- Any course for which a student has received a grade of F or NC may be repeated. In such cases, the second grade earned in a repeated course does not replace the previous grade of F or NC and does not erase it from the transcript. Both the first and the second grades will be calculated when computing the student's grade point average.
- A student who has passed a course with a low grade may wish to take the course again, especially if the course is one in a sequence, e.g., CHE 121 or GER 102, where a solid command of the material in the lower-level course is essential for success in the higher-level course. The simplest way for students to repeat course material is to retake the course as an Audit (see "Auditing Courses" ). In special cases a student may wish to repeat a course for credit and grade. Unless the course specifically states in its description that it may be repeated, e.g., ART 291 or BIO 485, the student must first petition the Academic Standing Committee. The original grade earned remains on the transcript and is not replaced by the subsequent grade, as in . A repeated course does not gain the student an additional course credit toward graduation, unless the course description indicates that it may be repeated.
- Adjunct courses, music lessons and music ensembles are exceptions to the above rule and may be repeated every semester unless it is stated otherwise in their descriptions.
- Students who have received credit by examination or transfer will lose this credit if they take a course at Cornell that is the same as or similar to the examination or transferred course. In general, all introductory courses in the same academic discipline are considered to be similar even though their titles or actual contents may vary. Students who believe that their two courses are significantly different should consult the department chair for permission to receive credit for both.
