Early Decision question -- ED Round II @ Tufts

I am considering applying ED Round II to Tufts. Tufts is by far my first choice, however there is something that concerns me.

Lets say that I get in ED, but they give me a bad financial aid package, I mean, bad to the point where my family simply cannot afford to send me there, can I back out simply because I cannot afford it?

<p>Yes, but it will still be a messy situation that won't be easy to let go as with every ED binding process. However, if you do not meet the demonstrated need, the financial aid packages I've heard have been very generous when I asked some of my friends. They do take the ability to pay in consideration in admissions, but once admitted, they take responsibility to help you finance your education.</p>
