<p>It's been 30 years, but I knew a guy at Cornell who had received a "likely" letter from Princeton, his first choice, then received another letter saying the first was a mistake, that he was actually a "high probable." I believe he was waitlisted, then ultimately rejected.</p>
<p>I knew someone else who had received an "unlikely" letter at Yale, but was ultimately accepted. (He was a 8-generation legacy; that may have made the difference.)</p>
