Absolute Beginner: You've never touched clay before. You would best be suited to an Introduction to Throwing class but you will also do fine in any Beginner/Intermediate class. 

Beginner-ish: You have some experience with clay. You are best suited to any of our current classes. 

Intermediate +: Our Wednesday 2-5pm slot is aimed at providing space for our more experienced potters. However, with our small class sizes and excellent teachers, you'll do fine in any slot. Just discuss your needs with the instructor.
