said as well, and it became more convenient and more interactive with the flashcards. Everyone has their own learning style. Good luck.
