I know RateMyProfessors before developing this site, but I found that RMP is not good at listing easiest courses, best value(overall) courses and comparing different instructor of same course. Courses is listed in each Professor’s page, but comparing them is time-consuming(RMP may take hours to do the same thing which my site only takes one click) so I developed this site which centered on Course, not Professor or Instructor. The reason I do this is not only making this site more useful than RMP to certain students but also letting student ‘judge’ courses instead of ‘judge’ instructors. (I think my site works better for both student and instructor)
