2020 Academics: The Details

For those who would like to dig into the details of the class archives, these PDFs are for you. Here is the chart of Prerequisites, a set of related classes we call Clusters, and, to help you visualize them in a different way, Cluster Conflicts.

We post schedules and course descriptions ("blurbs") each week throughout camp. Here are the 2020 classes:
