Google Classroom is a free web service developed by Google. Its goal is to make traditional classrooms paperless so that creation, distribution, and scoring can be performed online. Students can join a "classroom" through an invitation code or automatic import. Each "classroom" creates a cloud disk storage space for each user, so that students can upload their work to the teacher for correction. The app provides a collection of nine courses to help you get the most out of Google Classroom.
