Keep your schedule and eating habits the same. Do not eat a huge breakfast if that is not your normal routine, it would be horrible to lose time with a stomach ache. Go to sleep at your normal time, if you can't sleep don't worry about it, trust me adrenaline will get you through tomorrow. I guarantee you will not fall asleep during the exam. Do take a sweater in case the center is cold, you can wear a dark colored if you plan on using a sleeve to erase..I like that idea, anything to save time. Check the markers you are given and make sure they are new, don't let them give you some dried up markers, you pay enough for the exam you are entitled new ones..
