I put 4 stars instead of 5 because of the glitches. I am a little disappointed. I am almost finished with the O.W.L.s and I finished the 3rd part of the last section and I waited 5 hrs like it said I would need to. I get on the next day and it took right back to before the 5 hrs and now I can"t finish the O.W.L.s because there are only a few hrs left before the time is up. I'm not asking for compensation but I would like another chance to complete it
