<p>You can apply at UIUC to a particular college and program, or you can apply undecided, but it varies by university. At UIUC, you can be denied entry to you first choice program for a variety of reasons. UIUC can then offer you admittance to an alternate program in the same college, a different college or DGS. If they make you an offer at all, that’s a good thing. If they don’t, its a deferral, a rejection, or a waitlist depending on the time of year.</p>
