But why do you let the students grade the course after they've already gotten a grade? That's insane. In my university, you'd get a paper for the teacher and course review after handing in the final exam. This means you can comment on the quality of the exam, but you don't know your grade yet.

Theoretically, if you grade students several times throughout the course, you can correct those who are on course for a poor grade (due to misunderstanding the content, or misunderstanding how much studying they need to do) while there's still time for feedback to improve their grade.

(At my school many teachers were slow to mark and return assignments, so this benefit wasn't really achieved - but it might have been had feedback been more timely)

Then make your exams very easy so the students will be in a good mood when they fill the teacher and course reviews.
