My dear wizard,

As you may know, the Chamber of Secrets is a hidden room within the Hogwarts School of Witchcraft and Wizardry. It is said to be the home of a dangerous creature, and only the heir of Slytherin can open it.
Before you can enter the Chamber of Secrets, you must show your intelligence by answering a set of questions...

Maybe you can help?

Sincerely,
Albus Dumbledore
