In chapters 7-9 of Harry Potter and the Philosopher's/Sorcerer's Stone, our theme is simply: "Welcome to Hogwarts". Join us (and Harry!) as he is introduced to his new school, new teachers, a new Hogwarts house and new magic.

Open your books and grab your quills! We've reached the point in Harry Potter and the Philosopher's/Sorcerer's Stone where Harry is now a proper Hogwarts student, attending classes, meeting classmates, and learning all about the castle's mysteries.

Now, we are looking at chapters 7-9. We'll teach you all about the Hogwarts professors, give you a handy guide on the Hogwarts houses, task you with some challenges around spells and invite you to make Hogwarts house bookmarks and wizard hat keyrings. And much more beyond all that too.

So! Learn how to play our chapter challenges if you haven't seen them before (one for every chapter, naturally) and even build your own Hogwarts house points jar so you can collect house points as you go along. Our next three challenges are ready for you here.
