What information about me should I give to those doing my recs?

<p>Hey everyone!
I asked a teacher and my guidance counselor earlier this week if they could fill out the Common App recommendation for me, and they both agreed. To help them fill out the forms, they both asked for something along the lines of an "autobiography." I'm okay with that, but I find it a bit vague. Has anyone else been asked for something similar?
My guidance counselor does not know me that well at all. I go to a big school, and there's only three counselors for every student, so it's safe to say that they hardly get to know anybody. Also, I looked at the form my guidance counselor will fill out in PDF format, and it honestly didn't look like she had to answer a whole lot about me. I'm still fine with giving her something, but just how much should that be?
I know these are questions I could easily ask both the teacher and the guidance counselor, but I don't want to feel like I'm bothering them, so I thought I'd ask here first. Thanks everyone!</p>

<p>Maybe this form will feel more like what you want them to know.</p>
