Age/Year Question

I know that this will probably be the dumbest question I have ever asked, but it's bugging me so much that I have to ask.

Okay so when you first create your character and they want to go to one of the three schools, do they all have to start out as eleven or can they be any age?

If they can be any age, would we have to provide background information for those past years if we want our character to be a full student at that school?

I am so sorry to ask this question, but none of the topics posted have really answered this question and it's really putting me behind from finishing my character profile.

You can start them out at any age you wish, and your character's history will have to reflect that. There are some awesome sheet examples for students here if you want an idea. I can't tell you how much information you need per year, but I'm sure an admin could tell you better.

Thank you so much! This really helped me so much!
