How to Prepare for University Exams

Learning how to prepare for university exams is easier when revision starts before the final few days. A useful exam preparation plan gives you time to understand difficult topics, practise what you have learned and identify gaps before the exam.

For students in Nigerian universities, the best approach also needs to fit around lectures, assignments, tests, practical work and the academic calendar. You do not need to study every subject for the same amount of time. Start with the topics that need the most attention and build a realistic revision routine.

Start by checking what the exam covers

Before you begin revising, find out what you are expected to know. Check your course outline, lecture notes, prescribed texts, lecturer’s instructions and any available revision guidance.

Make a list of the topics for each course. Mark each topic as strong, uncertain or difficult. This gives you a starting point instead of spending the first days of revision deciding what to study.

Build an exam revision plan

Write down your exam dates and work backwards from the first paper. Give each subject several revision sessions rather than leaving it until the night before.

A simple plan might include:

• Reviewing lecture notes
• Reading difficult topics
• Practising questions
• Testing yourself without looking at your notes
• Reviewing mistakes
• Taking short breaks

Leave some flexible time for topics that take longer than expected. A timetable that has no room for changes can become difficult to maintain.

Use active recall instead of only rereading

Rereading notes can make familiar material feel easier without showing whether you can actually remember it. Active recall requires you to retrieve information from memory.

Close your notes and try to explain a concept in your own words. Write down everything you can remember about a topic, answer questions without checking the solution first or create short questions from your notes.

When you check your answer, focus on what you could not remember. That becomes a useful target for your next revision session.

Practise with past questions when they are available

Past examination questions can help you understand the style and level of questions you may encounter. They are particularly useful when you use them as practice rather than simply reading the answers.

Try to answer a question under realistic conditions. Then compare your work with the available marking guide, lecturer’s solution or reliable course material.

Do not assume that an old question will appear again. Use past papers to practise applying knowledge and identifying areas that need more work.

Turn mistakes into a revision list

Keep a short record of questions you get wrong or concepts you cannot explain clearly. Group similar mistakes together.

For example, you may discover that you understand a formula but struggle to identify when to use it. Another student may remember definitions but find application questions difficult. Your revision plan should respond to your actual mistakes.

Break large topics into smaller sessions

Trying to finish an entire course in one sitting can make revision feel overwhelming. Divide large topics into smaller sections.

For a science course, you might separate definitions, processes, calculations and application questions. For a humanities course, you could divide a broad topic into key arguments, evidence, concepts and likely essay questions.

Shorter focused sessions can also make it easier to return to difficult material later.

Use your lecture notes properly

Your lecture notes should be a starting point for revision, not the only material you use. Compare them with the course outline and prescribed resources so you can see which areas need further study.

If your notes are incomplete, fill the gaps from reliable course materials rather than guessing what the lecturer meant. Our guide on how to take lecture notes at university explains ways to organise notes so they are easier to review later.

Use spaced revision

Instead of studying a topic once and abandoning it, return to it at later sessions. Spaced practice gives you repeated opportunities to retrieve information after some time has passed.

For example, you could review a difficult topic on Monday, test yourself again on Wednesday and revisit it during a weekend practice session. The exact schedule can change according to your exam dates and workload.

Study with other students when it helps

A study group can be useful when members prepare before meeting. You can compare explanations, quiz one another and discuss difficult questions.

Keep the group focused. If a session becomes mostly conversation without meaningful study, return to a clear task such as solving questions or explaining concepts to one another.

Know when to study alone

Some tasks are better completed independently. If you need to concentrate on a difficult reading, memorise terminology or work through calculations, a quiet individual session may be more productive.

You do not have to choose between studying alone and studying with others. Use each approach for the type of work it suits.

Protect your sleep before exams

Staying awake all night may give you more hours with your books, but it can leave you tired when you need to concentrate and recall information.

Try to keep a consistent sleep routine as your exams approach. Plan your revision so that you are not regularly relying on overnight study sessions.

Eat, drink and take breaks

Exam preparation works better when basic needs are not ignored. Keep water available, eat regular meals and take short breaks during longer study sessions.

A break does not need to become an hour of scrolling. Stand up, walk around, stretch or step away from the study space before returning to your work.

Reduce distractions

Choose a study environment where you can concentrate. Put your phone away or use a setting that limits notifications during a study block if that helps you stay focused.

If you study online, keep only the tabs and resources you need for the current task. Social media and unrelated videos can quickly turn a short break into a long interruption.

Prepare for different types of exam questions

Your revision should match the type of assessment.

Multiple-choice questions

Practise distinguishing between similar options and explaining why an answer is correct. Do not rely only on recognising a familiar phrase.

Short-answer questions

Practise giving a direct answer with the important facts or steps. Check whether your response actually addresses the question.

Essay questions

Practise planning an argument, selecting relevant evidence and organising your answer clearly. If time is limited in the exam, practise writing within a realistic time period.

Calculation or problem-solving questions

Work through problems without immediately looking at the solution. Show your steps and identify where an error occurred when your final answer is wrong.

Plan the day before the exam

The day before an exam should not be your first serious revision day. Use it to review key areas, practise a few questions and check anything you still need to prepare.

Confirm the exam time, location and any required materials. If your university provides examination instructions, read them rather than relying on what another student says.

What to do on exam day

Give yourself enough time to reach the examination venue. Carry the identification, stationery or other permitted materials required by your institution.

Before the exam begins, avoid trying to learn a large new topic in a panic. A brief review of key points can be useful, but last-minute cramming should not replace the preparation you have already done.

Use a simple weekly revision routine

If your exams are still several weeks away, you can build revision into your normal study timetable. For example:

• After each lecture: review the main ideas while they are still familiar.
• During the week: test yourself on older topics.
• At the weekend: practise questions and review mistakes.
• Before the exam: increase practice on weaker topics.

This approach spreads revision across the semester instead of making the final week carry the entire workload. You can adapt it to your course and timetable.

Common exam preparation mistakes

• Waiting until the night before to start revision
• Rereading everything without testing yourself
• Spending equal time on topics you already understand and topics you find difficult
• Ignoring past questions when useful ones are available
• Studying for long periods without meaningful breaks
• Copying answers without understanding the method
• Staying awake all night repeatedly
• Relying on leaked or unauthorised examination materials
• Ignoring official examination instructions

Frequently asked questions

How many hours should I study for an exam?

There is no useful number of hours that applies to every student or course. Focus on the quality of your study, the amount of material you need to cover and the time available before the exam.

Is it better to study at night or in the morning?

The best time depends on when you can concentrate consistently. Choose study periods that fit your timetable and protect your sleep.

Should I study every subject every day?

Not necessarily. Rotate subjects according to your exam dates, difficulty and current level of preparation. Make sure important subjects receive repeated attention over time.

Are past questions enough to prepare for an exam?

No. Past questions can be useful practice, but they should be combined with your course material, lecture notes and other resources required for the course.

What should I do if I am far behind?

Start by listing the topics and identifying the most important gaps. Focus on understanding core material first, then practise questions and return to weaker areas. If you are unsure about course requirements, ask your lecturer or department for guidance.

Final advice

Good exam preparation is less about studying continuously and more about using your time deliberately. Start early, test yourself, practise applying what you know and return to difficult topics more than once.

Build your revision around your actual courses and exam dates. Keep your study timetable realistic, use your lecture notes as a foundation and make time for sleep and breaks. With a consistent routine, you can prepare thoroughly without depending on last-minute cramming.
