RateMyMustang allows you to see the RateMyProf quality and difficulty ratings of any Western University professor directly on the Western University timetable page to help with course selection.
Western University Timetable: http://studentservices.uwo.ca/secure/timetables/mastertt/ttindex.cfm
-> Due to RateMyProf's lack of public API and ability to query by department, it is not perfectly accurate (i.e. if there are multiple professors with the same last name who teach at Western, you'll get the rating for the first one listed in RMP). Double check by checking the prof name to be taken to their RMP page. Fix is in progress!
