Should i tryout for cheerleading if i don't have the skills?

I'm transferring schools (different states) and the new school says to be considered I have to have a standing backhandspring, toe-touch backhandspring and roundoff backhandspring minimum. I really wanted to take cles for tumbling and stunting during the year but lacked transportation and now I'm moving in with my mom and will be able to take cles. The thing is I only have a month to prepare for the tumbling and stunting portion, so if I don't have the skills by tryouts should I still tryout or would I be wasting my time?
