Course materials, slides used in the class, assignments, group activities, quizzes, references, syllabus etc. are regularly uploaded under respective course categories in a Learning Management System (LMS) maintained under https://canvas.instructure.com. Students are requested to check their respective course homepages for new uploads by logging in to the LMS. The ways to join a particular course are discussed in the class, generally, at the beginning of each course. If someone misses that, he/she may contact the course instructor.
