<p>After I submit my SIR to the UC I choose to attend, do I have to let the other UCs that I was accepted to know I’m not going or does just not submitting their SIR by the deadline take care of that?</p>
<p>you have to submit your sir's to the other uc's, except you send them a "rejection" sir. i have done this for some uc's already. logon to the site and there should be an option to "decline the offer of admission"</p>
<p>You don't HAVE to decline the other schools. If they don't hear from you by May 1 they'll assume you're not coming. But sending in the negative SIR is the polite thing to do.</p>
<p>What about sending in the SIR and then actually end up NOT going?</p>
<p>PXalpine: there's probably a huge penalty for that.. not sure. you are breaking a contract, they can technically sue you. but who knows</p>
<p>Hmm... I thought all they did was take your down payment on tuition (down payment? maybe... you know what I mean).</p>
<p>BackToReality</p>
<p>but its a technically a contract. even "winning" an ebay auction is a contract... most people don't put in the effort to sue cuz its not worth it but technically you can.</p>
<p>you really have to let the uc's know, or they'll contact each other and ban you from there campus</p>
