  2. Students aiming to meet the academic requirements for professional registration of Geoscientists (PGeo) in Ontario can find additional information on these requirements on the website: https://www.science.mcmaster.ca/geo/undergraduate/undergrad-welcome.html. Students are encouraged to consult with the academic program advisor in the School of Earth, Environment & Society to ensure proper selection of courses for professional registration. The Honours programs offered by the School of Earth, Environment & Society may not fulfill professional registration requirements.

  3. There are Level II prerequisites for many Level III courses; these should be considered when choosing Level II courses. As an aid to choosing a coherent set of courses in a single discipline, students should consult the list of thematic areas applicable to all Honours Earth and Environmental Sciences programs.
