Two Google tabs remained open as I decided classes for pre-enroll last semester: the class roster and ratemyprofessors.com. At times, a class’s number of credits or time slot can take the backseat to a detailed professor review. For those unfamiliar with the site, the typical instructor profile almost always features several near-perfect reviews towards the top. Naturally, you’ll ask yourself how these professors are receiving overall ratings of 3.5/5. The answer lies a few scrolls below, buried in the pop-up ads.
