Get several nights of restful sleep before the test. Eat a good breakfast on the morning of the test. Have everything you need, including your calculator and directions to the testing site, laid out the night before. Leave plenty of time for travel to the testing site. Relax. High anxiety won't help you test well. Expect the unexpected. Students have been known to get physically ill at these tests. Don't let clueless proctors and cheating students distract you. Stay focused on your work.
