If its a group presentation, make your part of the presentation yourself.
Familiarize yourself with the Slides, watch it like a 100 times so that it gets burned into your brain. The next slide should be in your memory even before it appears on the screen.
I never took any reading cards/material with me whenever I had to deliver a presentation, I left my cues in the slides I made. Be it a small clip art or a bullet heading. It diverts the attention of the audience, if you are constantly looking at your cards/reading material.
If its your first time, its gonna be hard to focus your attention towards the presentation and if you are feeling nervous about it I would say that you prepare some sort of reading material from where you could take your cues to explain the topic at hand, be warned that once you lose your track your mind will get blank and you'll be like stuttering, repeating your lines again and again and other crazy stuff like that will happen which your friends will tell you after you are done with the nightmare.
For the slides, keep them clean with minimum text and a few clip arts (icon-archive.com is a good place to get some art for your slides). If you put too much text in the slides you'd be unconsciously turning your head to read the slide which will complicate things, also it puts the attention of the audience and the professor towards the slides rather then the presentor himself. So keep the text in slides minimum.
And keep your USB clean of any unwanted pics and video clips, you don't know when your usb goes haywire and pop them up automatically in front of the whole audience. I have seen this happen to a lot of people, its one of the most embarrassing situations.
