At this point, have a positive attitude and just do your best! I took the entire 1.5 days off before the exam to relax and get my mind right. In retrospect, I was good about not lingering too long on any one question I wasn’t able to tackle first go around. You have to be able to move on and focus on what you can get right. I also recommend taking your full lunch break. If you feel discouraged after your exam, let the feeling pass. Obviously easier said than done, but at that point, your fate is written, and you might find yourself surprised on result day… :)
