QCS: Course Materials and Schedule
Lecture Recordings
All lecture recordings should be accessed via Learn; you will need to log in using your EASE account. (Learn provides you with access to any lecture recordings available for this course. You will need to select the "lecture recording" link once, before you can access any direct links to a lecture recording.)
Reading References
Lecture notes are the first thing to study and are suppose to be self-contained. However, further reading and details are given below.
