Math and hard science learning can be reasonably measured by the kind of objective testing that KA does, however that is inadequate for subjects like history. Knowing about a bunch of events says nothing about the "lesson". I wonder how KA plans to address that, if at all. IMO, it'll be good if KA focuses on the hard basics like mathematics. (By "hard" I don't mean "difficult" btw.)
