NECO BECE common mistakes
NECO BECE · Understand the traps and how to avoid them.
In Mathematics, writing only the final answer with no working, so method marks are lost even when the answer is right, and no partial credit is earned when it is wrong.
Candidates practise for objective (multiple-choice) papers where only the letter matters, then carry the same habit into the theory paper, where NECO awards marks for correct steps, correct formula substitution, and correct units.
What to do instead
In every practice theory question, write the formula, then the substitution line, then the working, then the answer with units, and check against a marking scheme that shows step marks. Time yourself so working fits the paper's time budget.
In English Studies, choosing an answer option that is grammatically possible but does not fit the passage's meaning in comprehension and summary items.
Candidates skim the passage, recognise a word from the options, and pick it without checking the sentence in context; summary items then reproduce whole sentences instead of stating the required points in the candidate's own words.
What to do instead
Read the questions before the passage, then read the passage twice. For each option, locate the exact line that supports or rules it out. For summary, draft the points in short phrases, count the points the question asks for, and rewrite them in your own words within the word limit.
In Basic Science and Technology, describing a science process using everyday words instead of the correct technical term, for example saying 'water vapour turns back to water' without naming condensation.
Candidates memorise definitions without linking them to the experiments and examples taught in class, so under exam pressure they describe the phenomenon but cannot supply the term the mark scheme requires.
What to do instead
Build a two-column list per topic: term on the left, one-line definition plus one familiar example on the right. Test yourself by covering the term column and naming the term from the definition and example.
In Business Studies, confusing bookkeeping entries, for example recording a purchase of goods on credit as a debit to the purchases account only, without the matching credit to the supplier's account.
Candidates learn definitions of debit and credit but do not practise the double-entry rule on real transactions, so they treat each transaction as a single line rather than two equal and opposite entries.
What to do instead
Practise ten transactions a day using the rule 'every debit has a credit'. For each transaction, name the two accounts affected, state which is debited and which is credited, and confirm the two sides balance before moving on.
In Social Studies, giving a personal opinion or a moral judgement where the question asks for a factual explanation of a civic or social issue.
The subject invites discussion, and candidates answer from personal experience rather than from the concepts (for example, rule of law, human rights, or socialisation) taught in the syllabus.
What to do instead
For every topic, memorise three or four key concepts with a one-sentence definition and a Nigerian example. In answers, open with the concept, then explain, then give the example, and avoid words like 'I think' or 'it is bad'.
In Agricultural Science, naming a crop or animal disease without stating the causal organism, the symptom, and the control measure the question asks for.
Candidates revise disease names in isolation and do not practise the four-part structure (cause, symptom, effect, control) that structured questions reward.
What to do instead
Make a disease table with columns for crop or animal, causal organism, visible symptoms, effect on yield, and control. Cover columns and recite them, then answer past structured questions in full sentences using all four parts.
In Computer Studies, defining a hardware device or software type by brand name only, for example answering 'it is like an HP laptop' instead of naming and describing the component's function.
Candidates learn from devices they use rather than from the syllabus categories (input, output, storage, processing), so they cannot classify or explain unfamiliar items in the question.
What to do instead
Learn the four function categories with three examples each, and for every device write one line on what it does and where it sits in the categories. Practise classifying devices you have never used from a written description alone.
In Civic Education, treating the subject as general knowledge and answering questions on national values, rights, and duties with vague slogans rather than specific constitutional or civic content.
Candidates assume the paper repeats everyday talk about good behaviour and do not study the defined terms, agencies, and duties in the syllabus.
What to do instead
Prepare a glossary of civic terms with precise definitions and one Nigerian example each (for example, an agency and its function). Answer past questions in the pattern: define, explain, give example, state importance.
Across all papers, misreading the instruction words, for example writing a full essay where the question says 'list' or giving one word where it says 'explain'.
Candidates read only the topic of the question and not the command word, so the length and depth of the answer do not match what the marking scheme rewards.
What to do instead
Before answering, underline the command word and the number of points required. Learn what each command word demands (list means brief points, explain means reasons, describe means features), and check your answer against that word before moving on.
Managing time badly: spending most of the time on the first few questions or on one long essay, then leaving later questions blank or rushed.
Candidates answer in the order printed rather than the order that suits them, and they do not practise under timed conditions, so they misjudge how long a question takes.
What to do instead
In practice, divide the total minutes by the number of questions to get a per-question budget, answer the easiest questions first to bank marks, and leave a short gap at the end for checking. Do at least two full timed mock papers before the exam.
