When signing up more than one child, make sure to change the "Qty." (Quantity) 

Advanced Soccer clinics are designed for players who are not beginners and already have a more than basic understanding of the sport. You are required to describe your child's experience with the sport when registering. A coach may call you for more description if they think your child's experience level may not be at the required level for the class, and they may have your child switch to a non-advanced class if they do not have the experience required for the class.
