Presentations are generally pretty easy. Nowadays everyone uses PowerPoint and as long as you know how to design a single PowerPoint, you pretty much know how to design the rest. There are definitely many ways out there to improve a PowerPoint even further, but in my experience, it's never worth the effort. You should rather focus on how you'll be presenting, since that's what you'll mainly be graded on. Never insert a huge amount of text and there are certain colors you want to avoid, however, you need to make sure that your text is eligible.

As a child, the complexer a PowerPoint is, the better it is. You'll start adding crazy transitions and make text fly in.

Once you grow older, you start to realize that sometimes it's better to take a simple approach. On the other hand, you might also want to try a more professional approach. But a professional PowerPoint takes way longer to create.

In case you don't finish your presentation on time, there are a few one time methods that will certainly work.

One time I messed with a PowerPoint document so much, that it gave an error that stated that the school computer's hard drive was defect. I don't exactly understand why it happened, but that's the best excuse you'll ever get. And all you need to do is to edit a PowerPoint file with notepad and then start copying and pasting random parts. And for the heck of it, also delete a few random sections.

Just don't forget to make a backup and test if the file is properly broken.

You could also mess just with the USB or bring a defect one.
