My wife took a rider class -same thing. Was rushed through the whole thing.
The bottom line is, I told her after the first day -you are going to figure out if this is for you or not...
To the OP - if she came home pissed and determined -she wants to ride
If she didn't -riding is not a priority.
In either case - get a small D/S and let her go play some at her own pace. You can't go wrong and you can resell easily if it winds up sitting.
