take more time than doing the problems carefully in the first place.
after taking the test, check your answers. go back and study anything that you feel you do not understand. you should now know if you are ready for the test. if you have been studying effectively and did well on the practice test, you should be ready for the real test. you are prepared!
if you are anxious before an exam, find a place on campus where you can both physically and mentally relax. arrive in time to arrange all of the things you will need for the test; sharpened pencils, eraser, plenty of scratch paper and a water bottle.
