A week before the test day, you’ll need to increase the amount of time you spend studying. Use this time to review challenging questions and go over answer explanations. Think through all of the logistics to ensure you understand the reasoning for the answers and avoid repeating the same mistakes on the real test.
It’s also important to take time to rest and clear your mind in the days leading up to the GMAT. It can be easy to suffer from burnout as you buckle down due to nerves and stress. Allow yourself to get enough sleep each night, exercise to increase your energy levels, and avoid thinking too much about the test to ensure you can have a clear mind and feel refreshed at the testing center.
