How to Pass JAMB Economics in 2027

Economics is a subject where understanding beats memorising, but understanding takes a particular form. You are not asked to give opinions on the economy. You are asked to use precise terms the way economists use them, and to apply a few simple rules to simple numbers. Candidates who write well in class often lose marks on UTME because the options are built to punish loose language.

This guide is for the 2027 cycle. It explains how to turn Economics into a set of ideas plus a set of sums.

The format

Economics is a chosen subject, and it carries 40 questions in the UTME CBT. Because the test is computer-based and objective, you win by being accurate and quick: every definition you know cold and every sum you can do in under a minute buys time for harder items. The exact time limit and format are on jamb.gov.ng. If you are choosing subjects for a course such as Accounting, Banking and Finance or Business Administration, check the subject combination for Economics and your university's requirements.

Think in four blocks

Instead of ten unrelated chapters, group the topics into four blocks:

When you open a new chapter, ask which block it belongs to. That tells you what kind of question to expect.

Demand and supply: master the shifts

The idea that costs candidates most marks is the difference between a movement along a curve and a shift of the curve.

• A change in the price of the good itself moves you along the demand curve.
• A change in income, tastes, the price of other goods, or the number of buyers shifts the whole curve.

Learn the five usual causes of demand shifts and the five usual causes of supply shifts (cost of inputs, technology, taxes and subsidies, number of sellers, expectations). Then when a question says, "Fuel subsidy is removed and transport costs rise," ask: is this a supply shift or a demand shift? For transport firms, input costs rose, so supply moves left.

Substitutes and complements matter. If the price of garri rises, demand for rice may rise, because they are substitutes. If the price of cars rises, demand for petrol may fall, because they are complements.

Elasticity: the sum you must be able to do

Price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price. Here is an original example.

The price of a product rises from ₦100 to ₦120, and the quantity demanded falls from 50 units to 40 units. What is the price elasticity of demand?

• Change in quantity: 10, which is 20 per cent of 50.
• Change in price: 20, which is 20 per cent of 100.
• Elasticity = 20 / 20 = 1. Demand is unit elastic.

Strictly, the answer is negative, because price and quantity demanded move in opposite directions. Options normally quote the size of the figure, so drop the minus sign unless the question asks about it. Remember the three bands: greater than 1 is elastic, less than 1 is inelastic, equal to 1 is unit elastic. Necessities such as salt and basic drugs tend to be inelastic; luxuries and goods with many substitutes tend to be elastic. If you remember only that, you can answer many conceptual questions.

National income: add the right items

Under the expenditure approach, national income is C + I + G + (X − M). Original example with hypothetical figures:

Consumption is ₦500 billion, investment ₦200 billion, government spending ₦150 billion, exports ₦100 billion, imports ₦80 billion. The GDP is: 500 + 200 + 150 + (100 − 80) = ₦870 billion.

Know the difference between GDP and GNP (GNP adds net income from abroad), between nominal and real figures (real is adjusted for price changes), and the three approaches (output, income, expenditure). Also know the problems of measuring national income, such as the informal sector and double counting.

Money, banking and public finance

Learn the functions of money (medium of exchange, unit of account, store of value, standard for deferred payment) and the ways inflation hurts or helps different groups. Understand what the Central Bank of Nigeria does as the banker to banks and the government, and the tools of monetary policy (interest rate, cash reserve ratio, open market operations).

For public finance, separate the types of tax (direct vs indirect, progressive vs regressive) with one example each. Be clear on the difference between budget deficit and surplus. Questions on the principles of taxation (equity, certainty, convenience, economy) are standard recall.

Use Nigerian examples, but not as answers

The subject is taught with local cases: cassava, cement, telecom, the naira exchange rate. Use them to remember. But in the exam, answer according to the definition, because the options are written in textbook terms. If an option says "rising prices of goods in general over time," that is inflation, even if your own story is about rice.

Common mistakes

1. Mixing up "demand" (willingness and ability to buy at each price) with "quantity demanded" (one point on the curve).
2. Treating a shift as a movement along the curve.
3. Using the average instead of the marginal in cost questions.
4. Forgetting the ceteris paribus assumption, which means "other things being equal".
5. Writing "elastic" for a necessity just because its price rose.

A study plan

For four weeks, give one block a week. In each week:

• Day 1 to 2: learn the definitions and draw the diagrams (demand and supply, cost curves).
• Day 3: do the calculations with at least five original or past-question sums.
• Day 4 to 5: 20 questions a day on the block, noting errors.
• Day 6: a timed mixed set.

Then do one week of mixed revision. For a longer list, read JAMB Economics topics to focus on. To learn how your score goals fit with your other three subjects, see how to score 300 in JAMB.

Practise on screen

ExamPadi has free JAMB Economics practice with explanations, plus a timed CBT mode. Begin with the 2025 JAMB Economics past questions. No resource can guarantee a score, but a steady cycle of definition, diagram, sum and past question builds the accuracy this subject asks for. Tonight, write the elasticity formula on a card and do five sums.
