The flow chart below is for all Math courses numbered below 200. An arrow from the button labeled “Math X” TO the button labeled “Math Y” means that Math X is a prerequisite for Math Y.

If more than one arrow points to the button labeled “Math Y” then any of the courses at the origin of the corresponding arrow may be used as a prerequisite for Math Y.

Clicking on button “Math X” links to a description for that course.
