Are the student reviews on rate my professor true? If so, they are horrid.

Can someone who is an actual student comment, see link: https://www.ratemyprofessors.com/school/927 Most are saying school is impossible to get higher than B's and they force you into their intercession courses. Once you pay you are stuck and the professors don't care. Someone tell me this isn't true. This is not the picture we saw at the tour and Destination SMU.
