How is the presentation being graded? Are your classmates being given survey forms to fill out rating your presentation? I personally found presentations to be very easy, much to my great surprise. What worked best for me was to create a very basic outline of what I planned to present (not what I planned to say!) and the order in which I would present it. Basically, I would never know exactly what I would say or how I would say it in advance. This practice eliminates the need to make and follow a script. Scripts can backfire if you are not careful as you may be trying to visualize the script in your mind as you speak and if you forget a part it might trip you up in your presentation. KNOW your subject matter, that is the key thing. Making eye contact is preferred, but if that is a problem try periodically 'skimming' the room looking at the hair on people's heads. Go in sync with your media aids (Power Point, etc) which should for the most part consist of 'bullets', which will help you to move along smoothly. Ten minutes is not a long presentation. Trust me, it will go fast, especially if you are 'into it', treat your subject like your special interest. You will do fine.
