Where the marks actually go
AS Economics is assessed across two papers, AS1 Markets and Market Failure and AS2 Managing the National Economy, each worth 80 marks in 90 minutes. That works out at roughly 1 minute 8 seconds per mark on both papers, so a 6-mark diagram deserves about 7 minutes and the 20-mark essay at the end deserves close to 23. Across the papers we hold, two skills carry most of the marks between them: drawing and reading economic diagrams, and writing a balanced extended essay. Get those two right and you are covering the bulk of what decides grade boundaries on this subject.
On AS1, the chapters that generate the largest share of marks are market failures and imperfections and government intervention in markets. Elasticity of demand and supply and the basic economic problem show up in smaller, sharper bursts, usually inside Section A calculation questions. Treat elasticity as a tool you use inside bigger questions rather than a topic you revise once and set aside.
Paper by paper: structure and timing
AS 1: Markets and Market Failure (90 minutes, 80 marks)
Section A is short answer and diagrammatic work, worth around 25 marks: two short distinctions, a diagram-based calculation, an elasticity question with sub-parts, and a tax incidence diagram. Give it 28 minutes. Section B is the case study, worth around 35 marks and built from data comparison, a PPF diagram, a market failure diagram, and a 15-mark policy essay. That is close to 39 minutes, and you should read the whole case study booklet before you write a word. Section C is a single 20-mark essay chosen from two questions, worth about 23 minutes.
AS 2: Managing the National Economy (90 minutes, 80 marks)
The same three-section shape, applied to macroeconomics. Section A has six short answer questions rather than four, so keep each one brisk and do not let a definition eat more than two minutes. Section B is again a case study attached to a 15-mark policy essay, and Section C is a 20-mark essay chosen from two. Use the same rough split as AS1: about a third of the paper on Section A, well over a third on the case study, and the rest on the final essay.
Whichever paper you sit, decide your Section C question before you start Section A. Choosing under time pressure with twenty minutes left wastes minutes you do not have.
The highest-yield techniques
Diagrams are worth drilling until they are automatic. For market failure, label marginal private benefit, marginal social benefit, and the externality gap precisely, and get the welfare loss triangle pointing the right way: it sits between the private and social optimum, not wherever looks tidy. Confusing marginal private cost with marginal social cost, or drawing the triangle backwards, is one of the most common ways to lose marks even when the rest of the answer is sound. The same applies to shifts: if a diagram calls for capital equipment improving productivity, that curve should rotate around one end rather than shift outward in a straight parallel line, and both axes should not move at once unless the question genuinely asks for it.
Section B always wants you to manipulate the data in the case study, not describe it. If a table shows unemployment at 4.2% in one year and 5.8% two years later, do not just say it rose. Give the percentage point change, 1.6 percentage points, or the percentage change, about 38%, and quote the start and end figures. Markers reward calculation and comparison, not paraphrase of the numbers already printed in front of them.
For elasticity questions, state the formula first: \( PED = \dfrac{\%\Delta Qd}{\%\Delta P} \). Then show every step, the percentage change in quantity, the percentage change in price, and the division, before you give a final figure. Keep the sign. A fall of 7.6% written as "7.6%" instead of "-7.6%" or "a 7.6% fall" reads as an incomplete answer even when the arithmetic is right. This matters because CCEA applies an own-figure rule: if your method is correct but an earlier figure in the chain was wrong, you can still pick up the later marks, but only if every step is written down. A bare final answer with no working gets no benefit of the doubt if it turns out to be wrong.
The 15-mark and 20-mark essays are marked in levels, and the gap between Level 2 and Level 3 is almost always the same thing: whether you argue both sides. A one-sided answer that lists three advantages of a policy and stops is capped low, however accurate the economics inside it is. Build every essay around at least one counterargument, an unintended consequence, an implementation cost, or a time lag, and end with a judgement that actually weighs the two sides rather than repeating your opening paragraph in different words.
CCEA conventions worth knowing
Quality of written communication is assessed inside the extended writing questions themselves, not as a separate bolt-on mark. Specialist vocabulary and clear paragraphing feed directly into your Section B and Section C marks, so use the terms from the specification, negative externality, marginal social cost, contractionary fiscal policy, rather than looser, everyday phrasing.
The four assessment objectives on this course are knowledge (AO1), application (AO2), analysis (AO3) and evaluation (AO4). At AS they carry roughly 30%, 30%, 20% and 20% of the marks, which is why Section A, which mostly tests AO1 and AO2, is worth doing quickly and cleanly: it is not where the highest-value marks sit. That balance shifts toward AO3 and AO4 at A2, so the evaluative habits you build now are worth more later.
Exam day plan
Read the whole case study booklet before answering any Section B question, twice if you have time. Write down your Section C choice immediately so you are not deciding under pressure near the end. For every calculation, write the formula, then each step, then the answer with its sign and its units. For every essay, plan two supporting points and one clear counterargument before you write a sentence. Leave the last five minutes of each paper to check that every diagram has full axis labels and that every essay ends on an actual judgement, not a summary of what you already said.
