Uuh, well I hate to tell you this but. . .if you're playing it on PC, then you kinda waste most of your time, and so did I. I switched to mac and found out that the progress increases. On PC, it seems like there a glitch or bug, if you have paid attention to the "leaderboard" of Gryffindor NOT being on the lead, Hermione Granger will say "Gryffindor is on the lead, I do not need to do this", but that's not true, so therefore, the "leaderboard" is bugging, not even resetting it works. This is weird, very weird am I right? So yeah, mac works.
