Emphasize & accentuate the narrative
2-3 minutes per slide
Its easy to write slides that are walls of text. But remember that as soon as you put something in front of your audience they'll start reading it. And in general, people are very bad at focusing on two things at once. So guess what, you just lost your audience and now need to pull them back into your talk.
So remember, this is an example of a poorly constructed slide.
With text, less is more
Be careful with visuals
Stick to your narrative
Make sure you've timed yourself
Know your transitions
Know your material
