The Importance of Mark Schemes for Economics Exams (IGCSE, A Levels, IB Diploma Program)

Victor Tan
 

Hello, sepupus?

Do you like doing well on exams? Does that er, maximize your utility?

Well, listen up.

Mark schemes are crucial for getting those sweet, sweet, beautiful marks in your Economics (or pretty much any other) exams, whether IGCSE, A Levels, IB, or pretty much anything else — If you’re wondering why I specifically said good at economics exams, just ask yourself: Does being good at economics exams immediately or directly mean that you are good at thinking as an economist? That’s an interesting question, but what’s for sure is this:

If you cannot do well in economics exams, it is very unlikely that somehow or another you are secretly a truly incredible economist. And with that in mind, exams as tests are crucial and it is entirely possible to get higher marks if we understand how those marks are given out.

Here is where mark schemes come in, not just for examiners, but for students who want to excel.

Here’s why!


🎯 1. They Reveal the Target

Mark schemes tell you exactly what the examiner is looking for. Economics is not just about writing something that’s “kind of correct.” It’s about hitting specific keywords, concepts, and logical chains that the examiner has been told to reward.

For example, if the question is:

Explain two reasons why a firm may benefit from economies of scale.

The mark scheme might expect:

  • One valid type of economy of scale (e.g. purchasing, managerial)
  • A clear explanation of how it reduces average cost

Vague answers like “the firm grows” don’t get marks—even if they’re sort of true; each exam has specific criteria and conditions under which marks can be procured. And if you don’t try to understand them or actually work with the real marking documents in the first place, there’s a very high chance that you will just end up concluding that exams are unfair. The system was rigged against you and you didn’t have a chance when actually it was your own fault for not seeking out this important resource.

Also, understanding the syllabus and assessment objectives is one thing and it’s nice to have and it’s good to have that understanding, but you also need mark schemes; mark schemes offer you concrete and hard reasons as to why a particular answer is correct and will give you a valuable picture of what is correct for the exam that you happen to be taking.


🧠 2. They Train You to Think Like an Examiner

By reading mark schemes, you begin to internalize the examiner’s mindset. You learn to:

  • Structure your responses in logical steps (e.g. define → apply → analyze)
  • Avoid waffle
  • Anticipate the level of depth required for questions
  • Sympathize with examiners and imagine what it would be like if you were actually forced to evaluate other people.

This is especially useful in data-response questions or evaluation-based questions, where many students lose marks by either over-explaining or under-developing points.

A little bit more on this. You should try as a student or a parent to understand how an examiner thinks.

It is very worthwhile to do this.

Consider that an examiner wants to reward you for sharing your knowledge and ask yourself what the examiner needs to know in order to give you credit for your answers – They are not here to harm you or to trip you up immediately. Rather, they are performing a very important role in deciding who should be given credit and how they should determine who are the wheat and who are the chaff within the exam cohort. To separate out clearly who are the best – the ones who are good and the ones who unfortunately do not make the cut.

This logic is not exclusive to examiners. If you were to think about it long enough, you might see that there is a societal need for this kind of differentiating behavior, and you might in turn see that at some point, you might have to make the same decisions as well. So, be an examiner for the day, and think about what you would be looking for if you were in their position. It will be valuable for you.


📝 3. They Teach You the Language of Economics

Mark schemes highlight the specific terminology that Cambridge values. Using the correct economic language (e.g. “opportunity cost,” “price elasticity of demand,” “allocation of resources”) can make the difference between a 5 and an 8.

Having examples in front of you will make it very much easier for you to get used to using that language across all future situations, and make it so you don’t just start waffling out things that people won’t understand. It’s not about infinite creativity across a span of things that are ultimately not relevant. Rather, it is about being able to use the language in the common world that you are studying and being able to make use of it in the most effective, well-reasoned ways. Language is not merely about sounding pretty. It is also about being effective. And the mark schemes tell you very clearly what is effective, even if you may have to interpret them and may need good examples (hint: Join Premium!).


🧩 4. They Help You Understand Assessment Objectives

Each question in Economics (IGCSE and A Levels) is mapped to certain Assessment Objectives (AOs) like:

  • AO1: Knowledge and understanding
  • AO2: Application and analysis
  • AO3: Evaluation

Mark schemes show how each of these is rewarded. So if a question is AO3-heavy, you must evaluate—e.g. by weighing alternatives, recognizing limitations, or giving reasoned judgments. Understanding how the assessment objectives work in conjunction with what the mark schemes offer is highly helpful, especially when you have a good teacher or tutor on hand who is able to help you identify the deeper patterns that lie within.

