Should I apply to WashU Early Decision?

<p>Hi guys, I’m thinking of applying to Washington University in St. Louis early for two reasons: first and foremost, I really do love the school and feel I would feel at home there, academically and socially. Second, I know that ED increases your chances at WashU significantly.
I also really like Claremont McKenna (where my dad went), Pomona, Brown, and Stanford (where my mom went–I have huge legacy but it’s still nearly impossible to get in).
My older sister who goes to Stanford is encouraging me to wait and apply to all of my reaches in January. She says you never know where you’ll get in. I’m concerned that, with my low SAT math score and my B+ in AP Physics, those schools could be impossible for me. I feel I would be happy at Stanford or Brown, and I would probably choose them over WashU. Should I listen to my sister and wait? Here’s my info:</p>
