How to Score A* in IGCSE Economics: The Complete Paper 1 & Paper 2 Guide
MCQ elimination technique, structured answer frameworks for every command word, mark allocation strategy, the A* threshold breakdown, and a week-by-week revision plan β for Cambridge 0455.
1. What Does A* Actually Require?
Before diving into technique, let's be clear about the target. IGCSE Economics (0455) is assessed across two papers with a combined total of 120 marks (Paper 1: 30 marks + Paper 2: 90 marks). The A* threshold has varied across recent exam sessions:
| Exam session | A* threshold (out of 150*) | Approximate % |
|---|---|---|
| June 2025 | ~114β125 | 76β83% |
| November 2024 | ~122β124 | 81β83% |
| June 2024 | ~115β125 | 77β83% |
| March 2025 | ~125 | 83% |
*Raw marks are weighted: Paper 1 (30 marks) is scaled to 60, Paper 2 (90 marks) to 90 β total 150. Thresholds vary by variant.
In practical terms, A* typically requires scoring around 80% or above across both papers. That means roughly 24+/30 on Paper 1 and 72+/90 on Paper 2. There's very little room for error β which is why technique matters as much as content knowledge.
The A* mindset: You don't need to be perfect. You need to be consistent. An A* student doesn't know every topic flawlessly β they know how to maximise marks on every question they attempt. That means understanding command words, allocating time correctly, using diagrams effectively, and avoiding the common errors that drop students from A* to A. This guide is about those skills.
2. Exam Structure at a Glance
| Component | Format | Duration | Marks | Weighting |
|---|---|---|---|---|
| Paper 1 | 30 multiple choice questions | 45 minutes | 30 | 30% |
| Paper 2 | Structured questions (data response + choice questions) | 2 hours 15 minutes | 90 | 70% |
| Total | 120 | 100% | ||
Paper 2 breakdown: Question 1 is compulsory (data response, 30 marks). Questions 2β4 are chosen from a selection of four or more options, each worth 20 marks, with four parts: (a), (b), (c), (d). You answer three choice questions plus the compulsory Question 1.
Paper 2 is worth 70% of your final grade. This is where A* students are made. Paper 1 matters β losing 6+ marks on MCQ can push you below the threshold β but Paper 2 is where the most marks are available and where technique makes the biggest difference.
3. Paper 1 MCQ: How to Score 27+/30
Paper 1 gives you 30 multiple choice questions in 45 minutes β that's 90 seconds per question. Every question has four options (A, B, C, D) and one correct answer. There's no negative marking, so you should always answer every question.
The three-pass technique
Pass 1: Quick wins (15 minutes)
Go through all 30 questions. Answer every question where you're confident immediately. If you're unsure, circle the question number and move on. Don't spend more than 30 seconds on any question in this pass. You should answer 18β22 questions in this round.
Pass 2: Elimination (20 minutes)
Return to the circled questions. For each, eliminate the options you know are wrong. Even if you can't identify the correct answer, eliminating 2 options gives you a 50% chance. Use the process of elimination β cross out wrong answers physically on the paper. Most students can resolve 6β8 questions in this pass.
Pass 3: Best guess (10 minutes)
For any remaining questions, make your best guess based on elimination. Never leave a question blank β there's no penalty for wrong answers. Review your answer sheet to ensure you've marked every question correctly and haven't skipped a row.
π‘ The A* benchmark: To stay on track for A*, aim for 25β28 correct out of 30. That means you can afford 2β5 mistakes. Paper 1 questions range from straightforward recall to applied analysis β the difficulty isn't uniform. Don't panic over one hard question; focus on banking the marks you know.
4. Paper 1: The 5 Most Common MCQ Traps
Trap 1: The "always" or "never" option
Economics rarely deals in absolutes. Options containing "always," "never," or "all" are frequently wrong. Be sceptical of absolute statements β the correct answer usually acknowledges conditions, exceptions, or context.
Trap 2: Confusing shifts with movements
A change in the price of a good causes a movement along the demand curve. A change in a non-price factor (income, tastes, price of substitutes) causes a shift of the demand curve. MCQs love testing this distinction. Read carefully: is the question about a price change or a non-price factor?
Trap 3: The double-negative
"Which of the following is NOT a disadvantage of..." β these questions require you to find the positive among negatives. Underline the word NOT and evaluate each option individually. Don't rush through negative phrasing.
