you become sirius and you battle death eaters and then you become dumbledore and you battle voldemort and you become harry and voldemort tries to get into your mind and you have to use occlumency to stop him which is just pressing lots of buttons without missing any for 1-3 minutes and it takes you back to hogwarts and you can finish your extra classes thing but you cant leave the common room and you cant see the pictures you collected and you can only start again =[
