Common Ground Subjects
What Are Common Ground Classes?
Common Ground classes blend computing with other fields students are studying. Think of them as bridges between computing fields like computer science and your major, whether that’s biology, economics, architecture, or literature.
These courses help you become “bilingual” in both computing and your discipline. For instance, rather than just learning programming separately, you’ll learn how computational tools and thinking apply directly to another field such as your major. This is increasingly valuable since almost every discipline now uses advanced computational methods.
How to Spot Them
Look for the “.C” in course numbers. For example, 9.C20/16.C20/18.C20 (Introduction to Computational Science and Engineering) shows that four departments collaborated on this course. The “.C” is your signal that it’s a Common Ground class.
