How to Revise in the Last 30 Days Before Your Exam

Thirty days sounds like a lot until you realise how many topics you have not touched. Some students panic, try to read everything again and end up retaining nothing. A better approach is to treat the last month like a training camp: you already have the ingredients, and now you sharpen what matters most.

This plan assumes you are writing a major exam such as JAMB, WAEC or NECO and have some knowledge of your subjects already. Adapt it if your exam dates differ, and check the official timetable on the exam body's website for your own dates.

Principles for the last 30 days

1. Prioritise. Not every topic is equally likely or equally weak. Spend most time on high-frequency topics where you lose marks.
2. Practise more than you read. Doing questions and fixing errors beats rereading.
3. Space it out. Revisit each subject several times a week. See how to study effectively.
4. Protect your health. Sleep, food and short breaks are part of revision. Read healthy habits during exams.
5. Stay flexible. Plans bend. Keep a catch-up slot.

Before day 1: a quick audit (one evening)

1. List every subject and its main topics from the syllabus.
2. Rate each topic: Strong, Medium, Weak. If you are unsure, do five questions on it.
3. Mark topics that appear often in past questions. How to use past questions explains how to spot patterns.
4. Decide your daily study hours using your real schedule (school, lesson, chores, light). A plan you can keep is better than a perfect one you cannot.

Write a one-page list: Top 10 weak topics across all subjects. These will get most of your attention in weeks 1 and 2.

Week 1 (Days 1 to 7): Repair

Goal: fix the biggest gaps.

• Spend 60% of study time on weak topics, 40% on medium topics.
• For each weak topic: read concise notes, solve worked examples, then do 10 questions.
• Start your mistake log.
• Do one timed mixed set at the end of the week to measure progress.

Sample day (3 hours, about 2 subjects):

Week 2 (Days 8 to 14): Strengthen

Goal: turn medium topics into strong ones and keep weak topics alive.

• Rotate through all subjects at least twice.
• Add mixed practice: 20 to 30 questions from different topics in one sitting.
• Revisit week 1 topics for 15 minutes each (spaced review).
• Make one-page summaries of formulas, definitions and key facts for each subject. These become your final revision sheets.

At the end of week 2, do a timed section in your hardest subject, then review in detail.

Week 3 (Days 15 to 21): Simulate

Goal: build exam stamina and pacing.

• Take full or half mock papers in exam conditions: no phone, no notes, strict timing. For a computer-based exam, practise on a screen. See CBT exam tips.
• After each mock, spend as long reviewing as you spent writing it. Update the mistake log and classify errors: knowledge gap, misread, careless, time.
• Revisit your weakest 5 topics again.
• Practise time plans: how many minutes per question, when to skip.

Schedule mocks at the time of day your exam is likely to take place so your body gets used to it.

Week 4 (Days 22 to 28): Sharpen

Goal: consolidate and calm.

• Do shorter, targeted practice on remaining weak spots.
• Re-read your one-page summaries daily. Say formulas and definitions aloud.
• Do one lighter mock every two days.
• Go through your mistake log from the start. Re-test yourself on past errors.
• Stop learning big new topics around day 25, unless they are very high-frequency and you have time.

Days 29 and 30: Rest and prepare

• Day 29: Light review of summary sheets, 90 minutes at most. Prepare your bag and documents using the exam day checklist. Do something relaxing.
• Day 30: Short review in the morning, an early dinner, and sleep. Do not stay up all night.

If your exam spans several papers, plan a light review for each night before the paper, not a full study session.

A daily rhythm that works

Adjust to your reality. If you have no light in the evening, move paper tasks earlier or use a rechargeable lamp. If data is limited, download your practice sets beforehand. Boarding students can use prep time for the main block and lights-out for silent recall.

How to split time across subjects

If you are writing four or more subjects, weigh them like this:

Do not drop a strong subject completely; one session per week keeps it fresh.

What to cut when time is short

If you are behind schedule:

• Skip decorative note-making (colouring, copying).
• Drop topics that appear rarely and are hard for you, unless you have time.
• Cut social media and long chats during study blocks.
• Move from reading to questions sooner.

Do not cut sleep. A tired mind forgets more than it learns.

Using the last 30 days with a group

A study group can help in weeks 2 and 3: quiz each other, explain topics and mark mocks. Keep sessions short and structured; see group study tips. Avoid groups that spread rumours about leaked papers; trust your preparation.

Common mistakes

Tracking progress

Keep a simple chart: for each mock, note your score and the main reason for lost marks. A rising line, even slowly, shows the plan is working. If the score is flat, look at the mistake log and change your focus.

Final word

Thirty days is long enough to make a real difference if you stay focused and honest about your weak points. Start with the audit tonight, set up your mistake log and book your first timed set. You can begin a timed practice session on ExamPadi with 46,182 questions across JAMB, WAEC, NECO and NABTEB, free to start on Android, iOS, web and Windows.
