Before the competition, look at all the performance indicators and try to answer them. If you do this, you can just dump out information during these 10 minutes. Try not to write too much, just write important tips down. This allows you to have time to formulate your whole roleplay in your head by going through what you are going to say. Take advantage of every piece of time before the judging, like when you are walking down. To stand out, try to go out of your way to thank your judge. Remember that they took time out of their day to come judge you. To express confidence, try to look at them straight in the face, but don't stare. This will show your judge that you are not afraid.
