Very bad experience taking this subject. The lectures (pre-recorded) are only 15 mins per week and the lecturer just reads out the slides. The slides are highly repetitive and not very informative. So the 15 minutes lectures are pretty useless too. You can get good grades provided you do a lot of self-learning using resources from google (the canvas reading resources are hopeless for this subject). So my final say: Don't waste your money on this subject, you'll have to do the learning by yourself anyway (from google resources). There are so many other well-taught units/electives. Please be wise and opt for any one of those.
