## C O M P U T E R S C I E N C E

### Notes

- The phrase "Computer Science students" refers to students enrolled in any honours plan offered through the David R. Cheriton School of Computer Science. Software Engineering, Computing and Financial Management, and Bachelor of Computer Science (Data Science) students are considered Computer Science students. Students enrolled in the BMath (Data Science) plan are not considered Computer Science students. Due to course restrictions on upper-year courses, students pursuing a Computer Science Minor may need to enrol as Computer Science students for part of their undergraduate studies and should contact a computer science (CS) advisor for more information.
- First-year CS courses are available to all students with the exception of CS 100, which is not open to Faculty of Mathematics students and most Faculty of Engineering students, and CS 137 and 138, which are only available to Software Engineering students.
- Upper-year CS courses are divided into two streams.
- Courses with middle digits 4 to 9, e.g., 350, are designed specifically for Computer Science students. Some courses are open to all Faculty of Mathematics students, but most are restricted to Computer Science students only. BMath (Data Science) students are eligible to take all CS courses listed as required or elective for their plan, as detailed in individual course descriptions below.
- Courses with middle digits 0 to 3, e.g., 230, are designed for a broader audience, including students pursuing the Computing Minor. These courses are not available to Computer Science students.
- In exceptional circumstances, student who are not Computer Science students may be allowed to take restricted CS courses. For more information, students should contact a CS advisor. Engineering students are not usually allowed to take restricted CS courses that have an Engineering equivalent available. When space is limited for restricted CS courses, Computer Science students are given priority.
- Computer Science relies on student course selection data to determine the demand for courses. Every effort is made to accommodate students who choose classes during the Course Selection Period, though space may be limited for some courses. Students who do not course select may be unable to take their preferred courses.
- The terms in which courses are offered may change. For up-to-date information, students should check the Schedule of Classes.
- A CS course may not be taken for credit if it is the prerequisite of another CS course that has already been passed.
- Students who have demonstrated exceptionally strong academic performance can take graduate-level courses if there is enough space and they get approval from both the instructor and a CS advisor. Undergraduates are not allowed to enrol in 600-level courses when an equivalent 400-level exists.
- An enriched version of a CS course, with an "E" suffix, may be substituted for the regular version of that course in any plan requirement or course prerequisite, or for any other Calendar purpose. Whenever a CS course is an antirequisite for another course, the enriched version is also an antirequisite for that course. A student may not receive credit for both the enriched version and the regular version of any CS course.
- Undergraduate students who take graduate courses that do not count towards their undergraduate degree can sometimes use these courses to satisfy graduate study requirements. For more information, students should see the Accelerated Master's in the Computer Science section.
