When other people are doing their presentation you will notice that you probably aren't listening. People will look in your direction but not be judging you or anything (they probably won't even be listening) so don't get nervous about people thinking you aren't doing well or something. Just try to talk slow and calmly and if you make a mistake laugh it off.
