Cheerleading? Dancing Devis?

Hi, I am a new incoming freshmen student at Duke. And I want to join either Duke Cheerleading or Duke Dancing Devis. I would like to know how many tryout students do they join each year and their levels if anyone know about it. Also do you think is it possible to pass the tryouts of cheerleading without tumbling skills but good at dancing, side chats and so on.

Thank you!
