How far in advance do I need to register for class? What's the latest I can register for a class?
You can register for a class until the end of the first week of class. However, our classes are limited to 12 students and our most popular schedules do fill quickly.

Cancellations after that but before the first day of class will receive a refund of the tuition minus the $50 non-refundable deposit. No refund will be given after the start of the first day of class, regardless of attendance.
