Hi artshep,
I’m glad you reached out, and I’m happy to help. First off, I recommend that you take only one more practice test at most before your GMAT and that you take the practice test in the next two days. Remember, taking a practice test requires a lot of energy and focus, and since you need to be fresh for test day, taking too many practice tests could have a negative effect on your test-day performance.
Aside from taking one last practice exam, do some light studying, such as doing focused practice and reviewing flash cards/notes from past topics to ensure that knowledge has not slipped through the cracks.
Beyond that, try to keep busy with activities other than GMAT prep: go out to dinner, go to the movies, binge-watch Netflix, go for a run … Do whatever you have to so you don’t spend the days leading up to your exam worrying about how things will go.
Regarding food, before the exam, you want to fill up on healthy, energy-rich foods. Some options are steel-cut oatmeal, bananas, peanut butter, or blueberries. In fact, you may as well start eating those foods now! One other piece of advice: Although you want to be hydrated, don’t drink so much liquid that you may find yourself needing to go to the bathroom in the middle of one of the sections. As you know, the clock doesn’t stop for bathroom breaks.
