2026 IJMB Past Questions and Answers PDF Free Download
If you are preparing for the IJMB examination in 2026, the single most useful thing you can do right now is study past questions. Not because the same questions repeat word for word, but because the examiners work within a pattern. Once you understand that pattern, the exam becomes predictable.
This page covers the 2026 IJMB past questions and answers for every major subject — with analysis of what each paper tests, which topics come up most, and how to answer them correctly. You can download all materials from the FreshNote library or practice them directly online.

What the IJMB Examination Actually Tests
IJMB is moderated by Ahmadu Bello University, Zaria, and it is an A-Level equivalent programme. This means the questions are set at a level above WAEC and NECO. They do not ask you to recall definitions alone — they ask you to apply, analyse, and explain.
Each subject is divided into two papers: Paper 1 (objective/multiple choice) and Paper 2 (theory/essay). The theory section carries more marks and requires structured written answers. Students who only practice objective questions regularly underperform in the theory section because they are unprepared for the depth required.
The 2026 diet follows the same structure as previous years. Below is a subject-by-subject breakdown of what the past questions reveal.
IJMB Mathematics — Past Questions Analysis
Mathematics is the subject with the most consistent pattern in IJMB history. If you study past questions from 2018 to 2025, you will notice the same clusters of topics appearing year after year.
Calculus is tested in almost every diet. Questions cover differentiation from first principles, the chain rule, product rule, quotient rule, and integration by substitution and by parts. A common question type asks candidates to find the stationary points of a curve and determine their nature using the second derivative test.
Coordinate geometry features regularly, especially equations of straight lines, circles, and the conditions for tangency. Candidates are often asked to find the equation of a circle given three points, or to determine whether a given line is a tangent, secant, or misses a circle entirely.
Sequences and series — particularly arithmetic progressions, geometric progressions, and the binomial theorem — appear in theory questions. The binomial theorem questions in recent years have required candidates to find specific terms and apply the expansion to approximate values.
Trigonometry questions focus on compound angle formulae, the factor formulae, and solving trigonometric equations within given ranges. Many candidates lose marks here because they forget to list all solutions within the specified interval.
Matrices and determinants appear in Paper 2, often requiring candidates to solve simultaneous equations using Cramer's rule or matrix inversion.
Vectors in two and three dimensions are tested, including scalar products and the angle between two vectors.
The marking scheme in IJMB Mathematics rewards method. Even if your final answer is wrong, you earn marks for correct working. Always show every step clearly.
IJMB Physics — Past Questions Analysis
Physics past questions in IJMB follow a clear division between mechanics, waves, electricity, and modern physics. Each section appears in both objective and theory papers.
Mechanics dominates the early parts of Paper 1. Questions cover Newton's laws of motion, projectile motion, work-energy theorem, conservation of momentum, and circular motion. A common theory question asks candidates to derive an expression for the range of a projectile or to explain why a satellite does not need a constant force to maintain orbit.
Waves and optics questions test interference, diffraction, polarisation, and the behaviour of light at boundaries. Young's double slit experiment is a favourite — candidates are regularly asked to calculate fringe width or wavelength from given data. Total internal reflection and critical angle calculations appear almost every year.

Electricity and magnetism form a large portion of the paper. Topics include Ohm's law, Kirchhoff's laws, capacitors in series and parallel, electromagnetic induction, and the transformer equation. Theory questions often require circuit analysis using Kirchhoff's laws, and candidates are expected to derive expressions as well as calculate values.
Thermodynamics questions test the laws of thermodynamics, ideal gas laws, and the kinetic theory of gases. Candidates are asked to distinguish between isothermal, adiabatic, and isobaric processes, and to interpret p-V diagrams.
Modern physics — including photoelectric effect, radioactive decay, half-life calculations, and nuclear reactions — appears consistently in the final section of the paper. Half-life calculations are highly formula-dependent and candidates who do not memorise the decay equation lose straightforward marks.
In Physics, drawing clear and well-labelled diagrams in theory answers often earns additional marks even when working is incomplete.
IJMB Chemistry — Past Questions Analysis
Chemistry past questions cover physical, inorganic, and organic chemistry in roughly equal proportion. The examiners test both calculation ability and conceptual understanding.
Physical chemistry questions focus on stoichiometry, mole concept, gas laws, thermochemistry, chemical equilibrium, and electrochemistry. Calculation questions on mole ratios, percentage yield, and empirical formula are standard. In equilibrium chemistry, candidates are asked to write expressions for Kc and Kp and to explain the effect of changes in temperature, pressure, and concentration using Le Chatelier's principle.
