🚨 Only a few days left? Don’t panic. Here’s how to revise smart and still score well.
We’ve all been there—you look at the calendar and realise exams are just around the corner… and you’re nowhere near done revising. Maybe you started late, maybe life got in the way, or maybe you underestimated how long revision would take.
Whatever the reason, here’s the good news:
🧠 It’s not too late—if you focus on the right things now.
In this guide, we’ll share 7 practical, high-impact tips to help exam prep be effective when time is running out.
✅ 1. Prioritise High-Weight Topics
🎯 When time is short, not all topics are worth the same. Focus on what gives you the most marks.
In last-minute exam prep, trying to study everything is the fastest way to get overwhelmed and anxious. That’s why the smartest move is to prioritise topics based on how heavily they’re weighted in the exam.
Ask yourself:
-
Which topics appear most frequently in past-year papers?
-
Which chapters carry the most marks in structured questions or essays?
-
Which weak topics are still mark-heavy and worth revising?
For example:
-
In O-Level E-Math, topics like Algebra, Graphs, and Geometry often make up a large percentage of Paper 1 and Paper 2.
-
In Biology, you’ll often see high-weight chapters like Photosynthesis, Respiration, and Reproduction tested year after year.
💡 You don’t need to know everything—you need to master the chapters that make up 70–80% of the exam.
🔍 How to Identify High-Yield Topics for Exam Prep:
-
Look at past 3–5 years of exam papers and tally the topics that appear most
-
Use school-provided revision summaries (they usually highlight key topics)
-
Ask your tutor or teacher, “Which chapters tend to be tested the most heavily?”
-
Highlight topics you’re still unsure of but know are high-weight
📌 Focus First, Then Fill in Gaps
Start with:
-
Core foundational topics
-
Topics you frequently lose marks in
-
Anything that’s appeared multiple times in recent papers
Then, if you have extra time, brush up on:
-
Lighter, niche topics
-
Bonus content (that may not appear at all)
📈 Spending 2 hours on a topic that appears in 20-mark questions is way smarter than spending 2 hours on a topic that rarely shows up.
✅ 2. Do Active Recall, Not Passive Reading During Exam Prep
📚 When time is short, don’t just review—retrieve.
Reading your textbook or highlighting notes might feel productive, but research shows that passive revision methods (like rereading or underlining) have very low memory retention—especially under exam stress.
When you’re in last-minute mode, you need every minute of revision to count. That’s where active recall comes in.
🧠 Active recall is the process of trying to retrieve information from memory—without looking at your notes first.
🔍 Why Active Recall Works:
-
It strengthens memory and helps your brain rebuild the “path” to the answer
-
It mimics exam conditions—retrieving info without prompts
-
It helps identify what you actually don’t know yet, so you can fix it fast
-
It works even if you only have a few days left
In fact, one study from cognitive psychology found that testing yourself is more effective than rereading, even if it’s just once.
🛠️ How to Use Active Recall in Crunch Time for Exam Prep:
-
Cover and test: Read a section of notes, then cover it and write or say what you remember
-
Use flashcards: Physical cards or apps like Anki or Quizlet are great for quick-fire revision
-
Teach someone else: Explain a concept to a sibling, friend, or even your pillow. If you can teach it clearly, you’ve mastered it
-
Try mini “closed-book quizzes”: Create short 5-question mini-tests from your notes or textbook headings
✅ If you’re staring at notes but can’t reproduce them from memory, it’s time to switch to active recall.
🧪 Active Recall vs Passive Review:
Method | Effectiveness (Especially for Exams) |
---|---|
Rereading notes | ❌ Low – creates false confidence |
Highlighting | ❌ Low – visually pleasing but ineffective |
Watching videos | ⚠️ Medium – good for first-time learning only |
Active recall (quizzing, teaching, flashcards) | ✅ High – strengthens memory under pressure |
✅ 3. Focus on Past-Year and Commonly Tested Questions
📄 If you only have time for one type of practice, make it this.
When time is running out, the smartest move is to practise the kind of questions you’re most likely to see on exam day. That means going straight to:
-
Past-year papers
-
Commonly tested questions
-
Ten-Year Series (TYS) or school mock exams
These aren’t just “practice” questions—they are real-world previews of your actual exam. They show you how questions are asked, what the markers want, and what patterns keep repeating.
🧠 This isn’t guesswork—it’s exam-smart preparation.
🔍 Why Past-Year Questions Work:
-
They help you spot question trends
(e.g. “Electricity always comes out as a long question in Paper 2.”) -
They teach you how to apply concepts, not just remember them
-
They train your timing and stamina for the actual paper
-
You learn how answers are marked and what key phrases are expected
You’re no longer just studying—you’re rehearsing for the real test.
📘 How to Use Past-Year Questions Effectively (Even Last-Minute Exam Prep):
-
Sort questions by topic, not by year
→ Focus on your weaker areas first -
Attempt questions under timed conditions
→ Helps improve speed and pressure-handling -
Check with official marking schemes
→ Learn how to phrase your answers the way examiners want -
Highlight “repeat-style” questions
→ Spot patterns across 3–5 years of papers -
Redo questions you got wrong
→ Don’t just move on—learn from your mistakes
🧠 What to Focus On during Exam Prep:
Subject | High-Yield Question Practice |
---|---|
Math | Full-paper TYS drills + problem-solving word problems |
Science | Application-based structured questions + definitions |
English | Summary & comprehension strategies from past papers |
Humanities | Essay planning + source-based questions from past years |
🎯 You don’t need to do 10 full papers—just focus on the questions that repeat most.
