Practice it. Practice it over and over again. When it comes time to do the presentation, have a brief outline that you can reference. But don't try to read a word for word presentation. When you make a mistake move forward. If you skip a sentence or a paragraph, so be it. For everyone else this is about the presentation. For you it's about having a positive experience standing in front of your peers. Do your best and know that the moment you stand up there and utter your first syllable, you've achieved victory. Any positives from that point forward are just gravy.
