Being punctual on the test day is very important for any competitive test. GRE is not an exemption, because if the test takers don't reach the test center on time, they will not be allowed inside the test center and the test fee you've paid will get wasted. So, it is heavily advisable to reach the test center before 30 minutes to prepare yourself for the test.
Test takers should not take any food or beverages or drugs inside the test center.
Sometimes test takers worry when they have reached wrong test center and the test start time is nearing, this usually happens when you don't know the test center location accurately, Hence, know about your allotted test center location one day before to avoid upsets on the test day.

Do not prepare the previous day, because the preparation on the previous day might cause confusion in the whole preparation.
