Courserank [korz·rank] n. archaic an early course-ranking platform (software), originally created as a class project by a Stanford student; sold to Chegg, Inc. in 2010 but the company eventually shuttered the project.
NOTE: After the demise of Courserank, several alternative "course rating resources" sprung up in an attempt to fill the void it left. Not all of these survived. The current university developed tool, Carta, is one of these progeny. --Ed.