Inorganic chemistry tests the periodic table trends — atomic radius, ionisation energy, electronegativity, and electron affinity — alongside the chemistry of specific groups. Group I and Group II elements appear frequently, as does the chemistry of nitrogen, sulphur, chlorine, and their compounds. Questions on the industrial manufacture of ammonia (Haber process) and sulphuric acid (Contact process) appear in almost every diet.
Organic chemistry is where many students struggle. IJMB questions cover homologous series, functional group identification, reaction mechanisms, and multi-step synthesis. The reactions of alkanes, alkenes, alkynes, alcohols, carboxylic acids, esters, and amines are all examinable. Theory questions often present a reaction scheme and ask candidates to identify intermediates, name reaction types, or predict products.
Practical questions in Paper 2 sometimes ask candidates to describe experiments — titration procedures, tests for ions, and identification of organic compounds using reagents like Fehling's solution, Tollens' reagent, and Lucas reagent.
Chemistry rewards candidates who understand why reactions happen, not just what happens. Explaining mechanisms and reaction conditions earns marks that pure memorisation cannot.
IJMB Biology — Past Questions Analysis
Biology past questions in IJMB test candidates across cell biology, genetics, ecology, physiology, and evolution.
Cell biology questions cover cell structure and function, differences between prokaryotic and eukaryotic cells, cell division (mitosis and meiosis), and membrane transport. Theory questions often require candidates to compare the stages of mitosis and meiosis and explain the significance of each process.
Genetics is one of the most heavily tested areas. Questions cover Mendelian inheritance, co-dominance, sex-linked traits, gene linkage, and the Hardy-Weinberg principle. Dihybrid cross problems appear regularly, and candidates are expected to construct Punnett squares and calculate expected phenotypic ratios.
Physiology questions test the functioning of major systems — circulatory, respiratory, excretory, nervous, and endocrine. A common question type asks candidates to trace the pathway of blood through the heart and lungs, or to explain how the kidney regulates water balance through the renin-angiotensin-aldosterone system.
Ecology questions focus on population dynamics, food webs, energy flow through ecosystems, and the nitrogen, carbon, and water cycles. Candidates are often asked to explain the concept of ecological succession and distinguish between primary and secondary succession.
Evolution and taxonomy round out the paper. Questions on natural selection, speciation, and the classification of organisms appear in Paper 2. Candidates are expected to explain Darwin's theory of evolution by natural selection and evaluate the evidence supporting it.
Biology answers in theory should be precise. Examiners dock marks for vague language — saying "the blood flows to the heart" earns less than correctly naming the specific chamber and vessel involved.
IJMB Economics — Past Questions Analysis
Economics past questions test microeconomic theory, macroeconomic concepts, and Nigerian economic issues.
Microeconomics questions cover demand and supply analysis, elasticity, consumer theory, production theory, cost analysis, and market structures. Calculation questions on price elasticity of demand and supply are common in Paper 1. Theory questions often ask candidates to explain and illustrate the effect of a shift in demand or supply on equilibrium price and quantity.

Market structures — perfect competition, monopoly, oligopoly, and monopolistic competition — are examined through both diagrammatic analysis and written explanation. Candidates are expected to draw and interpret cost and revenue diagrams, and to explain long-run equilibrium in competitive markets.
Macroeconomics questions cover national income accounting, inflation, unemployment, monetary policy, fiscal policy, and balance of payments. Questions on the multiplier effect and the Keynesian income-expenditure model appear in theory papers. Candidates are also tested on the instruments of monetary policy — open market operations, reserve requirements, and discount rate changes.
Nigerian economic issues appear in Paper 2 and test candidates' knowledge of the Nigerian economy — oil dependency, trade policy, agricultural development, and structural adjustment. These questions require candidates to apply economic principles to real Nigerian contexts.
Diagrams are compulsory in Economics. A theory answer on market structures or national income without a properly labelled diagram is considered incomplete.
IJMB Government — Past Questions Analysis
Government past questions test political concepts, Nigerian constitutional history, comparative government, and international relations.
Political concepts tested include sovereignty, legitimacy, separation of powers, federalism, democracy, and political parties. Theory questions ask candidates to define and analyse these concepts, often with reference to examples from Nigeria and other countries.
