I was looking on the lexicon for what classes various houses had together. This is what I know:

  • The Slytherins and Gryffindors have DADA, Care of Magical Creatures, and Potions together.
  • The Gryffindors have Herbology with the Hufflepuffs.

What classes do you think Hufflepuff and Slytherin have together? Do you think the class pairings change by year? For instance, one year, would the Hufflepuffs have a class with Ravenclaw, but then the next year have it for Slytherin. In addition, for the NEWT classes, do you just have it with everyone, from every house, who has that NEWT?
