<p>Just a quick question regarding the spring semester. When are classes usually posted on YES to look at? And when do the registration windows usually begin? Thanks!</p>
<p>Later October/Early November is when registration opens. Classes should be viewable well in advance. Some are probably on YES already. Just switch the semester to “SPRING 2013” in top left of YES to view them.</p>
<p>The calendar on the Registrar’s web page says that the Spring classes will be in YES on October 14 and that registration will open on October 28.</p>
