Perfect Your Presentation by Kidnapping Random Slides
It's one thing to follow something already on a PowerPoint slide. It's another to recall it completely from memory under pressure and technical malfunction.
This got me thinking. A spectacular way to practice a PowerPoint presentation would be to have someone eliminate one of your slides, or a section of a slide. Then, run through that altered presentation and see if you can compensate for the missing material. This will make you feel more confident about your presentation, and help you avoid being flustered if everything doesn't run smoothly. You know you can never trust a PowerPoint.
