*Courses taken during the "Away Experience" cannot be substituted for track requirements but can count toward electives.

Electives: THREE additional courses at the 100-level or above are required. Electives allow students to personalize their Earth Systems curriculum by pursuing higher-level courses offered in their focus area, or by incorporating new academic perspectives. Each must be a minimum of 3 units and approved by an advisor.
