What Cambridge International Economics 9708 covers
The first six units develop content shared by AS and A Level. The next five add A Level depth. The official syllabus lists the areas but does not assign a percentage to each one.
AS uses Papers 1 and 2; A Level uses Papers 1–4
AS Level: Paper 1 is a 60-minute multiple-choice paper with 30 questions and accounts for 33% of the AS Level result. Paper 2 is a 120-minute data-response and essay paper and accounts for 67%.
A Level: Papers 1 and 3 each account for 17%; Papers 2 and 4 each account for 33%. Students may complete Papers 1 and 2 first and Papers 3 and 4 later, or take all four in the same examination series.

Calculators may be used on all four papers. Formulae are not supplied in the question papers, so students must know the required formulas. Check the official 2026–2028 syllabus for current requirements. These details are stated as of 2026-10-09.
Follow a demand shift from equations to a market diagram
Read each question as it appears on the exam paper, choose your answer, then tap it to see the feedback.
A town market for reusable bottles experiences stronger low-waste preferences. At every price, buyers now demand 20 thousand more bottles. Supply is unchanged.
Demand is initially P = 100 − Q and supply is P = Q, giving an equilibrium of Q = 50 and P = 50. (a) Write the new demand equation. (b) Calculate the new equilibrium price and quantity. (c) Explain the change using a demand-and-supply diagram.
Show your working and label the diagram clearly.
A. Change demand to P = 120 − Q, keep supply at P = Q, and solve for Q = 60 and P = 60.
✅ Correct! 😊 This converts the 20-thousand increase at every price into a rightward demand shift. Equating the new demand curve with unchanged supply gives the correct new intersection.
B. Move along the original demand curve until Q = 70, leaving P = 50.
❌ Not quite 😭 This treats a preference change as movement caused by price. It also ignores that equilibrium requires quantity demanded to equal quantity supplied.

C. Change supply to P = Q + 20 and solve for Q = 40 and P = 60.
❌ Not quite 😭 This shifts the wrong curve. The information changes buyers’ preferences, while supply is explicitly fixed.

D. Change demand to P = 80 − Q and solve for Q = 40 and P = 40.
❌ Not quite 😭 This represents weaker rather than stronger demand. Adding 20 thousand to quantity demanded raises the demand intercept from 100 to 120.

Full explanation
- Step 1Stronger low-waste preferences are a non-price determinant, so they shift demand rather than cause movement along D1.
- Step 2An extra 20 thousand bottles demanded at each price changes P = 100 − Q to P = 120 − Q.
- Step 3Set new demand equal to unchanged supply: 120 − Q = Q, giving Q = 60 and P = 60.
- Step 4Draw D2 to the right of D1 and label E1 (50, 50) and E2 (60, 60).
An economy can produce either medical equipment or consumer goods with its existing resources.
Moving along its production possibility curve from one combination to another increases medical-equipment output by 15 units and reduces consumer-goods output by 45 units. What is the opportunity cost of one additional unit of medical equipment?
Choose one answer.
A. 3 units of consumer goods
✅ Correct! 😊 Correct. Divide the 45 units of consumer goods forgone by the 15 additional units of medical equipment gained.
B. ⅓ unit of consumer goods
❌ Not quite 😭 This reverses the ratio and calculates medical equipment gained per consumer good lost. The question asks for consumer goods forgone per extra unit of equipment.

C. 30 units of consumer goods
❌ Not quite 😭 This subtracts the two changes instead of forming an opportunity-cost ratio. Subtraction does not express the cost of each additional unit.

D. 60 units of consumer goods
❌ Not quite 😭 This adds the output changes, although they measure different products and opposite directions. Opportunity cost uses the forgone amount divided by the amount gained.

Full explanation
- Step 1Identify the gained output: 15 additional units of medical equipment.
- Step 2Identify the next-best output forgone: 45 units of consumer goods.
- Step 3Calculate 45 ÷ 15 = 3 units of consumer goods per additional unit of medical equipment.

What is the official Cambridge International AS & A Level Economics (9708) exam structure?
AS Level: AS Level Multiple Choice (60 min, 30 questions, 33%); AS Level Data Response And Essays (120 min, 67%) | A Level: AS Level Multiple Choice (60 min, 30 questions, 17%); AS Level Data Response And Essays (120 min, 33%); A Level Multiple Choice (75 min, 30 questions, 17%); A Level Data Response And Essays (120 min, 33%). These figures come from the current Cambridge International specification; where Cambridge International does not publish a per-unit weighting, this guide does not invent one.
Build a repeatable route from evidence to an economic judgment
Pass 1 — identify the command and setting. Decide whether the task asks you to define, calculate, explain, analyze, discuss, or evaluate. Name the market, economy, group, and time period before choosing a model.
Pass 2 — choose the representation. Use a formula for a measured relationship, a diagram for an equilibrium or distribution, a table for comparisons, and a causal chain for policy or market effects. Make axes, curves, units, and directions visible.
Pass 3 — reproduce complete examples. Work from question to calculation and answer without hiding substitutions, percentage bases, signs, currency units, or assumptions. Compare your work with the four-column check.
Pass 4 — add evaluation that changes the conclusion. Test the result against elasticity, size, timing, expectations, spare capacity, stakeholder effects, or the stated exchange-rate system. Finish by naming the condition that matters most.
Mix all four papers. Practice multiple-choice selection, data-response interpretation, and essays that develop analysis before evaluation. Since formulas are not supplied, recall them and explain what each variable measures.
Cambridge International publishes no per-unit percentage for Cambridge International A Level Economics; Paper 1 accounts for 33% of the AS Level total and 17% of the A Level total. Use weak decisions to guide extra repair time while continuing to revisit all eleven areas.
