Like what school would things like Conjuration and Transmutation fall into?

It seems like it would depend on what you're trying to conjure or transmute. Summoning an elemental usually falls under the associated element. Transmutation might be more Universal, especially if you're able to transmute between vastly different things. Turning lead into gold is probably just Earth magic, but it might require Earth and Water magic to transmute lead into wine.

That's just my guess based on how conversations have gone so far.
