What is the difference between Group, Private, and Private Group classes?

Group classes are available to multiple students (up to your set maximum) and are generally given at a time set by the teacher.  For example Tuesdays at 10 am. 

Private classes are one-on-one. The teacher will meet with an individual student and generally there is more flexibility for students to choose from a range of times since the classes are individual. Users can also send requests to teachers for a specific time.  Many teachers will offer rangers of time for private classes to give the students the flexibility to choose. Example : Mon - Fri: 10am - 6pm.  

Private group classes can be requested by sending a message to the teacher using the "chat with me" button on the class page to request a private class with a group, such as a birthday or a team event.
