WAEC Repeated Topics: Subjects and Concepts That Show Up Every Year

Certain topics appear in WAEC with remarkable consistency. Knowing them gives you a study advantage. Here is what to focus on subject by subject.

English Language: Essay types include argumentative, narrative, and letter writing (formal and informal). Comprehension passages often test inference and vocabulary. Summary writing is a constant feature. Lexis and structure focus on concord, idioms, and phrasal verbs. Mathematics: Sets, surds, quadratic equations, variation, inequalities, geometry (circle theorems, constructions), trigonometry, statistics (mean, median, mode, probability), and mensuration. Graph questions are compulsory.

Biology: Cell structure, nutrition, respiration, excretion, reproduction (plants and animals), ecology, genetics, and evolution. Diagrams are heavily tested, especially the eye, ear, heart, and flower parts.

Chemistry: Atomic structure, periodic table trends, chemical bonding, electrolysis, organic chemistry (alkanes, alkenes, alcohols, esters), salts, and rates of reaction. Practicals often involve titration and salt analysis.

Physics: Mechanics (motion, forces, energy), waves (sound and light), electricity (Ohm’s law, circuits), and electromagnetism. Calculations and definitions are key. Graphs are frequently used. Economics: Demand and supply, production, cost and revenue, national income, money and banking, inflation, and international trade. Diagrams are essential for scoring high. Government: Types of government, constitutions, organs of government, political parties, electoral systems, and Nigerian political history from the First Republic to present. Literature-in-English: Prescribed texts change every three years, but the style of questions—character analysis, themes, and literary devices—remains constant.

Use this list as a checklist. Master these topics first. Then expand to other areas. Solve past questions from 2010 to 2026. You will see the pattern clearly.
