Most standardized exams start at 9:00 am. You need to get to the exam by 8:00 am. Unless you live near the testing sites you will need to eat by 7:00 on the day of the exam. The human body cannot react quickly to diet changes, so you will need to trick your body into eating earlier. This way, your child’s body can digest proteins as she is sitting in the exam room.
Please realize that your child’s energy levels will deplete quickly. Your child is a teenager. Her glycogen and energy stores from the previous day will metabolize quickly due to the extreme stress she is under. The only way she will have more energy is to make sure food is being transported from her stomach to the small intestine by 10:00. Children can easily eat at 7:00. However, they can only eat at this time if they have a regular level of sleep.