Trap 4: Similar-sounding options
Two options may look almost identical β "a decrease in supply" vs "a decrease in quantity supplied." These are completely different concepts. Read every word in each option. The examiners design these to catch students who skim.
Trap 5: Calculation errors
Some MCQs require simple calculations (percentage change, PED, price from a supply/demand schedule). Show your working in the margin even though it's not marked β it prevents careless errors. Double-check the unit of the answer.
5. Paper 2: Overview and Mark Allocation
Paper 2 is 2 hours and 15 minutes, worth 90 marks. It's the paper that determines your grade. Here's how the marks break down:
| Question | Type | Marks | Time target |
|---|---|---|---|
| Q1 (compulsory) | Data response β stimulus material with 6β8 parts | 30 | ~40 minutes |
| Q2 (choice) | 4-part structured question: (a) 2m, (b) 4m, (c) 6m, (d) 8m | 20 | ~25 minutes |
| Q3 (choice) | Same structure as Q2 | 20 | ~25 minutes |
| Q4 (choice) | Same structure as Q2 | 20 | ~25 minutes |
| Total Paper 2 | 90 | 135 minutes | |
The choice questions (Q2β4) follow a consistent escalating pattern: part (a) tests recall (define/identify), part (b) tests knowledge (describe/outline), part (c) tests analysis (explain/analyse), and part (d) tests evaluation (discuss/evaluate). Understanding this pattern means you know exactly what each part demands before you even read the specific question.
β οΈ The critical rule: Always choose your three questions before you start writing. Read every option. Pick questions based on part (d) β it's worth 8 marks (40% of each question). If you can't evaluate part (d), the question isn't worth choosing, even if parts (a)β(c) look easy.
6. Command Words Decoded: What the Examiner Actually Wants
Cambridge uses specific command words that tell you exactly what to do. Matching your response to the command word is the single fastest way to gain marks β and misreading it is the single fastest way to lose them.
The golden rule: If the question says "Define," don't explain. If it says "Explain," don't just define. If it says "Discuss," don't just explain one side. Every extra word you write beyond what the command word asks for is time wasted on marks you won't receive.
Want to nail every command word?
Our IGCSE Economics classes run weekly practice on structured questions β with mark-scheme feedback on every part (a) through (d). Most students see a 10β15 mark improvement within the first month.
7. Paper 2 Question 1: Data Response Technique
Question 1 is compulsory and worth 30 marks β one-third of Paper 2. It presents stimulus material (a text extract, table, or graph) and asks 6β8 sub-questions of escalating difficulty. Here's how to handle it:
Step 1: Read the questions first
Before reading the stimulus material, skim all the sub-questions. This tells you what information to look for when you read the extract. You'll read the stimulus material more efficiently because you know what's relevant.
Step 2: Use the data
This is the most common error on Question 1: students answer from general knowledge instead of using the provided material. If the question says "Using information from the extract," you must reference specific data, figures, or quotes from the stimulus. Generic answers that could apply to any economy earn limited marks.
Step 3: Match effort to marks
The sub-questions range from 1-mark identification to 6β8 mark evaluation. Spend your time proportionally. A 1-mark question needs one sentence. A 6-mark question needs a developed paragraph with cause-and-effect reasoning.
π‘ Data response shortcut: For calculation questions within Q1 (e.g. "Calculate the percentage change in GDP"), always show your working. Even if your final answer is wrong, you earn marks for correct method. Write the formula first, substitute the numbers, then calculate.
8. Paper 2 Questions 2β4: Structured Answer Frameworks
The choice questions follow a predictable 4-part structure. Here's exactly how to approach each part:
Part (a) β 2 marks: Define
Define the economic term(s) in the question. Use precise, textbook-quality language. Two sentences maximum. This is the easiest 2 marks on the paper β don't overthink it.
"Inflation is when prices go up."
"Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time."
Part (b) β 4 marks: Describe / Outline
Describe the feature, process, or characteristics the question asks about. Write 4β6 sentences. State what something is and what it involves β you don't need to explain why. Include 2β3 distinct points for full marks.
Part (c) β 6 marks: Explain / Analyse
This is where you build chains of reasoning. State what happens, explain the mechanism, and show the economic consequence. Use connective phrases: "This leads to..." / "As a result..." / "The effect of this is..." A diagram here can earn you the top marks. Write 6β10 sentences covering 2β3 developed points.
Part (d) β 8 marks: Discuss / Evaluate
The highest-value part of each question. This requires a two-sided answer with a conclusion. We cover this in detail in the next section.
