Congratulations, you are ready to give this group presentation, it's going to be a great presentation. You don't have to take my word for it, you now have proof you have evidence, you've watched the video of yourself, you've done the exercises, you're not going to make the mistakes most people make, you're not going to do a boring data up. You're not going to have an awful PowerPoint with lots and lots of texts that people read. Each one of your presenters is going to be interesting, compelling, have examples, case studies, stories. The visuals, if you're using slides will actually be visual with pictures, images, things that people can see that our abstractions and little letters, and it's all going to flow nicely. You're going to be comfortable with each other because you've practiced, you know exactly how you sound.
The substance will be there, the style will be there. You put it together and it's going to be a great winning team presentation. Good luck.
