Registration Day(register for classes) is one of the most important days in college. The registration starts at 7am. This means more than thousand studend is logging on to the school website to rigister. If you are slow, you are very likely to get waitlisted.
Today, when I log on to Facebook around 10:30am, I saw 3 of my firends on the first 10 "top news" complain about being waitlisted. "A stressful process" as one of them stated.
