Exam Format

Please note the exam format proposed here is subject to examinersa (internal and external) approval. You will be notified if there are changes resulting from the examinersa moderation.

The proposed exam is in two parts. Section A contains short answer questions and Section B is essay questions.

Section A consists of 6 questions and students are required to answer ALL of them. Section B has 4 questions and students are required to answer only ONE of them. Section A and Section B contributes towards 60% and 40% of the written exam mark, respectively.

Each Section of the exam has both Microeconomics and Macroeconomics questions and the split between the two is roughly equal. This means that the marks are split in half between Microeconomics and Macroeconomics.
