It sounds wonderful either way that you are pursuing this. I can't decide this for you but let me see if I understand this before I ask:

The one class is $1000- call it Pointe class.
- Age difference
- Scheduling issues
- 4 classes x ____weeks? = ______ how many classes for $1000

The other class is $130- call it Adult class.
- Adults
- No scheduling issues
- 10 classes --->
# of classes for Pointe/10 x $130 = _____equivalent # of classes cost

You are already taking the Adult class and are not getting out of it what you want? The cost is easy to figure out above. If you can do the trial Pointe class to gauge what it is like, I say go for it, try it and it may be just what you had in mind. So worth it and the rest will fall into place.
