Take a look through the class calendar here for currently scheduled classes. Scroll between months by using the arrows at the top left of the calendar. Reserve your spot by visiting the class product page and signing up (paying). Classes that have multiple sessions are shown on each date that they occur. When you sign up for multi-session classes you are expected to show up for all sessions.
See the Refund Policy for information on your ability to cancel and when.
Each class description will state the minimum number of students. Sign up with a friend to avoid cancels due to low enrolment.
