bCourses (https://bcourses.berkeley.edu, also sometimes referred to as "Canvas" - this is the name of the mobile app) is the course management and collaboration environment on campus. The majority of classes in the law school use bCourses for things like course materials, announcements, media links, assignment submission, and web collaboration.
For further support, use the Help menu on the left side of every bCourses page. There are guides and resources located there as well as many different ways to report problems or request support. The campus bCourses support team will direct any questions they cannot answer back to the law school support staff.
Cal Central (https://calcentral.berkeley.edu) is a site designed to pull notifications and information from all your different personal campus resources (bConnected, bCourses, billing/financial information, etc.) into one easy-to-view location.
