We just started the EPGY math and LAW but DD7 is finding it frustrating. The interface is quite primitive and often counter intuitive. I was hoping to push her through that aspect but then one of the math times questions was illogical, which really confused her. It showed "two trays with things" which clearly had no things in them (that was the point of the exercise, to end up with 0) but the first question required her to say there were "two trays with things" in order to answer the others correctly. That was a show stopper for me.
