How to Study Mathematics for JAMB 2026/2027

1. Start With the Basics

Do not jump straight into difficult questions. Begin with foundational topics such as fractions, percentages, algebra and indices.

2. Understand the Formula

Before memorising a formula, understand what each symbol represents.

3. Solve Questions Every Day

Mathematics improves through practice. Even a small number of questions solved consistently can help you improve.

4. Keep a Formula Sheet

Write down important formulas and review them regularly.

5. Record Your Mistakes

Create a mistake notebook. Whenever you get a question wrong, write:

The question type
Your incorrect method
The correct method
Why you made the mistake

6. Practise Under Time

JAMB is a computer-based examination, so practise answering objective questions within a limited time.

7. Revise Difficult Topics

Do not avoid topics simply because they are difficult. Give extra time to areas where you consistently make mistakes.

How to Answer JAMB Mathematics Questions

Read the question carefully

Do not rush because one missed word can change the meaning of a problem.

Identify what is required

Determine whether the question asks for:

x
y
Percentage
Area
Volume
Probability
Ratio
Gradient
Mean
Another quantity

Choose the correct formula

Do not use a formula simply because it looks familiar.

Substitute carefully

Check every value before calculating.

Check the answer

If possible, substitute your answer back into the original equation.

Common Mistakes JAMB Mathematics Candidates Should Avoid

1. Memorising Without Understanding

Knowing a formula does not guarantee that you know when to use it.

2. Ignoring Units

Be careful when questions involve:

Metres
Centimetres
Kilometres
Square units
Cubic units

3. Rushing Calculations

A small arithmetic mistake can change the final answer.

4. Misreading Signs

Pay attention to:

Plus
Minus
Multiplication
Division
Positive numbers
Negative numbers

5. Ignoring Fractions

Fractions appear in many areas of Mathematics.

6. Depending on “Sure Questions”

There is no legitimate list that can guarantee the exact questions JAMB will ask. Use the syllabus as your guide.

JAMB Mathematics Past Questions

Past questions are useful for preparation because they help candidates become familiar with objective question formats and practise working under time pressure. Use them to:

Identify weak topics
Improve calculation speed
Practise formulas
Understand question patterns
Test your knowledge

However, past questions should not replace the current syllabus. A question that appeared previously may not appear again in exactly the same form. The best strategy is to understand the mathematical concept behind each question.
