<p>Sit down and look at the estimated offers you have. Since verification is going to likely be fine, you can pretty much go with them. I agree that UIUC isn’t anything to hold your breath on. </p>
<p>As for committing to more than one school, you have to look at the applications and agreements that you signed when applied to them. I believe that the common application, for example, does specify that you are agreeing to be enrolled with deposit at one school at a time. Some other schools may not have such stipulations. How strictly that is enforced is up in the air. Some schools specifically state on the form where you accept admittance and send out the deposit that if they catch you double enrolling, your offers to such schools will be rescinded. CMU is a specific exception.</p>
