Preparation should follow the selected subject area. A Computer and Data Science applicant should revise algorithms, programming logic, mathematics, databases, data interpretation and problem-solving. An Engineering applicant should focus on core engineering principles, mathematics and applied reasoning. A Politics and International Studies applicant should practise analytical writing, argument structure, institutions, international relations concepts and current global issues.
For Clinical Medicine and Public Health, prepare foundations rather than random trivia: epidemiology, health systems, biology, clinical reasoning and public-health interpretation. For Economics and Econometrics, revise microeconomics, macroeconomics, statistics, data interpretation and model reasoning. For Education and Psychology, review learning theory, research methods, development, assessment and applied cases.
The point is not to predict every question. The point is to become comfortable with the academic language and reasoning style of your subject. Stage 2 rewards applicants who can work under pressure, understand instructions quickly and produce clear answers without searching the internet.
