Numbering of Courses
Courses numbered from 001 to 009 are pre-university level courses offered at the discretion of the Department, and are primarily intended for students who do not have Ontario 4U or equivalent standing in the subject. Unless otherwise indicated, these courses are offered for credit as electives in any degree program.
 
Courses numbered 010 to 099 are intended primarily as electives and normally do not lead to further courses in the subject, unless under special conditions laid down by the Department.
 
Courses numbered 100 to 199 are introductory courses, normally taken in first year. They may be differentiated by method and/or intention, but all lead to further work.
 
Courses numbered 200 to 299 are normally taken in the second year and usually require a previous course in the subject. They are standard second-year courses for all concentrations.
 
Courses numbered 300 to 399 are normally taken in the third year and have prerequisites determined by the Departments. They are required in the third year of four-year programs, but are not necessarily required in three-year programs.
 
Courses numbered 400 to 499 are normally taken in fourth year and are primarily intended as senior courses in the four-year programs. However, they are open to all students who meet the prerequisites.
 
Courses numbered 500 to 590 are reading or undergraduate thesis courses.
 
Courses numbered 591 to 593 are general examinations in the honours programs.
 
Course numbers for independent study include the following: 594* - 0.5-credit course; 595 - 1.0-credit course; 596/2.0 - 2.0-credit course; 597/3.0 - 3.0-credit course; 598/1.5 - 1.5-credit course.
 
When a course number is changed, the former number for the course will appear under Exclusions following the course description for five years subsequent to the change. Students who take longer than five years to complete a degree program are advised to consult departmental academic advisers to ensure that the courses they select do not duplicate work previously completed.
