Planning for the actual day of the exam is very important for you and can ensure the best chance of performing well. Have a solid breakfast, and make sure to bring healthy and nutritious food. Give yourself plenty of time to arrive at the location of the exam without being in a hurry – especially if your exam is located where you have not been before.
Be sure to know what exam aids and other equipment is allowed and necessary for the exam. Pack the day before. You can also make an appointment with a friend to call you on the morning of your exam, to check on whether you are on your feet and ready. Thus, you don’t have to worry about oversleeping.
When you don’t have to worry about practical things or anything else, you can spend your energy focusing on your actual exam.
