The meat of this subject is in the first ~6-7 weeks, where you will be introduced to three distinct models of trade: the Ricardian model (which anybody who has microeconomics will already be familiar with), the Specific Factors model, and the Heckscher-Olin model. Understanding the ins and outs of these models is central towards succeeding in this unit. The rest of the unit is mostly extensions of these models (e.g. what happens if you relax the assumption that labour is immobile across countries, welfare analysis, the effects of tariffs and quotas in these models, etc) and tacked on during the final 2 weeks is a discussion of exchange rates and capital flows.
Lectures: As I said above, the lectures weren't recorded and I didn't attend any of them. The slides were quite detailed and the lecturer made great efforts to link the material to the content covered by the powerpoint. The lecturer was quite good (I had him as my tutor as well).
Tutorials: Discussion of the assigned questions for the week. Tutes were very valuable; I would highly recommend you attend them.
Homework tasks: Pretty straightforward, very similar to the tutorial questions. They gave you a few questions and marked one of them at random. You should definitely try to get 100% on both of these because it's a free 10% up for grabs.
Mid-sem: Multiple choice, about 30 questions. Not too bad in terms of difficulty, just make sure you have a really good grasp of everything on the slides. The lecturer directly referred to content from the lectures for nearly every single question.
Exam: This was really, really difficult this year. I kind of expected it to be similar to tutorial/homework questions, but it was much more detailed than that. Luckily, it seems that the exam was scaled up a lot because I really didn't think I got more than 50% on it but somehow ended up with a HD. My advice on the exam would be this: don't skip over some topics just because they haven't been assessed in other tasks. You need to have a strong
