I was nervous. This was in front of a class of 30 students. I had 4 note cards to look at but after glancing at them once, I decided to just wing it. I realize towards the end I made a mistake about solving the yellow cross, I referred to it as a white cross. After my speech, two classmates were assigned to ask me questions. I was surprised when many people put their hands up afterwards to ask questions. Several hands went down after the first question of "What is your fastest time?" At least I know I had everyone's attention.
