I really enjoyed this subject. I've never studied politics (formally) before and I really regret it. They cover a wide array of topics covering post-1945/WWII, with a focus on Eastern vs Western ideology (Capitalism vs Communism) as well as revolutions/oil etc. There is only 1 lecture per week and the lecturers are quite good and interesting. The lectures are full on, they only go for 90 minutes but you cover quite a lot of content. The tutors (from what I hear) are all great fun and really know their stuff. The whole faculty is quite structured so you definitely know what to study as they are direct with their instructions.
You should only do this unit if you're an active reader/writer. I saw a lot of international students struggle with this unit as it is wordy and difficult, so if you are an international student, only do this subject if you're very fluent with reading/writing. In terms of difficulty, the subject can be hard at times. When writing the first essay, I had no idea how to reference and actually write a university style essay (which reflected in my result). However, you do get better with time =)
As for the exam, it's not too hard. I read over the main concepts/topics and then memorised responses ~2 days before the exam. As long as you are good at memorising facts/dates, the exam will be a breeze. I crammed 2 days prior to the exam and still managed to get 94%.