The same is true for the International Baccalaureate as well, which in turn has its own dynamics – for example, knowledge and understanding of economic theories, application analysis, synthesis, and evaluation in Papers 1 and 2, and accuracy of calculations in Paper 3; almost every IB student also probably has nightmares about the rubrics for the extended essay and also for the commentaries that they have to produce as part of a portfolio throughout their entire career.

The IB has its own ways of assessing what is a good IB economics essay, and we’ll talk more about that soon even as I begin to provide and articulate examples that will come out in this website.

But the basic point is this: it doesn’t matter what curriculum it is – you need to find out how you will be marked in order to understand the broader goals of what you’re being taught to do, and you need not just to have that broad overview of the picture or the direction in which things are going but also need a very clear understanding of how things are evaluated on the more granular levels, whatever exam you are taking.


    📊 5. They Are a Study Tool in Themselves

    Mark schemes let you reverse-engineer good answers. When practicing past papers, you can:

    • Compare your answer to the mark scheme
    • Spot missing points or overcomplicated explanations
    • Learn what earns marks and what doesn’t

    It’s one of the most efficient ways to improve.

    The reason for this is that you want to make sure that you are hitting the right notes, and the mark scheme is basically a source of truth for you. The more you compare your answers to mark schemes and the more you become able to produce answers that hit the correct note, the higher the marks you will get in your exams as compared to what you would have gotten if you had not seen the mark schemes in the first place.


    ✅ Summary

    Mark schemes aren’t just tools for checking your score—they’re guides for mastering the exam. If past papers are the questions, mark schemes are the answer key to success. Learn their logic, adopt their style, and you’ll write answers that the examiner wants to reward.

    They are your keys to the kingdom of economics heaven. Or if you are not religious, then to the mansion. The luxury car or to the dream holiday destination where you can meditate beyond the confines and constraints of banal human life into the higher reaches of a more beautiful universe.

    Take your mark schemes friends and use them as a part of your strategy. Don’t listen to me tell you this over and over again. Reading what I say and hearing me tell you things is only going to get you so far. You can have all the premium resources that you want, but you must use them. You must be proactive, and you must take your learning into your own hands. It is an honor to be a part of your journey, but you are far from done. Go further and farther, and if you want to thank me, do it after you succeed.

    I look forward to hearing your stories!

    Understanding Your Command Words in IGCSE Economics

    Victor Tan
     

    Today’s blog post is about what we call command words in the IGCSE.

    Command words are extremely important because these are the words that you’re going to see in every IGCSE question.

    Each one has a specific meaning as identified by Cambridge, and it is crucial to understand all of them in order to understand how you should respond.

    …How wonderful that your beloved sepupu has compiled not only a list of your command words but also will be demonstrating how to make use of them!

    Without further ado, here are your command words as taken from the IGCSE Cambridge Economics syllabus – these were the same across the 2023 -2025, 2026, and 2027-2029 syllabi – behold!

    Now that you know what the command words are, let’s look at some tangible examples of situations where they would be used and how they would be used.

    Ready?

    Let’s go!


    1. Analyse

    “Examine in detail to show meaning, identify elements and the relationship between them.”

    Example Question:

    Analyse how an increase in interest rates might affect consumer spending and borrowing.

    What to Do:

    • Identify the elements: interest rates, consumer spending, borrowing.
    • Show the relationships: Higher interest → costlier loans → less borrowing → lower spending.
    • Include linking phrases like: “This leads to…”, “As a result…”, “Consequently…”.

    Use:

    “As interest rates increase, the cost of borrowing rises. This discourages consumers from taking loans for major purchases such as cars and homes. At the same time, saving becomes more attractive, reducing overall consumer expenditure.”


    2. Calculate

    “Work out from given facts, figures or information.”

    Example Question:

    Calculate the price elasticity of demand using the following data: Price rises from $10 to $12, quantity demanded falls from 100 to 80.


    3. Define

    “Give precise meaning.”

    Example Question:

    Define opportunity cost.

    Answer:

    “Opportunity cost is the next best alternative foregone when a decision is made to use scarce resources for one purpose over another.”

    ✳️ No examples needed unless asked for.


    4. Describe

    “State the points of a topic / give characteristics and main features.”

    Example Question:

    Describe the characteristics of a mixed economy.

    Answer:

    “A mixed economy is one where both the private sector and the government are involved in resource allocation. It combines features of a market economy, such as private ownership and profit motive, with government intervention in areas like education and healthcare.”

    🔹 This is factual, descriptive — not evaluative. You are not expected to talk about whether a mixed economy is good or bad. You are only meant to retrieve your understanding and memory of what you are being asked about.


    5. Discuss

    “Write about issue(s) or topic(s) in depth in a structured way.”

    Example Question:

    Discuss whether a government should subsidise the production of electric vehicles.

