Student Advising

  • If you would like to book a student advising session, please go to the Academic Advising & Orientation section of our website or email undergrad.micromimm [at] along with your McGill ID number. 


Important Information

  • Once registration is open: If you need permission to register for a course that is outside of the MIMM program, you must contact the department where the course is given. If you are a MIMM student and wish to register for a MIMM course within the required course list and they are full, please email undergrad.micromimm [at] along with your McGill ID number.
  • Passing Grade: All REQUIRED and COMPLEMENTARY courses listed in your program must be passed with a “C” or better. “D” is a failure. If you receive a grade of “D”, this can be considered as one of your electives and then you can choose another complementary course from the list.
  • Complementary Courses: are REQUIRED and count towards your program requirements. You must choose a specific number of credits from complementary courses in order to complete the program requirements.
  • Electives are courses that you take outside of your selected program, in order to reach the 120 credits necessary for obtaining your degree.

  • S/U Option: You may choose to have a final grade of S (satisfactory) or U (unsatisfactory) for one of your elective courses. This option cannot be used for required courses, including complementary courses. The decision to have an elective course graded as S/U must be made before the end of ADD/DROP.
  • Failed a REQUIRED course? You have two options:
    • Apply to write a supplemental exam or
    • Repeat the course
  • If you fail a COMPLEMENTARY course or receive a final grade of “D” you have three options:
    • Apply to write a supplemental exam or
    • Repeat the course or
    • Since a D is a pass for an elective, you can choose another course from the list.
  • Thinking Ahead: Applying to Medical School
    • Students who wish to leave the option of applying to medical school should be aware that they can choose to complete any of the Science Majors (not only the biological or life sciences ones). Most medical schools look for a diverse applicant pool, and all of the Science programs provide ample room to include medical school prerequisite courses. For more information, visit:
