I reckon it can and I am about to give it a shot, myself. It sounds like a Duolingo sort of structure, which can be boiled down to "use it or lose it" which is not hard to support with compelling evidence. Say what one will about Duolingo, but my Spanish and German are passable because of it (no, I am not fluent, but I can get by in common situations). Ideally, MathAcademy will cultivate the same results.
