The Google Doc is categorized by department. So, if you're taking ENST200 (Soils) for example, and you want to study with someone else who is taking that course, click the ENST tab at the bottom, find the course (you may need to add a course yourself) and add your name and contact info. Hopefully others will sign up, too and you can connect!
