See pp 493-495 of your textbook or any financial management textbook. Proofread your documents. Make sure to modify the financial templates to fit your company. For example, you shouldn't have references to chocolate unless your company actually deals with chocolate in some way. After all the presentations are finished, go through your scoring and rankings and adjust them as needed to produce the ranking that best reflects your willingness to invest money in the new venture.
Different presentations can wind up with the same scores.
After all the presentations I will publish an average score and ranking for all the presentations based on the class evaluations. These will not include my evaluations, which are confidential. Presentations start tomorrow. I emphasize that your presentation should be a sales pitch. You are trying to get venture capitalists to invest in your company.