    Answer Structure:

    • Introduction of the issue
    • Arguments for subsidies: reduce pollution, encourage innovation
    • Arguments against: opportunity cost, risk of inefficiency
    • Conclusion: balanced, thoughtful judgment

    Answer Snippet:

    “Subsidising electric vehicle production can encourage environmentally friendly transport and reduce emissions. However, it may be costly for governments and could distort the market. Whether it is justified depends on the long-term environmental and economic benefits.”


    6. Explain

    “Set out purposes or reasons / make the relationships between things clear.”

    Example Question:

    Explain why inflation can hurt savers.

    Answer:

    “Inflation reduces the purchasing power of money. If savers keep their money in accounts with low interest rates, the real value of their savings falls, meaning they can buy less with the same amount of money over time.”

    ✳️ Look for cause-effect chains. To get good at this, start thinking about how everything you are learning relates together and ask yourself how different factors can affect one another. Don’t just commit things to memory but actually think about the common sense implications of how certain factors can cause other things to happen. Get used to doing that repeatedly.


    7. Give

    “Produce an answer from a given source or recall/memory.”

    Example Question:

    Give one example of a merit good.

    Answer:

    “Education.”

    ✳️ Usually just a one-word or short-phrase recall question.


    8. Identify

    “Name/select/recognise.”

    Example Question:

    Identify two causes of unemployment.

    Answer:

    “Cyclical unemployment, structural unemployment.”

    ✳️ Similar to “Give”, but may come with options or lists.


    9. State

    “Express in clear terms.”

    Example Question:

    State one function of a central bank.

    Answer:

    “To control the money supply.”

    ✳️ Be concise, clear, and exact.

    Hope this was helpful to you. Thank you for reading, and look forward to seeing you in the next ones!

    IGCSE Economics – Assessment Objectives

    Victor Tan
     

    As a student, you’ve probably understood for a long time now that you are assessed on pretty much everything that you do, whether it’s homework, exams, class participation, or anything else that you can imagine.

    Well, IGCSE Economics (Cambridge Subject Code 0455) is no different.

    The subject too has its own set of assessment objectives – things that define how you will be assessed as an economics student, whether as a good one or a not-so-good one.

    So let’s be a little more clear about this.

    🧠 What Are Assessment Objectives?

    Assessment objectives (AOs) are the specific skills, abilities, or understandings that a student is expected to demonstrate in order to be evaluated meaningfully. They form the foundation of what is being assessed.

    They answer the question:

    What exactly are we trying to measure?


    🔍 How Do They Relate to the Word “Assess”?

    Remember the Latin assidēre — “to sit beside [a judge]”? The role of the assessor was not merely to observe but to make a judgment — based on criteria.

    Assessment objectives are the modern expression of those criteria.

    They:

    • Define what kinds of knowledge or skill are being valued.
    • Provide a basis for judgment (standardization).
    • Make the act of assessing transparent and justifiable.

    These are not suggestions — they are what will determine your score. Your writing is assessed against these.

    ⚙️ Why Are Assessment Objectives Important?

    1. Clarity: They tell you what matters. (No more guessing what the examiner wants.)
    2. Consistency: Markers can evaluate different students against a shared standard.
    3. Fairness: Students are judged by performance against stated criteria, not impressionistic bias.
    4. Design Alignment: Exams, rubrics, and mark schemes are all structured to reflect the AOs.

    🧩 What It Means in Practice

    When a teacher marks a paper, they’re not just saying “This is good” or “This is weak.”

    They’re implicitly (or explicitly) saying:

    • Did this student demonstrate AO1?
    • How well did they meet AO2?

    In other words:

    We assess in reference to the assessment objectives.

    We measure in reference to assessment objectives – we quantify, count, judge.

    If a student demonstrates what we are looking for, we reward that – if they don’t, we do not.

    Does it seem arbitrary? Are your marks too low? Then maybe understand the assessment objectives more closely and the marking schemes that operationalize them in the exam context to determine how every single point is allocated and accounted for.


    🧠 How Do Assessment Objectives Matter?

    The phrase “assessment objectives” is a kind of contract: it declares what you will be judged on, in advance. It aligns the ancient role of the assessor — sitting beside the work — with the modern idea of accountability, standardization, and pedagogical clarity.

    It transforms “assessment” from something vague and fearful into something logical and methodical — something you can engineer.

    Now let’s do a bit of a deep dive into all of the assessment objectives and why they matter in this context.

    1. AO1 – Knowledge and Understanding

    According to Cambridge, to demonstrate knowledge and understanding, you need to know about economic definitions, formulas, and ideas. But that’s not all. You need to be able to prove your understanding and show your ability to use the language of economics.

