At a crossroads and need some opinions?

I signed up for a dance cl. A hip hop cl at the local junior college! And it would last for 4 weeks! and it was on Tuesdays! But, the teacher rescheduled it to be on Wednesday nights. But on those nights, I am very active in my youth group at church. Now, what do you think I should do? Go with my pion of dance and just miss out on church? Or go to church and miss out on dance?
