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 Oregon State University’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 GEO 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 GEO 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.
Showing the 57 GEO and feeder courses that have prerequisite links. 68 more GEO courses have no recorded prerequisites. They are listed under Tracks below, not drawn as loose dots here.
The concentrations and majors that build on GEO, and how their requirements are structured. Expand a program to see which courses satisfy each group, then plan it in the Planner.
