From experience I've found that the more someone freaks out, the more likely it is that they'll be the ones dragging the presentation down. Confidence is half the grade. The last presentation I gave was with me and two others, each 5 minutes. We made it an hour in advance. Even when I really want to make a great and long presentation, I don't start until a few days before. If you really want to nail down the structure and make it like a story, go watch this.everyone but me is freaking out.
That video was awesome, thank you! I've been watching other videos on the same channel, it reminds me so much of listening to podcasts. I've written myself a script to appease them, with full knowledge that I'll probably be rewriting the whole thing the night before the presentation. C'est la group work.
