Help Me Narrow Down My List

<p>My sister came home yesterday, and she helped me do a lot of trimming. Here's my new list - do you think its well-balanced enough?</p>

<p>really reaching:
Princeton</p>

<p>a reach, but shouldn't be too bad:
Dartmouth
Columbia (where my sister goes. I mentioned I hate big cities, but I promised her I'd apply, though I really have little intention of going)
Georgetown
Duke</p>

<p>I should get in, but theres always a chance for things to go wrong:
Wellesley
BC</p>

<p>Safety:
William & Mary
Richmond</p>

<p>I tried to create a pretty even spread of schools across my different chances, do you think I succeeded? I am a bit worried there is too big a gap between Duke and Wellesley, and was considering adding either Tufts or Rice (on jym's suggestion) in between, but I really don't want to apply to too many schools. My limit was 10 (with Scripps and Yale already applied to) though I added Columbia as an 11th at the last minute. Thoughts?</p>
