Yes I did the class - I booked a room in the local library. The class was very straight-forward and very helpful. I contacted the rep a few times after the class so make sure you get their contact details
I think your doctor should provide some initial omnipod settings to you in advance based on your current doses and logs etc.
I think the first part of what the rep went over is covered in the tutorials below - I found them really helpful and watched them a lot in the beginning. They are well done and just 1-2mins long.
Definitely worth taking an hour and watching them in advance.
POD settings was the other part. It is summarized here. This is essentially to setup how much insulin basal your daughter will receive in each hour. And Secondly how much bolus she would get (Carb-Ratio) at different times of day
