I am currently going to sit the economics topic test (covering the first 2 chapters of the syllabus) and I am wondering what people think the essay question at the end could be about. I also attend Baulkham Hills High School if that changes anything and previous questions have been about
1. PPF
2. Comparing with an Asian economy
3. (Dis)Economies of scale


Edit: The test is on 1st May so urgent help required.