Mark-per-minute rule: Part (a) should take 2 minutes. Part (b) should take 5 minutes. Part (c) should take 7β8 minutes. Part (d) should take 10β12 minutes. If you're spending 8 minutes on a 2-mark definition, your time allocation is broken.
9. Mastering Part (d) β The 8-Mark Evaluation
Part (d) is where A* students separate themselves from A students. It's worth 8 marks β 40% of each choice question β and it's the only part that tests evaluation. The mark scheme rewards two-sided analysis with a supported conclusion.
The 8-mark framework
Arguments FOR (3β4 sentences)
Present 1β2 reasons supporting the proposition in the question. Use economic reasoning: state the point, explain the mechanism, show the consequence. A diagram here strengthens your analysis.
Arguments AGAINST (3β4 sentences)
Present 1β2 reasons opposing the proposition. These should be genuine counter-arguments, not just limitations. Show how the same policy/situation could produce a different outcome under different conditions.
Conclusion (2β3 sentences)
Make a judgement. Don't sit on the fence β state which side is stronger and explain why. Use conditional language: "On balance... / It depends on... / In the short run... but in the long run..." The conclusion is where the final 1β2 marks are awarded.
"So there are advantages and disadvantages of trade protectionism."
This is a summary, not a judgement. It adds nothing the examiner doesn't already know. 0 marks for evaluation.
"On balance, protectionism may benefit a developing country in the short run by allowing infant industries to grow without foreign competition. However, in the long run, it reduces consumer choice, raises prices, and weakens the incentive for domestic firms to become efficient. The net effect depends on how quickly the protected industries can become internationally competitive."
Clear judgement + time frame distinction + conditional reasoning. Full evaluation marks.
β οΈ The most common part (d) mistake: Writing a one-sided answer. Even if you're asked "Do you think X is beneficial?" β you must present both sides before reaching a conclusion. A one-sided response is capped at 5/8 regardless of quality. Two sides + conclusion = full marks available.
10. Diagrams That Score Full Marks
Diagrams are not compulsory in IGCSE Economics, but they are the fastest way to gain marks in parts (c) and (d). A well-drawn diagram demonstrates understanding more efficiently than a paragraph of text β and examiners reward them explicitly in the mark scheme.
The 5-point diagram checklist
- Title: Every diagram needs a title that tells the examiner what market or situation you're illustrating (e.g. "The market for cigarettes after an indirect tax")
- Labelled axes: Price on the vertical axis, Quantity on the horizontal axis. Write the full words, not just P and Q
- Labelled curves: D1, D2, S1, S2 β and label any shifts clearly with arrows showing direction
- Equilibrium points: Mark original and new equilibrium (E1, E2) with corresponding price and quantity levels (P1βP2, Q1βQ2)
- Refer to it in your writing: "As shown in the diagram, the increase in tax shifts the supply curve from S1 to S2, causing the equilibrium price to rise from P1 to P2." A diagram you don't reference earns fewer marks.
Essential diagrams for IGCSE Economics
| Diagram | Used for topics | Likely question types |
|---|---|---|
| Demand & supply (shifts) | Price determination, market equilibrium, changes in demand/supply conditions | Parts (c) and (d) |
| Indirect tax (supply shift up) | Government intervention, taxation, demerit goods | Parts (c) and (d) |
| Subsidy (supply shift down) | Government intervention, merit goods, agriculture | Parts (c) and (d) |
| Price ceiling (below equilibrium) | Rent controls, maximum prices, shortages | Parts (c) and (d) |
| Price floor (above equilibrium) | Minimum wage, guaranteed prices, surplus | Parts (c) and (d) |
| Negative externality | Market failure, pollution, overproduction | Parts (c) and (d) |
| Positive externality | Market failure, education, healthcare, underconsumption | Parts (c) and (d) |
| PPC (production possibility curve) | Opportunity cost, economic growth, resource allocation | Parts (b) and (c) |
| Tariff diagram | Protectionism, international trade, import restrictions | Parts (c) and (d) |
| Demand/supply for labour | Wage determination, unemployment, minimum wage effects | Parts (c) and (d) |
Diagram quality > quantity: One well-drawn, fully labelled, and properly referenced diagram earns more marks than three rushed, unlabelled sketches. If you're short on time, draw one diagram well rather than two diagrams badly.

Every KS Academia Prep IGCSE student receives a diagram reference sheet covering all 10 essential diagrams β with step-by-step drawing guides and the exact labels examiners look for.
