Building the department map…
Department paths
Courses with no prerequisites inside the department that unlock the most downstream work.
The shortest canonical route from each entry point to a gateway course.
Generated from University of Toronto Faculty of Arts & Science’s catalog, prerequisite, and concentration data. Spotted an error? Departments can adjust labels, ordering, and notes without a code change, so contact us.
Each of these unlocks the largest share of downstream work on this map. Courses from other departments can appear here when they genuinely gate CSE coursework.
Intro tiers at the top, advanced work below; arrows point from a prerequisite to the course it unlocks. Courses from other departments appear where they gate CSE work. Click any course to see what it requires and unlocks without leaving this page; hovering lights up its neighbors. The lists on this page carry the same courses in text form.
