This extension lets you look up professors on Rate My Professors right on your course website. No need to open a dozen tabs every semester, just highlight a professor's name, enter your school, and Prof It! Other Rate My Professors extensions put professors' scores directly on the course website of a specific school. While that may be convenient, this method cannot and does not support most schools. Now, as long as your professor is listed on Rate My Professors, you can get their scores, no matter what school you go to!
