That is the last of the video-based lecture format for this semester. In week 12, we'll be looking at some revision and doing a live lecture. Please rate your learning experience in the format of the subject since week 7 using video playlists accompanied by notes and quizzes, with 1 being the lowest and 5 being the highest. Sorry about the randomised ordering of the answers -- this is a Canvas setting :)多项选择题
