I’m really sorry but I’m currently in the middle of GCSEs and don’t have much time- I’ll try and update soon but I can’t promise anything….
OK so before I do the rest of the chapters, I’m going to go through my old ones and tag them with the names of all the items found in them. That way, if you want to know where to find an item, you should just be able to type in its name and all the chapters in which it can be found should come up :)

Helpful HInt: I, too, found myself locked out of Book 3. Because I am a Slytherin, I did not have to brew the Polyjuice Potion in order to enter the Slytherin common room. What I discovered was that I needed to buy the necessary books in Diagon Alley before I could continue to Book 3. Hope this helps!
The past two posts were submissions- so remember- if there’s anything else I’ve missed, send me one! :)
also, on moment 2 of chapter 13 at the end of the bench, second from the left, theres a stack of five galleons, on the end closest to the teachers table, and the cupids.
Have you made the polyjuice potion? That may be holding you back if you haven’t. If you have, then it could just be a glitch, in which case try clicking this link to access it: http://www.pottermore.com/en/book3/chapter1
book 2 chapter 10.1.2 in the bin along with the two bertie botts beans, there is a chocolate frog card
