  • Fall, Winter
  • Restrictions: This course cannot be taken under the S/U option. Departmental permission required. Students cannot be supervised by the same instructor for two 396 Science courses. Open to students in programs offered by the Faculty of Science only. This course must be taken as an elective, and cannot be used to fulfill program requirements.
  • Note: Enrolment may be limited. Students are advised to start the application process well before the start of the term and to plan for an alternative course in the case that no suitable project is available. Individual projects may be suggested each term which may have project-specific prerequisites. Students may also approach professors to devise their own projects. Some projects may be accessible to students in other disciplines. See https://www.mcgill.ca/science/research/undergraduate-research/science-re... for more information about available projects and application forms and procedures.
  • **Although this is a project course from May 3rd until August 31st, it does not follow the standard add/drop and withdrawal deadlines. Therefore, add/drop is July 1st and withdrawal is July 22nd.
