Almost every Nigerian student collects past questions, but many use them badly. They read the questions and memorise answers someone else wrote, then panic when the lecturer changes the wording. Used properly, past questions show you what your lecturer considers important and train you to answer under pressure.
What past questions can tell you
- Topic frequency. List every question from the last four or five years by topic. Topics that appear almost every year deserve the most attention.
- Question style. Does the lecturer ask for definitions, calculations, diagrams, comparisons or essays? Practise in that style.
- Depth. A question worth 20 marks needs more than a definition. Look at the marks to judge how much detail is expected.
- Command words. "State" wants a short answer. "Explain" wants reasons. "Discuss" wants several points with examples. "Evaluate" wants strengths, weaknesses and a conclusion.
A better way to practise
- Learn the topic first. Do not start past questions on a topic you have never studied. You will only end up memorising.
- Attempt without help. Write your own answer before looking at any solution, even if it is incomplete.
- Check against your notes and textbook, not just the circulating "solutions", which are often wrong.
- Rewrite your weak answers properly. The rewriting is where the learning happens.
- Repeat a week later. Try the same questions again without notes and see what stuck.
Common mistakes
- Memorising answers word for word. Lecturers often reword questions or change numbers. Understand the method so you can handle any version.
- Only studying topics that appeared before. Past questions show patterns, not guarantees. Cover the full course outline, then use past questions to decide where to go deeper.
- Trusting every solution. Solutions passed around in class groups are often copied from one person and contain errors. Verify them.
- Never timing yourself. Knowing an answer is not enough if you cannot write it in the time allowed.
Turning past questions into a study plan
Make a simple table with three columns: topic, how many times it appeared, and how confident you feel. Topics that appear often and where you feel weak go to the top of your list. Topics that rarely appear and where you feel strong go to the bottom.
For calculation courses
In courses like mathematics, statistics, accounting and physics, solve every past question fully, including the arithmetic. Write down the formula, show each step and include units. Many students lose marks not because they do not know the method but because they skip steps or make arithmetic errors under time pressure.
Past questions are a mirror of the exam. Use them to practise thinking, not to memorise someone else's thinking, and you will be ready for whatever version of the question appears.
