You may select or cancel the S/U option only during registration or the add/drop period through a request to the BCom Student Affairs Office. All S/U credits will be excluded when calculating the Grade Point Average. This option may only be used for elective courses, one course per term, to a maximum of 10% of the total credits taken at McGill to fulfil your degree requirements. Careful consideration should be given before using this option as it can affect scholarship and award consideration, where a minimum of 27 graded credits are required, as well as future admission to law or graduate schools.
For more information and restrictions, refer to Programs, Courses and University Regulations > University Regulations and Resources > Undergraduate > Registration > Courses Taken under the Satisfactory/Unsatisfactory (S/U) Option.
