What's a really good discus throw for a freshman girl?

I've thrown 125 before, which is five feet past state qualifying where I live, but does anyone know how that would rank nationally for my age level? I really want to throw Division 1 in college, but I'm not very big (5'6, 140), and I have a friend who's also a freshman who throws 145. Is she just really good, or am I actually that far behind the best? Do I have a chance at throwing D1?
