Open Water Class Size

[g1138]

AFAIK, they are all OW students except my friend who was certified 20+ years ago and hasn't dove since. She is paying the full OW course price. I also just found out that the class is at different stages of instruction. They started out together but due to the scheduling, everyone couldn't make all the classes. So in a session, some students have only had one class while this is the 3rd or 4th class for others. Some have also had an open water session before completing the pool work.

Sounds like a break in ratios. The OW before completing pool work may have been the Skin Dive/Snorkel checkout, which wouldn't be breaking standards.
It sounds like the Inst:Student are broken though regardless. Even if the ratios were in line it's very sloppy IMO to be teaching a full session catchup because your students are at different stages of the skill curriculum. Like others have said it leads to some students being very bored with lots of down time.
