<p>I was accepted into UCSC and UCR, and ended up going with UCSC, but I got a D in one of my classes, and I know my application is going to be cancelled. So how can I withdraw, so that I can apply to UCR?</p>
<p>I now know what I’m trying to ask, how do I cancel my SIR?</p>
<p>Just SIR to UCR schools and email UCSC that you are formally requesting to withdraw your SIR.</p>
