Where have Friday classes gone? Students have noticed fewer classes on Fridays, and while some professors say their departments aren't changing, others say changes are being made to their schedules. The science department still prefers to teach Monday/ Wednesday/ Friday classes, chemistry professor Lisa Gentile said in an email response, but other schools such as the Business School and the Jepson School of Leadership Studies have seen changes over the last few years. There have been several factors that have led to fewer Friday classes, most notably a scheduling overhaul that goes back several years, said Bob Nicholson of the Robins School of Business. Just before the 2008 fall semester, Richmond changed from a credits system to a units system, he said.
