NLTC Team · 17 September 2026 · 9 min read
Preparing for JAMB Chemistry? This practical guide explains the major areas to study, how to understand Chemistry concepts, use equations and calculations correctly, practise past questions and prepare effectively for JAMB 2027.
Chemistry is an important UTME subject for many students seeking admission into Medicine, Pharmacy, Nursing, Engineering, Biochemistry, Chemistry and other science-related courses. While some candidates see Chemistry as a difficult subject, effective preparation can make it much easier to understand and practise.
Preparing for JAMB 2027 Chemistry requires more than memorising definitions and chemical equations. You need to understand concepts, recognise patterns, perform calculations, interpret questions and apply what you have learned under examination conditions.
This guide provides a practical strategy you can use to prepare for JAMB Chemistry and improve your performance.
What Does JAMB Chemistry Test?
JAMB Chemistry questions can test both your theoretical knowledge and your ability to apply Chemistry principles to problems and calculations.
As part of your preparation, you should expect to study areas such as:
- Basic concepts of Chemistry
- Atomic structure and the periodic table
- Chemical bonding
- Mole concept and chemical calculations
- Stoichiometry
- States of matter
- Acids, bases and salts
- Redox reactions
- Electrochemistry
- Energy changes and chemical reactions
- Rates of reaction and chemical equilibrium
- Organic Chemistry
- Metals and their compounds
- Non-metals and their compounds
- Environmental and practical aspects of Chemistry
This list is intended as a preparation guide. Candidates should always consult the official JAMB syllabus for the 2027 examination when the relevant syllabus information is available.
1. Start With the Official JAMB Chemistry Syllabus
Before you begin studying topic after topic, find out exactly what you are expected to cover.
The official syllabus can help you break Chemistry into manageable sections instead of studying randomly. It also helps you identify topics that you have already covered and those that require more attention.
Use the JAMB IBASS e-Syllabus to check the official syllabus information available from JAMB.
Once you have the syllabus, turn it into a checklist. Tick off topics as you study and revisit them during revision.
2. Understand Chemistry Instead of Relying Only on Memorisation
There are many facts to remember in Chemistry, but memorising everything without understanding the underlying principles can become a problem when questions are presented differently.
For every topic, ask yourself:
- What does this concept mean?
- Why does the reaction occur?
- What are the important properties?
- What formulas or equations are involved?
- How could JAMB test this concept?
For example, when studying periodic trends, do not simply memorise isolated facts. Try to understand how properties change across periods and down groups and why those changes occur.
Understanding makes revision easier because you are connecting information rather than memorising unrelated facts.
3. Master the Mole Concept
The mole concept is one of the areas that many Chemistry students need to practise carefully because it connects several types of calculations.
Make sure you understand concepts such as:
- Relative atomic mass
- Relative molecular mass
- Moles
- Molar mass
- Number of particles
- Mass-to-mole calculations
- Simple stoichiometric relationships
Do not simply memorise formulas. Practise enough questions to recognise which information is provided and which quantity the question requires.
4. Practise Chemical Equations
Chemical equations are an important part of Chemistry preparation.
Learn to identify reactants and products and practise balancing equations correctly. You should also become familiar with the types of reactions associated with the topics you study.
When you see an equation in a question, pay attention to the coefficients because they can provide important information about the quantitative relationship between substances.
Regular practice will make balancing equations and interpreting chemical reactions much faster.
5. Give Organic Chemistry Serious Attention
Organic Chemistry can appear intimidating because of the number of compounds, names and reactions involved. The best approach is to organise the subject systematically.
Study important families of organic compounds and understand:
- Their general structures
- Naming patterns
- Functional groups
- Important properties
- Common reactions
- Relationships between related compounds
Rather than trying to memorise a huge list of unrelated reactions, group similar compounds together and understand their patterns.
6. Learn the Periodic Table Properly
The periodic table is much more useful when you understand how it is organised.
Revise the relationship between elements, their electronic structures and their chemical properties. Pay attention to trends across periods and groups and learn the important characteristics of commonly tested elements and their compounds.
