Dress nicely, no wrinkles in clothes. Appearance is important. Have your materials ready, make sure any charts, graphs, etc. are clear and concise. Speak clearly and loudly, make eye contact with your audience.
Try to not be nervous as the audience will pick this up. Be prepared and do not attempt to memorize what you are going to say. If you memorize, a slight interruption or stumble will put you in a panic mode and then the entire presentation is lost. Look over everyones head, they will think you are looking at them.
