<p>It’s impossible to pin down, and really, most colleges probably have the same basic criteria that “fit” their profile. There’s not really anything you can add to your profile that will make you a better “fit” for a school- it’s basically AdCom’s judgment of if your personality (and activities) fit the image they believe their school has.</p>
<p>I’m not sure what exactly you are asking, but in my opinion, “fit” is something you should be concerned with when you are picking schools to apply to- not when you are creating your application. If you have been geared towards smaller classes/social circles, pick a small college. If you are an artsy person, apply to artsy colleges. Your application will, by default, include the kind of things that make you “fit,” more or less, if you’ve chosen schools that feel right to you.</p>
