CB2 Business Economics Paper Guide for IAI Actuarial

How to prepare Business Economics

1. Start with the big picture. Read the chapter list once and sort it into three groups: firm and market topics (microeconomics), economy-wide topics (macroeconomics), and the short schools-of-thought topic. Note that micro and macro together carry most of the weighting, so they deserve most of your time.
2. Build the micro core first. Learn demand, supply, elasticity, costs, revenue and the profit-maximising rule. Know that a profit-maximising firm chooses the output where marginal revenue equals marginal cost, and be ready to explain the conditions and the second-order idea behind it. Then compare perfect competition, monopoly and imperfect competition.
3. Practise diagrams until they are automatic. Draw demand and supply shifts, cost curves, and the equilibrium under each market structure. Label axes and curves every time. Then write two or three sentences explaining what the diagram shows. Examiners reward the explanation as much as the picture.
4. Move to macroeconomics with a cause-and-effect habit. For each topic, such as inflation, unemployment, exchange rates or interest rates, write down causes, effects on businesses, and policy responses. Link them across chapters: for example, how interest rate changes affect borrowing, investment, the exchange rate and demand.
5. Cover the schools of thought and recent macroeconomic history briefly but accurately. Learn each school's main belief and its policy view in your own words. Use recent history as examples of theory in action rather than as a list of dates.
6. Tie everything to business and financial services. Practise asking how each idea affects a firm's pricing, costs, investment or risk. This matters for chapters on pricing in financial services, government intervention, globalisation and the financial system.
7. Practise past questions in two stages. First do MCQs in short timed blocks to test recall and accuracy. Then answer written questions fully, and compare your answers with the examiner's report to see what earned marks and what was missing.
8. In the final weeks, revise from your own one-page summaries per chapter. Sit at least two full timed papers of 3 hours 15 minutes. Review every lost mark and note whether it came from a knowledge gap, a weak explanation or poor time use.

Time management in the exam

• →Check how many MCQs the paper has and what they carry. Each is 2 marks, so give them a fixed block of time and do not let one hard question eat several minutes. Mark it, move on and return if time allows.
• →Split the time by marks. With 100 marks in 3 hours 15 minutes, you have a little under two minutes per mark. Use this as a guide so a 10-mark question does not get 30 minutes.
• →Spend the first minute or two of each written question planning. Jot down the key terms, the diagram you will draw and the order of your points. A planned answer is shorter and scores more.
• →Keep diagrams quick and neat. Draw them with a pencil and ruler if allowed, label them once and refer to them in your text. Do not redraw unless something is clearly wrong.
• →Answer every question, even partly. Written questions usually award marks for each valid point, so a short answer with the right terms beats a blank page.
• →Leave time at the end to read through. Check that you answered each part of each question, that diagrams are labelled and that your points are applied to the situation in the question.
