Add a way for parents to revert to a lower setting when they see that the current level of difficulty is frustrating their child.
Add a section under the report card to revert to the previous level for another cycle when they see their child is becoming frustrated and discouraged at the present level. Giving them time to practice without that frustration.
I agree, my two year old has been moved to the 4 year old memory level. He gets frustrated, and then stops playing. I wish I could just move the level back so he is still challenged, but not frustrated.
