When you are studying for a test in one of your classes, make sure that you break up the studying up a little bit! If you know of your quiz a week in advance, make sure that you study a little bit of the material each day. For example, if you are taking a quiz over three chapters, make sure to review each chapter individually before the test. Then, do a quick review over all three chapters the day before the quiz. That way, you get the best results and will get a 100 on that quiz!
