In the system I am working on, players choose their level of education during character creation. This education is generally broken down into two categories -- Schooling (i.e., more formal education) and Training (i.e., informal education or apprentice-based work) -- which each have five levels. Right now those levels of named "None", "Low", "Medium", "High", and "Magical". These are awful names, but I am having a tough time coming up with a good theme for what the names should be. Would love some brainstorming from the group.

EDIT: This is more an ask for levels within an education/training system rather than how skilled someone is at a thing. For Schooling -- and this is not the direction to go because it's a bit too modern -- might be None, Primary, Secondary, College, Graduate. It's more about the intensity of their education during a character's younger years.
