No, when purchashing a session you are purchasing 8 weeks for that particular class. So, if you enroll for the 8 Week Beginner Ballet Session, you must take all 8 weeks in ballet. You can't, for example, take 2 Beginner Ballet classes, 2 Beginner Jazz classes, one Beginner Hip Hop etc. You are however allowed up to 2 make up classes. These makeup classes can be taken in other generes than what you origanlly signed up for.