11. How to Write Definitions That Score Every Time
Part (a) of every choice question asks you to define a term. It's only 2 marks, but A* students treat definitions as non-negotiable β they never drop marks here. The secret is precision.
The definition formula
A strong IGCSE definition follows this pattern: Category + Key characteristic + Distinguishing feature.
"Demand" β "When people want things."
"GDP" β "How much money a country makes."
"Subsidy" β "Money from the government."
"Demand" β "The quantity of a good or service that consumers are willing and able to buy at a given price in a given time period."
"GDP" β "The total value of all goods and services produced within a country's borders in a given time period, usually one year."
"Subsidy" β "A payment made by the government to producers to reduce their costs of production and encourage increased output."
The 15 most commonly tested definitions
At minimum, memorise precise definitions for: demand, supply, equilibrium, inflation, unemployment, GDP/GNI, economic growth, opportunity cost, elasticity of demand (PED), market failure, externality, subsidy, tariff, exchange rate, and current account. These appear across nearly every exam session.
π‘ Flashcard method: Write each definition on a flashcard β term on front, precise definition on back. Test yourself daily in the final 4 weeks before the exam. The goal is automatic recall so that part (a) takes you 60 seconds, not 4 minutes.
12. Time Management Strategy
Paper 2 is 135 minutes for 90 marks. That's 1.5 minutes per mark. Here's the optimal time allocation:
0:00 β 0:05 β Read and choose (5 minutes)
Read all the choice questions (Q2 onwards). Pick your three questions based on part (d) strength, not part (a) ease. Underline command words on the questions you've chosen.
0:05 β 0:45 β Question 1: Data response (40 minutes)
Read all sub-questions first, then read the stimulus material. Answer in order. For calculation questions, show working. For data-referencing questions, quote specific figures from the extract. Aim for 26+/30.
0:45 β 1:10 β Choice Question 1 (25 minutes)
Part (a): 2 min β Part (b): 5 min β Part (c): 8 min β Part (d): 10 min. Include a diagram in part (c) or (d).
1:10 β 1:35 β Choice Question 2 (25 minutes)
Same allocation. If you're ahead of schedule, invest the extra time into part (d) evaluation depth.
1:35 β 2:00 β Choice Question 3 (25 minutes)
Same allocation. Don't rush the conclusion in part (d) β that's where the final evaluation marks sit.
2:00 β 2:15 β Review (15 minutes)
Re-read your part (d) conclusions β is each one a genuine judgement or just a summary? Check your diagrams are titled and fully labelled. Scan for any blank answers. Add economic terminology wherever you used vague language.
β οΈ The #1 timing error: Spending too long on Question 1. It's worth 30 marks but students often treat it like it's worth 50. If you exceed 45 minutes on Q1, you're stealing time from three questions worth 60 marks combined. Set a hard 40-minute limit and move on.
13. 10 Common Mistakes That Cost A*
These are the errors we see most frequently in our IGCSE Economics students β each one individually costs 2β5 marks. Eliminating just three or four of these is often the difference between A and A*.
- Vague definitions. "Inflation is when things get expensive" loses the mark. Use precise economic language with key qualifiers: "sustained," "general price level," "over a period of time."
- Not using the data in Q1. The data response requires you to reference specific numbers, trends, and quotes from the extract. General knowledge answers are capped at low marks even if technically correct.
- One-sided part (d) answers. Presenting only advantages or only disadvantages caps you at 5/8 regardless of quality. Always present both sides, then conclude.
- No conclusion in part (d). "In conclusion, there are pros and cons" is not a conclusion. A conclusion states which side is stronger and why, using conditional reasoning ("It depends on... / In the short run... / For a developing country...").
- Diagrams without labels or references. An unlabelled diagram earns minimal credit. A labelled diagram that isn't referenced in your writing earns partial credit. A labelled, titled diagram that's explicitly discussed in your answer earns full marks.
- Choosing questions based on part (a). Part (a) is only 2 marks. Part (d) is 8 marks. Pick the question where you can write the strongest evaluation, not the easiest definition.
- Writing too much for low-mark questions. A 2-mark definition should be 1β2 sentences. If you're writing a paragraph for part (a), you're wasting time that should go to part (d).
- Confusing economic concepts. GDP vs GNI, demand vs quantity demanded, movement vs shift, positive externality vs merit good. These distinctions appear in MCQs and structured questions alike.
