text: Prepare adequately (study) for at least a week or more and don't stay up late each nite. Get plenty of rest on the day of the exam. Then on exam day, DO NOT EAT anything 1 hour before the exam. Eat something (high protein and non-greasy food only) 2 to 3 hours before the exam. Then right before the exam, drink soda pop (Mountain Dew or JOLT is preferred). This last advise is crucial. If you can't find any colas like Coke or Pepsi, drink honey mixed in water. You need the sugar, bottom line, specifically your brain. If you eat before the exam, your brain would be too busy to help you concentrate so eating before the exam is a no-no.
