Presentations

[Will17]

Hello!

I'm preparing some questions to (or for?) my colleagues, can you tell me if they are correct, please? :

-What was your widest audience?

-What types of visual aids do you generally use for your presentations?

-Do you wear something special for your presentations?

-How long do you generally rehearse a presentation?

-Do you have a kind of ritual before giving a presentation?

-What's the key to a good presentation?

-Is there something you never do before giving a presentation?

-How many people are usually in the audience for your presentations?

-Give a formal and informal phrase to welcome your audience

-What are you going to present us next time?

Thank you very much
Will