- No chains of reasoning in part (c). "Inflation causes problems" earns 1 mark. "Inflation reduces the purchasing power of consumers, meaning they can afford fewer goods and services, leading to a fall in living standards" earns 3 marks. Build the chain: cause β mechanism β consequence.
- Poor time allocation. Running out of time on the last question is the most preventable mark loss. Practice under timed conditions and stick to the schedule in section 12 above.
Eliminate these mistakes in 4 weeks
Our IGCSE Economics exam technique programme targets these exact errors β with weekly timed practice, mark-scheme feedback, and personalised error tracking. Most students close the gap to A* within one month.
14. The 8-Week IGCSE Economics Revision Plan
This plan assumes you've covered the syllabus content and are now focused on exam preparation. Adjust the timeline based on your exam date β the key principle is moving from content consolidation to full timed practice.
Weeks 1β2: Content audit & gap-filling
Go through the syllabus checklist topic by topic. For each topic, ask: "Can I define the key terms? Can I draw the relevant diagram? Can I explain the economic mechanism?" Topics where you answer "no" to any of these are your priority. Consolidate your notes β don't create new ones from scratch. Use past paper questions to identify which topics you're weakest in.
Weeks 3β4: Definition bank & diagram drill
Memorise your 15β20 key definitions using flashcards. Practice drawing all 10 essential diagrams from memory until each one takes under 60 seconds. Aim for a complete set of labelled, titled diagrams you can reproduce under exam conditions. Start doing Paper 1 MCQ sets (30 questions in 45 minutes) β aim for 25+/30 consistently.
Weeks 5β6: Structured question practice
Do 2β3 full choice questions per day (parts aβd, 20 marks each). Mark your own work against the published mark scheme. Focus specifically on part (d) evaluation: are you presenting both sides? Is your conclusion a genuine judgement? Track your marks β you should see improvement from week to week. Start doing full Question 1 data responses under timed conditions (40 minutes).
Weeks 7β8: Full timed papers & refinement
Do at least 3 full Paper 2s under strict exam conditions (2 hours 15 minutes, no notes, no breaks). Mark against the mark scheme. Identify any remaining weak areas and drill those specific topics. In the final week, review your definition flashcards daily, do one Paper 1 MCQ set every other day, and re-read the mark scheme for part (d) β understanding what examiners reward is the final edge.
π‘ The KS Academia Prep approach: In our IGCSE Economics programme, students complete 6+ full timed papers in the final month before the exam, each marked against the Cambridge mark scheme with written feedback. By exam day, the format feels familiar, the timing feels natural, and the technique is automatic. The exam becomes a performance, not a surprise.
15. Frequently Asked Questions
The A* threshold varies by exam session and variant, but typically falls between 76% and 83% of the total weighted mark (out of 150). In recent sessions, this has been approximately 114β126 marks. Aim for 80%+ to comfortably clear the threshold regardless of the session difficulty.
Paper 1 is worth 30% of your final grade. It's 30 multiple choice questions in 45 minutes. Raw marks (out of 30) are scaled to 60 for the purposes of calculating your overall grade. Every MCQ error costs you 2 weighted marks.
Paper 2 is 2 hours and 15 minutes (135 minutes) for 90 marks. You answer one compulsory data response question (30 marks) and three choice questions from a wider selection (20 marks each). Paper 2 is worth 70% of your final grade.
You answer 4 questions total: Question 1 (compulsory data response, 30 marks) plus 3 choice questions from the remaining options (20 marks each). Read all choice questions before deciding which three to attempt.
Diagrams are not strictly compulsory, but they are strongly rewarded by the mark scheme β especially in parts (c) and (d). A well-drawn, labelled, and referenced diagram can earn you 1β2 additional marks per question. For A* students, diagrams are effectively essential.
"Explain" requires you to give reasons and build a chain of reasoning β state what happens and why, using cause-and-effect logic. "Discuss" requires you to present arguments for and against a proposition, then reach a reasoned conclusion. Discuss always demands two sides; explain does not.
Practice with past papers under timed conditions (45 minutes for 30 questions). After each set, review every wrong answer and understand why the correct option is right. Focus on the topics that catch you out most β typically elasticity, market failure, and macroeconomic indicators. Aim for 25+/30 consistently before exam day.
No. There is no negative marking in Cambridge IGCSE Economics. You should always answer every question, even if you're unsure. A guess gives you a 25% chance; a blank gives you 0%. Use the elimination technique to improve your odds before guessing.
