This course should the easiest one in the six choices in the Data Science stream [Algorithm and Math] electives. However, I reckon this course is still 4 times harder than COMP9020. In 2020, the lecturer Tom is pretty good as he replies promptly on Moodle. However, if you are not a math student in your bachelor's degree, this course could be pretty fast for you, please prepare well for this course. The 2 assignments were a little bit hard for me (I am a CS student in my bachelor's degree), but I got 38 out of 40 before the final exam. Luckily, I passed this course even though the final exam was so hard, even Math Postgrads also commented like this. I consumed a lot of time on this course compared to the other two ADK in term 1. IT postgrads, please carefully consider whether this suits you or not.
P.S: There was an accident in 2019, that in the final exam many questions were from tutorials, which made so many students got excellent marks. After that, the faculty decided to increase the difficulty in this course's final exam.