    When I say use the language of economics, I don’t mean that you just repeat the definition like a parrot.

    I mean that you are actually able to make use of the definitions in order to understand the real world. To understand the situations that you are presented. To be able to look at things that are happening and then make assessments based on the theory that you’re going to be learning.

    If it were just about memory, then you could just memorize an economics textbook. But that’s not all you need to do for knowledge and understanding go beyond that – it is about being able to fluidly use the concepts that you’ve learned. Understand when to use them and understand intuitively how they apply when confronted with novel situations. But this then brings us to…

    2. AO2 – Analysis

    Knowledge and understanding is about understanding the facts and comprehending them. Analysis is about using your knowledge and understanding.

    Being able to analyze means being able to look at what you see and understand it by understanding the patterns that are present, and to be able to comment effectively and intelligently on what you’re seeing.

    For example, suppose that there is a drought in an onion-producing country (India, let’s say – the country produces the majority of Malaysia’s onions).

    Here are some questions that you might ask and some that you might be expected to be able to respond to.

    • How does that affect the demand for onions? Does it affect it or does it not affect it?
    • How does it affect the supply?
    • How does it affect the price? Will it definitely affect the price? What might influence that?
    • Can you illustrate that situation with graphs?
    • Can you predict the effect on the price of onions based on the theory that you’ve learned?
    • Based on onion data, before and after the drought, can you make any statements that are supported by the data and that you have good reason to believe?
    • Can you reason about what happened if the price of onions has fallen if there was a massive harvest season?
    • Can you look at a diagram that somebody has drawn or written and then understand what is being said?
    • Can you look at novel or new situations and then analyze them as and when you will?
    • Can you look at what is happening out there in the world and then break down larger problems into smaller ones?
    • How do the dots connect and why?
    • Can you clearly and logically justify every statement you make about the world based on what you’ve learned, and formulate intelligent arguments that can guide people’s decisions?

    All of these are related to being able to analyze situations – to look beneath what you see on the surface to discover the deeper truths.

    That’s the skill that you will learn on this course, and it may be more practical than you even know or think about at the moment.

    3. AO3 – Evaluation

    Analysis was about understanding things and developing a single interpretation, but you can think of evaluation as the skill to choose between different interpretations and to consider limitations and alternatives. It means weighing alternatives, judging them against one another, and understanding and being able to choose between different analyses of situations.

    Why is this important? Well, the late Charlie Munger once said, “To the man with a hammer, everything is a nail.”

    In this context, you can think of the hammer as the economic theory. The problem is, oftentimes we are the ones holding the hammers, especially when we don’t have a strong understanding and can’t accurately or clearly think about what is happening in this world, often finding ourselves in the wrong territory infinitely more likely or often than in territory where we are correct, caught in the parroting of definitions, the usage of understanding in order to find constellations of real patterns in the stars and in the markets but somehow being unable to choose the correct ones.

    Consider some of the following points:

    • Economics is complex. The choices that people make depend on many different factors, and there are many different ways of understanding how or why something happens. The question is, what are the correct ways of understanding things, and can you show that you recognize the fact that there are many different ways of understanding the world?
    • Not every analysis of data is necessarily correct. There can be gaps, data insufficiencies, problems with the method of analysis, or the way that a claim was argued that ultimately makes it impossible to make a reasonable or logical conclusion.
    • At the end of the day, not all conclusions, assessments, or opinions are equal. There are some that are better than others.
    • Are you able to choose the best ones? Not only the ones that you hear or parrot from other people, but rather the ones in your own mind, even as they compete for your attention for the right to shape your understanding of the world?

    And well, that’s about it. It’s pretty interesting to think about what makes a good economics student.

    But knowledge, analysis, and evaluation are a good place to start.

    I would point out, though, that these are not siloed things.

    One cannot evaluate without being able to do an analysis, and one cannot do an analysis without having knowledge in the first place – but at the same time, having more knowledge increases the likelihood that a person can conduct a good and useful analysis, while experience of analysis in turn helps make a person familiar with patterns of thinking that are not just their own but also potentially other people’s.

    The question of how to develop these skills is one that is highly individual but that comes from curiosity and a wish to develop the learning necessary to satisfy it as well as the hunger to continue being curious for a lifetime – but to begin doing that, you must first ask the question.

    From there, whether you like it or not, your mastery can be assessed, quantified, put into tangible numbers through the assessment objectives.

    It can seem a little harsh, but it is a fact – there is a difference between good and bad, and if you’re here, sepupus, you know what to aim for. ✨

    Here is to your economics journey and to many more of those questions – Hope you enjoyed learning about the Assessment Objectives (AO), and see you in the next ones ahead!
