The order of drawing lots is not directly related to your score, so don't think about it just because you draw lots in front or behind. As long as you do enough preparation and study and do well in the examination room, your score will satisfy you.
Maintain positive optimism, full of confidence, full of vigor, and smile at the examiner. Don't think that the examiner is a radish cabbage, but treat the examiner as a kind elder and communicate with the examiner naturally.
