10 Mistakes Nigerian Students Make in WAEC (And How to Avoid Them)
PassVerse Team
10 January 2025
Every year, hundreds of thousands of Nigerian students sit the WAEC May/June WASSCE. And every year, a significant number fail — not because they lack intelligence, but because of predictable, avoidable mistakes.
WAEC's own data shows that failure rates in core subjects like Mathematics and English hover between 40–60% in many years. Most of those failures trace back to a handful of recurring errors in preparation and exam strategy.
This article names those errors and tells you exactly what to do instead.
1. Not Practising Past Questions
This is the number one mistake, and it causes more failures than everything else on this list combined.
WAEC is not an unpredictable exam. It has consistent patterns, recurring question types, and predictable topic weightings. Students who practise 5 years of WAEC past questions enter the hall having already seen similar questions. Students who only read textbooks enter the hall seeing question styles they have never encountered.
How to fix it: Start practising past questions from the day you start revision — not after you feel "ready." Use an app like PassVerse that organises questions by subject and topic with detailed answers. Target at least 300 past questions per subject before exam day.
2. Ignoring the Marking Scheme
WAEC publishes Chief Examiners' Reports after every sitting. These reports explicitly state what students got wrong, what markers expected, and what kinds of answers earned full marks.
Most students have never read a WAEC Chief Examiner's Report in their lives. This is a massive missed opportunity.
How to fix it: Whenever you practice essay or theory questions, compare your answers to the marking scheme — not just to see if you are "right" but to understand the level of detail expected. WAEC markers are trained to award marks for specific points. If those points are not in your answer, you do not get the marks.
3. Poor Time Management in the Exam Hall
Many WAEC students run out of time in essay papers. They spend 40 minutes on one question and rush through (or skip) the remaining four.
The Mathematics essay paper is a classic example. Students see a hard question first, plant their feet, and fight it for 30 minutes. Meanwhile, three easier questions sit untouched.
How to fix it: Before every practice session, time yourself. For WAEC essay papers, divide the time by the number of questions and add a small buffer for reading and checking. In the exam, move on from a hard question. You can return at the end. A partial answer on five questions beats a perfect answer on three.
4. Cramming the Night Before
The night before a WAEC paper is the worst possible time to introduce new material to your brain. Memory consolidation happens during sleep. Information crammed at 2 AM is poorly consolidated and often unavailable under exam pressure.
Students who cram the night before also arrive at the exam hall tired, anxious, and cognitively impaired — exactly the opposite of what you need.
How to fix it: Use the night before for light review only — going over your notes, reading key formulas, refreshing yourself on things you already know. Be in bed by 10 PM. A rested brain outperforms a tired, overloaded one every time.
5. Skipping Practicals (Science Students)
Biology, Chemistry, and Physics all have practical components in WAEC. These carry significant marks. Yet many students spend their entire preparation period on theory and completely ignore practicals.
In biology practicals, examiners look for specific observational language and correct identification of specimens. Students who have never handled a compound microscope, or never labelled a dissection, struggle with questions that prepared students find easy.
How to fix it: Attend all practical classes at your school. If your school has poor lab resources, use your WAEC past practical questions to at least understand what is expected. Know common specimens, apparatus, and standard observations.

6. Not Reading Questions Carefully
This sounds obvious. Yet in every WAEC session, a significant proportion of marking errors trace back to misread questions. WAEC examiners use precise language deliberately:
- "State" vs "Explain" — stating requires a one-line fact; explaining requires the reason behind it
- "Describe" vs "Define" — defining is brief and technical; describing can be more expansive
- "Which of the following is NOT" — the word NOT reverses the entire question
- "Give TWO examples" — giving one means half marks; giving three means the marker may only mark the first two
How to fix it: In every practice session, underline the instruction word before answering. Train yourself to do this automatically. In the actual exam, read each question twice before writing.
7. Leaving Blank Answers
WAEC Objective papers do not penalise wrong answers. Every blank is a guaranteed zero. Every guess is a 25% chance.
This sounds simple but students frequently leave blanks out of uncertainty or because they run out of time.
How to fix it: Never leave an Objective question blank. If you have no idea, eliminate one or two obviously wrong options and guess between the rest. For theory questions, write something — any relevant point may earn a mark. "Partial marks" are real and they matter.
8. Ignoring Weak Subjects
Many students protect their self-esteem by spending all their time on subjects they are good at. This feels productive but is counterproductive.
If you score 90 in Government and 35 in Mathematics, studying Government more does not help your aggregate. Every hour you spend on your weak subject returns far more aggregate improvement than the same hour spent reinforcing your strong subject.
How to fix it: After identifying your weakest subject, give it the first study session of every day — when your energy is highest. Do not allow yourself to skip it because it is uncomfortable. Growth happens in discomfort.
9. Not Practising CBT Format
Some WAEC subjects now include CBT components and more schools are using digital exam formats. Students who have only ever practised on paper can struggle with the CBT interface, losing valuable time navigating menus.
Even for paper-based WAEC, practising on a digital platform like PassVerse trains the mental habit of reading on screen, navigating quickly between questions, and managing digital timers.
How to fix it: Practice on digital platforms throughout your preparation, not just in the final week. Familiarity with the format removes one source of exam anxiety.
10. Starting Preparation Too Late
This is the mistake that makes all the other mistakes irrelevant, because there is not enough time to fix them.
Many students begin serious WAEC preparation only 4–6 weeks before the exam. That is not enough time to cover a full syllabus, practise sufficient past questions, identify weak areas, address those weaknesses, and consolidate everything.
The students who consistently score As begin 4–6 months before the exam. Not by studying harder, but by studying earlier.
How to fix it: If you have not started yet, start today. Not next week, not after the next holiday. Every day earlier you start is compounded into better preparation by exam day.
Conclusion
Failing WAEC is not a verdict on your intelligence. It is almost always the result of one or more of the avoidable mistakes above. The great news is that every mistake on this list has a clear, practical solution.
You are reading this article, which means you are already doing something the students who fail do not do: you are actively seeking better strategies.
Now act on them. Practise past questions. Study your weak subjects first. Sleep before the exam. Read every question carefully.

Frequently Asked Questions
Q: How many times can I resit WAEC if I fail? A: WAEC offers November/December resits (GCE) every year. There is no limit to the number of times you can sit WAEC, though most universities have age-of-result requirements.
Q: Does WAEC penalise for wrong answers? A: For Objective (multiple-choice) papers, WAEC does not penalise wrong answers. Always attempt every question.
Q: How many subjects should I sit in WAEC? A: Most students sit a minimum of 8–9 subjects to maximise their university admission options. However, universities typically require a minimum of 5 credits including English and Mathematics.
