Each term Submitty is used by 2000+ students in 15+ courses in the RPI Computer Science department. The courses using Submitty cover the undergraduate and graduate curriculum from introductory programming courses, intermediate and advanced theory courses, popular junior/senior electives with team projects and written reports, and specialized graduate courses.
