The discussion centers on the policy regarding retaking calculus courses at various schools, particularly for a student who earned a C in Calculus I but excelled in subsequent courses. Most schools typically allow students to retake a course only if they receive a failing grade or a D in their major, and many do not permit retakes for grades of C or better. Retaking a course to improve a C is generally seen as unnecessary, especially since the student demonstrated proficiency in higher-level calculus courses. It is suggested that the student focus on advancing their education rather than retaking a course, as doing so could negatively impact their application to graduate or medical schools. If the goal is to strengthen understanding of the material, self-study is recommended instead of pursuing a formal retake. Ultimately, checking specific school policies is essential for accurate guidance.
