Another Pottermore Frage

This probably gonna be an ongoing thing with me asking questions, until I get the hang of the Pottermore website.
But I'm wondering, how do Du advance to the Sekunde book? I have finished the first book and JK Rowling sagte her congrats and whatnot, but I can't Bewegen on; I'm still stuck on the last chapter of book one.
Is there something I have to do first, like gain Mehr house points oder something?
