aka DECA

For those of you who don't know about DECA, it is a business competition with 3 parts: a written, a roleplay, and a presentation of your written.

The written is a 10-page BS about a business, the roleplay is a 7-minute BS done with 10 minutes of prep, and the presentation of the written is a presentation of your BS skills.

Someone please teach me the art of BS - I need to BS my way into states :sob:
How do I BS for 7 minutes straight with only 10 minutes worth of prep?????
