Program and plan requirement checklists

1. Calendar Year: The default calendar year is the one in effect when you started in the Faculty of Math (to which CS is a part of), although you can choose a more recent one. For example, if you started in Math in Fall 2020 but joined CS Fall 2022, then you can use the 20/21 calendar and any calendar year after that. If you started in Engineering Fall 2020 but joined CS Fall 2022, then you must used the 22/23 calendar year instead. Students pursing a double major students can use different calendars for each program.

2. Required Courses: For "required courses", each course can be used to fulfil at most one requirement.

3. Additional Contraints: You can use a single course to satisfy more than one constraint. As an example, you can use three courses (PSYCH 101, PSYCH 211, and PSYCH 312) to satisfy the breadth requirement (1.0 units from the social sciences) and to satisfy the depth requirement (1.5 units with the same prefix forming a prerequisite chain of length three).

4. To save space, a requirement such as “CS 115, 135, or 145” is abbreviated as “CS 1[134]5”.

5. Math Courses: Math units are courses offered by the Math Faculty (e.g., ACTSC, AMATH, CO, PMATH, STAT, etc.) except for COMM and MTHEL courses, plus a set of math-intensive courses offered by other Faculties.

6. Breadth and Depth: To fulfill the Breadth and Depth requirements, you'll need to take courses in certain subjects, such as "1.0 units from the humanities". For information on the subject areas, see "Elective breadth requirements" in the calendar. 
   
   You can count a non-math course towards both Breath and Depth requirements. For example, if you pass ECON 101 and 201, then you've satisfied 1.0 units of the Social Science Breadth requirement. If you take ECON 301 after, then ECON 101, 201, and 301 satisfy the Depth requirement. Go to the Breadth and Depth page to find a list of courses you can use to satisfy this requirement and which category they fall under.

7. Non-Math Courses: Non-Math units are courses that must be offered by Faculties other than Math, plus COMM and MTHEL courses. In other words, these courses must not be Math courses.

8. Depth Requirements: To satisfy the depth requirement, you can use 1) three courses or 1.5 units with the same prefix where at least one of those courses is 3XX or higher (e.g., ECON 101, ECON 102, ECON 344).
   
   Or, you can use 2) three courses or 1.5 units with the same prefix that form a prerequisite chain of three. A prerequisite chain of length three is created when course Z has course Y as a prerequisite, and course Y has course X as a prerequisite. For example, you can use PHYS 111, PHYS 112, and PHYS 224 to satisfy your depth requirement since you need to take PHYS 111 before you can take PHYS 112 and PHYS 112 before you can take PHYS 224.

9. Elective Courses: Electives units can be fulfilled by taking Math or non-Math courses.

Note: For more details, see degree requirements for all math students or the academic plan requirements for Computer Science programs.

Note: Some courses are cross-listed and have different course prefixes (e.g., PHIL 205 is cross-listed with ECON 261). Cross-listed courses can count as one subject or the other, but not simultaneously both when completing your degree requirements.
