Presentation time!

• Remember that you have 3 minutes. That's 3 minutes exactly. Not "around 3 minutes" or "3 minutes more or less" or "It felt like 3 minutes to me," but exactly 180 seconds.

• Typed up, a 3-minute presentation equals about a page and a half of text, double-spaced, Times New Roman 12. That's 375 words.

• Speak more slowly than you in everyday conversation, so that your audience can absorb what you're saying. As a rule of thumb, it should feel like you're talking a bit too slow.

• Rehearse! Rehearse! Rehearse!
