A good way to improve on your math tests are to study right when you learn that you are going to get the test. Let's say that today, you have just learned that in one week, you are going to have a test on Monday. Everyday until next Monday, you should study 15 or more minutes. You should also go onto Khan Academy and find the skills that you are doing the test on, and practice them on there.
