Well taught unit with a very clear reading guide. However, the slides often did not have much information and limited practice questions were given. Although, answers were given to the questions in video form. The lecturer is super lovely. It is an interesting unit but 40% of your grade comes from an online test which is quite difficult. The content, while interesting, is difficult to piece together neatly compared to other units, especially as it keeps changing due to reforms. Do this unit if you are interested in the topic but it is not an easy D/HD.