Nigerian constitutional history is extensively tested. Questions cover the Richards Constitution of 1946, the Macpherson Constitution of 1951, the Lyttleton Constitution of 1954, the Independence Constitution of 1960, and the Republican Constitution of 1963. Candidates are asked to highlight the key provisions of each constitution and assess its impact on Nigerian political development. The 1979 and 1999 constitutions also feature prominently, particularly on federalism, the structure of government, and fundamental rights.
Comparative government questions ask candidates to compare presidential and parliamentary systems, unitary and federal systems, and written and unwritten constitutions. The governments of the United Kingdom, United States, France, and Russia are commonly referenced.
International relations questions cover the United Nations, African Union, ECOWAS, and Nigeria's foreign policy. Theory questions often ask candidates to assess the role of ECOWAS in maintaining peace and stability in West Africa, or to evaluate Nigeria's foreign policy since independence.
Government theory answers are stronger when they use specific dates, constitutional provisions, and named political figures rather than general statements.
IJMB Literature-in-English — Past Questions Analysis
Literature past questions are divided into three areas: prose, drama, and poetry — with African and non-African texts represented in each category.
Prose questions ask candidates to analyse character, theme, setting, and narrative technique in prescribed texts. IJMB has used texts such as Chinua Achebe's Things Fall Apart, Wole Soyinka's The Interpreters, and various non-African novels. Questions require close reference to the text and the ability to quote accurately.
Drama questions focus on tragic and comic structures, dramatic irony, conflict, and resolution. Candidates are expected to understand how staging, dialogue, and action work together. Questions often ask candidates to discuss how a playwright creates tension at a specific point in the play.
Poetry questions test the ability to analyse form, imagery, tone, diction, and meaning. Unseen poem questions appear in Paper 1, requiring candidates to read a poem they have not studied before and answer questions on it. This tests reading comprehension and literary analysis skills simultaneously.
Literature rewards candidates who write with precision and support every point with textual evidence. Stating a theme without illustrating it from the text earns minimal marks.
IJMB Sociology — Past Questions Analysis
Sociology past questions test sociological theory, social institutions, research methods, and contemporary social issues.
Sociological theories — functionalism, conflict theory, symbolic interactionism, and feminism — are examined in both objective and theory papers. Candidates are expected to explain each theoretical perspective and evaluate its strengths and limitations.
Social institutions tested include the family, education, religion, economy, and the state. Theory questions often ask candidates to apply a sociological theory to explain the function of a specific institution — for example, how functionalists explain the role of education in society versus how conflict theorists interpret the same institution.
Research methods questions cover quantitative and qualitative approaches, sampling techniques, data collection methods, and ethical considerations in research. Candidates are asked to distinguish between primary and secondary data, explain the advantages and disadvantages of interviews versus questionnaires, and assess the validity and reliability of sociological research.
Contemporary social issues in Nigeria — urbanisation, poverty, crime, ethnic conflict, and gender inequality — feature in Paper 2. Candidates are expected to apply sociological concepts to analyse these issues and suggest policy responses.
How to Download the 2026 IJMB Past Questions
All past questions and answers covered on this page are available in the FreshNote library. You can download subject-specific PDFs or access them online through the FreshNote CBT practice system, which allows you to attempt questions under timed exam conditions.
To download:
Visit freshnote.com.ng and navigate to the IJMB section. Select your subjects. You can access free sample papers immediately without creating an account. Full question banks with worked solutions are available to registered users.
The online practice system is recommended for candidates who want to simulate actual exam conditions, track their scores, and identify weak topics before the exam date.
How Long Before the Exam Should You Start Practising?
The honest answer is: as early as possible, but at minimum three months before the exam. One month is not enough time to cover all subjects thoroughly and still have time to revisit weak areas.
A realistic study plan looks like this: spend the first month reading your textbooks topic by topic. Spend the second month solving past questions topic by topic, matching questions to what you have read. Spend the third month doing full timed past papers under exam conditions and reviewing your mistakes.
Candidates who follow this pattern consistently perform better than those who cram in the final weeks.
Final Note
IJMB is a serious A-Level examination and the past questions on this page reflect that standard. The analysis above is not a shortcut — it is a map. The actual work of reading, understanding, and practising still belongs to you.
Study each subject with its past questions open beside you. When you finish a topic in your textbook, immediately test yourself with related past questions. That cycle of study and testing is what actually builds exam-ready knowledge.
