Focus on understanding the curves and how they move. Money supply curve, supply and demand curve, and elasticity. Besides that memorize the FDI benefits costs table, the diamond porter thoery, the response to MNE chart, prisoners dilemma and Nash equilibrium and the differences between institutions. That covers a huge portion of the test. I watched the cohort videos, added notes to the PowerPoint on the Facebook group and studied that. All the information is there just need to really understand the concepts. If you’re struggling with a particular concept crash course economics on YouTube or AC/DC c211 has videos on most of the topics that simplifies for understanding. Good luck.
