Instead of changing the exam week, I'd vote having the 12th week being the week break of school like how real schools have summer vacations.

We already get balls/dances every year on WoP. And the Yule ball is during the winter season.

The hunter faction is equivalent to the Gryffindor house so you have to come up with answers that match that. The Mega Coven is equivalent to Slytherin. So both factions can be aggressive just one thinks for themselves and magic while the other is about killing monsters and saving people.

I easily forget as well, but you can look at how much money you want to deposit by clicking on your FC on the top right corner so you don't necessarily need the deposit all button.

I really love this idea and it would make it realistic since everyone does have birthdays at different times in the school year.
