Retake a class with a grade of C or better?

<p>I want to retake my Physics 1C class because despite earning a C, I felt that I wasn't proficient in the material and I would be unprepared for the upcoming Physics 17. However, the policy is that you can't retake a class that you have earned a C or better in. Are there any exceptions to this rule? Should I talk to a counselor or some other people?</p>

<p>I do not believe there are any exceptions other than ask the professor to lower your grade (which some refuse to do).</p>
