I'm going to be revising how I treat Education in SC3E. Colleges will operate just like accelerated training does in IHW: Wild Blue or IHWSC - you get a group of skill ranks - for the first year, and are able to select from what the College offers or from the Generic College Skill List for the other three years. Graduate education will operate similarly.
So, you take background skills to get to age 18, or take a Template. Go to College if you want. Take an advanced degree if you want. Get into a profession. Switch professions if you want. Stop when you are ready to play. Makes things a lot simpler, and keeps non-military professions more on a par with the military professions skill-wise.
