3. Substitutions

A. A course in statistics, as approved by the Chair of Undergraduate Studies, may be substituted for BIOL 243 in Core 1.F.

B. ENSC 502 may be substituted for requirement 1.N. and a further 6.00 units in electives and/or Plan requirements as approved by the Chair of Undergraduate Studies.

4. Notes

A. Students are strongly advised to complete all requirements for 100- and 200-level courses in their first and second year, paying special attention to prerequisites and corequisites needed in 300- and 400-level courses.

B. BIOL 206 is highly recommended as it is a prerequisite for upper-year Ecology courses (e.g., BIOL 300, 323).

C. A maximum of 6.00 units from courses offered by other Faculties and Schools may be counted toward the program and/or Plan requirements. This includes courses in BMED, COMM, GLPH, HSCI, LAW, NURS, and courses in the Faculty of Engineering and Applied Science.
