What do collages look out for?

I've always ed wanted to go to William and Mary since forever. If I went I would cry my eyes out of happiness. This last freshman year I got An or rolls the whole year. It's not distinguished an or rolls. But it's still very good right? If you could please tell me what I need in order for a good collage like that to accept me. I would love you forever. Please tell I want to know, I really want to live in my favorite place,Williamsburg. :D
