Thanks, ericl! She is doing this to supplement school (no acceleration is available until they reach a higher grade, although she is "on-track" according to her teacher to get into accelerated math), so I am just wanting her to maximize her time.
She is in quite a few after school activities, so she won'l always have extra time to use EPGY (since it is in addition to her regular math coursework).
I did contact the "contact person," but her child is no longer in EPGY, so she cannot help me.
She did over 450 problems yesterday and got 99% correct - my idea with EPGY was to enrich/challenge her in math a bit more. It doesn't seem very challenging for her yet, and I don't want her to loose interest. Hopefully, as she moves up, it will be more challenging for her.
