<p>I’ve hated my chem professor who had a smiley face rating and liked my chem professor who had a sad face rating. The site isn’t perfect. When multiple people are saying the same thing, it’s usually accurate. When there seems to be conflicting thoughts on the professor, it’s hard to tell. Also take into account the number of ratings they have. Don’t not take a professor if they have 3 ratings and 2 of them are bad. That means little out of the hundreds of students they have taught. I trust the CAPE evaluations more, but I still use ratemyprofessor.</p>
