Use this page as your JAMB Chemistry checklist. Read the table first, mark the topics you have covered, then use the explanations and study plan to turn the syllabus into weekly work.

What you should be able to do
Do not prepare by memorising isolated facts. You need to apply chemical principles, interpret tables and graphs, balance equations, calculate quantities and connect Chemistry to everyday materials and industry. For every topic, practise four skills: explain the idea, write the relevant equation, solve a numerical example and identify the laboratory observation.
1. Build the foundation first
Start with separation techniques: filtration, crystallisation, distillation, sublimation, chromatography and separating funnels. Know which physical property makes each method work. Then study laws of chemical combination, formulae, equations, relative masses, the mole, Avogadro’s constant, percentage composition, empirical formulae and reacting quantities.
For gases, understand particle motion and use Boyle’s, Charles’s, Dalton’s and the general gas equations correctly. Always convert temperature to kelvin where required and keep units consistent. In atomic structure, cover protons, neutrons, electrons, isotopes, electronic configuration, periodicity and ionic, covalent, metallic and coordinate bonding.
2. Study air, water and solutions as connected topics
Learn the composition and uses of air, including noble gases and air pollutants. For water, cover sources, treatment, hardness and methods of softening. In solubility, read and interpret solubility curves, distinguish saturated from unsaturated solutions and calculate solubility or crystallisation quantities. Connect environmental pollution to actual chemical substances, their sources, effects and control.
3. Make equations your working language
Acids, bases and salts require more than definitions. Identify strong and weak electrolytes, calculate simple pH values, select suitable indicators and understand salt preparation, hydrolysis and qualitative tests. In redox, assign oxidation numbers, identify oxidising and reducing agents and balance simple reactions. For electrolysis, predict products from the electrolyte, electrode type and concentration, then apply Faraday’s laws where calculations are required.
4. Understand why reactions behave differently
For energy changes, distinguish exothermic and endothermic reactions and work with enthalpy diagrams, bond energies and Hess’s law. For reaction rates, explain effects of concentration, pressure, surface area, temperature, light and catalysts using collision theory. For equilibrium, apply Le Chatelier’s principle instead of memorising directions. Ask what changed, which side reduces that change and how yield is affected.
5. Organise descriptive Chemistry
Create comparison sheets for hydrogen, halogens, oxygen, sulphur, nitrogen and carbon. Record preparation, properties, reactions, tests, uses and major compounds. Do the same for metals: occurrence, extraction, reactivity, corrosion, alloys and compounds. Learn trends and reasons; long disconnected lists are difficult to retain.
6. Master organic Chemistry by homologous series
Build a table for alkanes, alkenes, alkynes, benzene, alcohols, aldehydes, ketones, carboxylic acids, esters, amines and polymers. For each family, learn the functional group, general formula, naming, preparation, physical properties, characteristic reaction and chemical test. Practise drawing structures and distinguishing structural isomers.
High-risk areas
- Mole calculations: write the balanced equation before inserting numbers.
- Gas laws: identify constants and convert temperature to kelvin.
- Electrolysis: consider ions present, concentration and electrode type.
- Organic reactions: track functional-group changes and conditions.
- Qualitative analysis: connect reagent, observation and inference.
- Equilibrium: reason from the imposed change rather than guessing.
Six-week Chemistry study plan
- Week 1: separation, chemical combination, mole work and gas laws.
- Week 2: atomic structure, periodicity, bonding, air and water.
- Week 3: solubility, acids, bases, salts, redox and electrolysis.
- Week 4: energetics, rates and equilibrium.
- Week 5: non-metals, metals and qualitative analysis.
- Week 6: organic and industrial Chemistry, then timed mixed tests.
After each reading session, answer at least 20 objective questions without checking your notes. Review every wrong option and write the principle that makes it wrong. Add calculation drills three times each week.
Recommended preparation resources
Use the current official syllabus as your master checklist, one recognised senior secondary Chemistry textbook for explanations, a calculation-focused text and recent JAMB past questions. Do not replace the syllabus with a textbook’s chapter order: tick off the official topics directly.
Frequently asked questions
Is the periodic table provided in JAMB Chemistry?
Prepare to recognise common symbols, atomic numbers and trends without depending on a full table. Use any data supplied in the question carefully.
Does JAMB Chemistry include practical work?
Yes. Expect questions on apparatus, separation, preparation, observations, gas tests, titration ideas and qualitative analysis even though UTME is computer-based.
How should I improve calculations?
Write the formula or balanced equation, state known quantities with units, convert units, solve and check whether the answer is chemically sensible.
