Howdy! Although I do not know much information about the Cursed vaults, this idea seems interesting! You can add this idea to the uservoice for others opinion if you'd like and it'll appear on the PotterworldMC discord for others to help vote on! Awesome idea though! I love exploration quests.

Howdy and Welcome to Potterworldmc! As above has said you can attend any classes as you want and you advance every 10 levels! I suggest doing /faq while in-game to learn more and /nc- which will give you a link to the class schedule. You can also find the schedule here click here. I hope this helps and have a magical time in-game!
