WAEC Chemistry covers organic, inorganic and physical chemistry. It is one of the most content-heavy subjects, but past questions reveal that certain reaction types, bonding concepts and periodic table questions dominate the paper year after year.
Students who score well in Chemistry typically spend extra time on organic chemistry reactions (substitution, addition, elimination, esterification) and mole calculations. These two areas alone account for roughly 30–40% of marks in most years.

How to Improve in Chemistry
- The mole concept underpins calculation questions across multiple topics — master this before moving on
- Draw out organic reaction mechanisms step by step, even in your head, before selecting an answer
- Electrolysis questions follow a predictable pattern — practise calculating quantities deposited using Faraday's law
- Always use timed mode — WAEC gives you roughly 40 seconds per question
- Read every explanation after submission — this is where the real learning happens
Questions About WAEC Chemistry
Organic chemistry reactions and mole calculations are the highest-yield areas. Learn all the functional group reactions (alcohols, carboxylic acids, esters, amines) and you will recognise them immediately in the exam. For inorganic chemistry, focus on periodic table trends and reactivity series.
Chemistry feels hard when studied as isolated facts. It becomes manageable when you understand the underlying principles — why atoms bond, why reactions happen, what drives equilibrium. Past questions help you see which principles are tested repeatedly so you can focus your energy.
Select any year from the grid above to start a timed practice session. The quiz mirrors the real WAEC CBT format — questions displayed one at a time, a countdown timer, and automatic answer saving. After you submit, you get a detailed results page showing your score, which questions you got wrong, and explanations for each answer.
