Do your presentation on "the proper techniques of giving a presentation" showing examples of how to and how not to look, stand, place your hands, use grammer, etc....that way if you screw up...noone will really know if you meant to do it or not

 

You can also do something like how the S2000 is better than some cars and I guess you can go into detail about what options you can do to the S2000 like ITB's, Turbo, and/or Supercharged. Also what the +/- 's of each choice is.

 

teach cpr and involve a hot female classmate as your test dummy...thats what i did, she was game for it, got an A

 

Confidence and sense of humor are key. Both demonstrate command. Without them, you look scared.

I suck at a lot of things, but speaking in front of a crowd has always given me a thrill. If it does not scare you, you can have an audience eating out of your hand easily.