You do not need to treat the periodic table as a collection of random information. Look for relationships between elements.
7. Practise Chemistry Calculations
Some candidates concentrate heavily on theory and neglect calculations. This can become a disadvantage because Chemistry questions can require you to apply formulas and numerical relationships.
Practise calculations involving areas such as:
- Moles and molar mass
- Stoichiometry
- Concentration
- Gas-related calculations
- Percentage composition
- Empirical and molecular formulae
- Other quantitative Chemistry relationships covered by the syllabus
For every calculation, first identify what you know and what you need to find. Then select the appropriate relationship before entering numbers into your calculator.
8. Use JAMB Past Questions as a Learning Tool
JAMB Chemistry past questions are valuable because they allow you to practise applying your knowledge to examination-style questions.
However, avoid turning past-question practice into answer memorisation.
When you get a question wrong, investigate the reason. Perhaps you misunderstood the concept, forgot a property, selected the wrong equation or made a calculation mistake.
Keep a record of your mistakes and review them regularly.
You can also incorporate regular question practice into your preparation through NLTC Online.
9. Learn to Distinguish Similar Chemistry Concepts
Some Chemistry questions are difficult not because the concepts are extremely complicated, but because several concepts appear similar.
During revision, create comparisons for topics that you often confuse.
For example, you might compare:
- Acids and bases
- Oxidation and reduction
- Strong and weak electrolytes
- Physical and chemical changes
- Homologous series and functional groups
- Exothermic and endothermic processes
Writing the differences in your own words can make these distinctions easier to remember.
10. Practise Interpretation of Tables, Graphs and Experimental Situations
Do not prepare for Chemistry by reading only paragraphs of notes.
Practise questions that require you to interpret information presented in tables, diagrams, graphs or descriptions of experiments.
Pay attention to observations, measurements, changes in colour, precipitates, gases, temperature changes and other information provided in experimental questions.
Always read the question carefully before deciding which Chemistry principle applies.
11. Build a Chemistry Mistake Book
A mistake book can become one of your most valuable revision resources.
Whenever you get a question wrong, write down:
- The topic involved.
- The question type.
- Your mistake.
- The correct principle or method.
- What you should remember next time.
Review this notebook regularly. If you repeatedly make the same type of mistake, that topic should receive additional attention in your study timetable.
12. Practise Chemistry Under CBT Conditions
JAMB is a computer-based examination, so your preparation should include computer-based practice.
Occasionally practise a set of Chemistry questions with a time limit. This helps you develop speed while maintaining accuracy.
Timed practice can also reveal whether you spend too much time on calculations or difficult questions.
The goal is to become comfortable answering questions efficiently without sacrificing accuracy.
How to Organise Your JAMB Chemistry Study
A simple weekly structure could look like this:
- Day 1: Study a new Chemistry topic.
- Day 2: Review the topic and solve practice questions.
- Day 3: Study calculations related to the topic.
- Day 4: Study another topic.
- Day 5: Attempt past questions.
- Day 6: Complete timed CBT practice.
- Day 7: Review mistakes, formulas and difficult concepts.
You can adjust the schedule according to your school timetable and the amount of time available for your other JAMB subjects.
Common Mistakes JAMB Chemistry Candidates Should Avoid
- Trying to memorise the entire subject without understanding it.
- Ignoring calculations until the final stage of preparation.
- Studying without following the syllabus.
- Memorising past-question answers.
- Failing to review incorrect answers.
- Confusing similar Chemistry concepts.
- Ignoring units in calculations.
- Spending too much time on one difficult question during CBT practice.
- Waiting until shortly before the examination to begin serious preparation.
How to Measure Your Chemistry Progress
Your preparation should become measurable as you progress.
Take practice tests periodically and record your scores. More importantly, analyse the questions you miss.
If you repeatedly lose marks in mole calculations, organic Chemistry or chemical bonding, do not simply take another random test. Go back to those topics and strengthen the underlying knowledge.
Over time, you should see improvements in both your accuracy and the amount of time required to answer questions.
