For many Nigerian graduate programmes and entry-level jobs, the aptitude test is the first real hurdle. Banks, FMCG companies, oil and gas firms, consulting firms and many public agencies use timed tests to narrow thousands of applicants to a shortlist. You can have a strong CV and still be screened out if you are not prepared. The good news: aptitude tests reward practice. This guide explains the common test types, how they are delivered in Nigeria, and a step-by-step preparation plan.
What aptitude tests measure
Aptitude tests aim to measure how you reason, not what you memorised in school. Most employer tests include some combination of:
- Numerical reasoning: interpreting tables and charts, percentages, ratios, and basic arithmetic under time pressure.
- Verbal reasoning: reading a passage and deciding whether a statement is true, false or cannot be determined from the text.
- Abstract or logical reasoning: spotting patterns in shapes or sequences.
- Situational judgement tests (SJTs): choosing the most and least effective responses to workplace scenarios.
- Personality questionnaires: describing your preferences and work style.
- Role-specific tests: for example, accounting questions, coding challenges or English grammar.
How tests are delivered
- Online, unsupervised: you receive a link and complete the test at home within a deadline.
- Proctored online: a webcam monitors you while you take the test.
- Test centre: computer-based tests at a centre, common for large graduate intakes and some public sector recruitment.
Read invitation emails carefully: they usually state the test type, time limit, whether calculators are allowed, and technical requirements.
Step 1: Find out which test you’re taking
Invitation emails often name the test provider or describe the sections. Search for the employer’s assessment process on its careers page, and ask people who went through the same programme in previous years what to expect. Knowing the format lets you practise the right type.
Step 2: Refresh core numerical skills
Most numerical tests use secondary-school maths applied quickly. Revise:
- percentages, percentage change and percentage points;
- ratios and proportions;
- averages;
- currency conversion and unit rates;
- reading values from tables, bar charts and pie charts.
Practise mental shortcuts: 10% is divide by 10; 5% is half of that; 15% is the two added. Being quick at estimates helps you eliminate wrong options fast.
Mini example
A company’s revenue rose from ₦40 million to ₦46 million. What is the percentage increase? Change = ₦6 million; ₦6m ÷ ₦40m = 0.15, so 15%. Notice the trap: if the question asks for the percentage of the new figure, the answer would be different.
Step 3: Master verbal reasoning logic
In “True / False / Cannot Say” questions, the rule is to use only the passage, not your outside knowledge.
- True: the statement follows directly from the passage.
- False: the passage contradicts the statement.
- Cannot Say: the passage doesn’t give enough information either way.
Watch qualifiers like “all”, “some”, “most”, “always” and “never”. A statement saying “all” when the passage says “most” is usually false or cannot say.
Step 4: Practise abstract reasoning
For pattern questions, check one rule at a time: number of shapes, colour or shading, rotation, position, size. Write down the rules you test so you don’t go in circles. Speed comes with exposure, so do short daily sets rather than one long session.
Step 5: Prepare for situational judgement tests
SJTs reflect the employer’s values. Read the company’s stated values on its website. In general, the best responses are professional, honest, proactive and respectful of colleagues and customers. Avoid options that ignore problems, pass blame or break rules, even if they seem convenient.
Step 6: Be honest on personality questionnaires
Trying to guess the “right” answer usually backfires, because questionnaires often check consistency. Answer honestly, while keeping the role in mind.
Step 7: Practise under timed conditions
Time pressure is what makes aptitude tests hard. Practise with a timer that matches the real test. Many test publishers and career services offer free sample tests; use these to learn the format. Track your score and average time per question each week.
A four-week preparation plan
| Week | Focus | Daily time |
|---|---|---|
| 1 | Diagnose: take one sample test of each type; revise numerical basics. | 45–60 minutes |
| 2 | Numerical and verbal practice sets with explanations. | 60 minutes |
| 3 | Abstract reasoning and SJTs; timed mixed sets. | 60 minutes |
| 4 | Full timed mock tests; review mistakes; rest the day before. | 60–90 minutes |
Put the plan in your diary so it actually happens. The 2027 Printable Planner has weekly pages where you can schedule study blocks around work or NYSC.
Test-day checklist
- Online tests: stable internet and a backup connection, a charged laptop or power backup, a quiet room, calculator if allowed, scrap paper and pen.
- Test centre: confirm the address the day before, plan transport with buffer time for traffic, carry the required ID and printed invitation.
- Read instructions carefully before starting the timer.
- Don’t get stuck: skip and return if allowed. Check whether wrong answers are penalised before guessing.
Integrity matters
Do not let anyone take an online test for you, and don’t buy “leaked answers”. Many employers retest shortlisted candidates in person, and cheating can lead to disqualification or later dismissal.
Beware of recruitment scams
Be wary of anyone asking you to pay to sit a test, to “secure a slot” or to guarantee success. Genuine employers do not charge candidates for aptitude tests. Verify invitations through the official company website or email domain.
After the test
If you pass, the next stages are usually interviews or an assessment centre. Our graduate interview tips cover what to expect. Keep your CV sharp too; see our ATS-friendly CV guide and the CV Templates Pack.
Common mistakes that cost candidates
- Starting the test unprepared. Many candidates open the link the moment it arrives, on a phone, with poor network. Wait until you are ready, but respect the deadline.
- Spending too long on one question. Divide the time by the number of questions to know your average budget per question, and move on when you exceed it.
- Misreading units. Charts may show figures in thousands or millions, or percentages versus actual values. Check headings and footnotes before calculating.
- Bringing outside knowledge into verbal tests. If the passage doesn’t say it, the answer is usually “Cannot Say”.
- Practising only the easy sections. Most people prefer the section they are already good at. Spend more time on your weakest area.
Tracking your progress
Keep a simple log after each practice session: date, test type, number correct, total questions and time used. After two weeks, you will see which sections are improving and where you still lose marks. Review every wrong answer and write one line explaining why it was wrong. That habit turns practice into learning, and it is what separates candidates who plateau from those who keep improving.
Frequently asked questions
Can I use a calculator?
It depends on the test. Many online numerical tests allow one; check the instructions in your invitation.
How long are aptitude tests?
Each section is often short, but timing varies by employer and provider. The invitation usually states it.
Are aptitude tests the same for every company?
No. Formats and difficulty vary, but the core skills are similar, so general practice transfers well.
What if I fail?
Review which section let you down, practise that area, and apply again. Some employers set a waiting period before reapplying.
Do public sector jobs use aptitude tests?
Many public agencies use computer-based tests in recruitment. Follow official announcements only.
