u/Time-is-relative

As said in the title, there are a lot of jokes that all the house leaders started attending at the same time, but in the game there's no reference to that (that I can find at least.)

Personally, I think Garreg Mach accepts students when they're 16, and they "graduate" when they earn an advanced class. With exceptions for younger students due to unique circumstances (Lysithea is a prodigy and Petra is a foreign student)

Does anyone else have any theories on why Garreg Mach works the way it does? It doesn't make sense to me that they all start at the same time, especially because a lot of them have established dynamics at the start of the game.