✅ 4. Review Your Mistakes Log (If You Have One)
❌ Your biggest exam gains come from fixing your past mistakes—not rereading what you already know.
When you’re short on time, the most efficient way to revise isn’t to cover every topic from scratch—it’s to target your weak spots directly. And the fastest way to find those weak spots? Your mistakes log.
A mistakes log is a personal record of:
-
Questions you got wrong in school tests or mock exams
-
Concepts you consistently forget or misunderstand
-
Topics where you lose marks due to carelessness or confusion
📘 If you’ve been tracking your mistakes, now’s the time to go through them—and clean them up once and for all.
🔍 Why Reviewing Mistakes Is So Powerful:
-
It helps you avoid repeating the same errors
-
You get faster score improvement by fixing what’s holding you back
-
It builds exam confidence, since you’ve already faced and corrected your past weak points
-
You turn mistakes into learning opportunities instead of letting them pile up
🧠 Your exam paper won’t test everything—it will definitely test areas where most students trip up. So fix those areas first.
🚀 Don’t Have a Mistakes Log? No Problem.
You can still do this last-minute:
-
Go through your latest school tests, worksheets, or tuition practices
-
Highlight all incorrect questions
-
Ask yourself:
-
Was it a conceptual mistake?
-
A careless mistake?
-
A time management issue?
-
-
Re-attempt those questions without looking at the answer key
-
If you still don’t get it—review the concept and redo a similar question immediately
This quick exercise turns every wrong answer into a chance to earn marks back on the real exam.
🧠 Pro Tip: Categorise Your Mistakes
Type of Mistake | Example | Fix |
---|---|---|
Conceptual | Forgot why current is same in series circuit | Review the concept with visuals or notes |
Application | Misread the graph in Bio | Practise more data-response questions |
Careless | Skipped a step in algebra | Slow down & double-check workings |
Time-related | Ran out of time for last section | Use Pomodoro or timed practices to build speed |
✅ Fixing one repeated mistake could be worth 3–5 extra marks in the real paper.
✅ 5. Use Time Blocks to Maximise Focus (Pomodoro Works!)
⏱️ When you’re running out of time, every minute needs to count—and that means cutting out distractions and building momentum.
Last-minute studying often feels chaotic: jumping between topics, checking your phone, or feeling guilty for not doing “enough.” That’s why structured time blocks are so powerful. They give you clarity, focus, and a plan.
The most popular and student-friendly time-blocking method? The Pomodoro Technique.
🍅 What Is the Pomodoro Technique?
-
Study for 25 minutes (one Pomodoro)
-
Take a 5-minute break
-
Repeat 4 times, then take a longer 15–30 minute break
This method helps you:
-
Stay laser-focused during your study window
-
Prevent burnout with built-in rest
-
Measure progress in clear blocks (“I did 6 Pomodoros today!”)
🎯 In exam crunch time, it’s not about studying longer—it’s about studying smarter.
✅ Why It Works So Well During Exam Prep:
Problem | Pomodoro Solution |
---|---|
Easily distracted | 25-minute sprints are short enough to stay locked in |
Feel overwhelmed | Breaking tasks into Pomodoros makes them manageable |
Burn out quickly | Regular breaks refresh your brain and help retention |
No sense of progress | Tracking Pomodoros shows you’re actually moving forward |
🛠️ How to Use Time Blocks for Last-Minute Studying:
-
Set a clear goal per block:
-
Pomodoro 1: “Do MCQ for Chapter 3”
-
Pomodoro 2: “Revise photosynthesis key points”
-
Pomodoro 3: “Do one full Math structured question”
-
-
Avoid multitasking:
Turn off notifications, put your phone in another room, and use a timer app (like Pomofocus.io or Forest). -
Use breaks wisely:
-
Stretch
-
Rehydrate
-
Look away from screens
Avoid opening TikTok/YouTube—it’s too hard to stop at 5 minutes!
-
🧠 Bonus Tip: Stack Pomodoros by Subject
-
2 Pomodoros for Math
-
2 for Chemistry
-
1 for SS Source-Based
-
1 for English summary practice
Rotate subjects to avoid mental fatigue and revise more effectively across the board.
✅ 6. Don’t Skip Sleep – It’s Brain Fuel
😴 Cramming all night sounds productive—until you realise your brain shuts down when it’s exhausted.
When you’re behind on revision, it’s tempting to sacrifice sleep for more study time. But in reality, staying up late and pulling all-nighters can do more harm than good.
🧠 Sleep isn’t just rest—it’s a core part of learning and memory.
Research consistently shows that students who sleep retain more, focus better, and perform with clearer thinking than those who cram through the night.
🔍 Why Sleep Is Crucial During Exam Prep:
-
Memory consolidation happens during sleep
– Your brain actually processes and “saves” what you studied while you sleep. -
Lack of sleep reduces focus and problem-solving
– A tired brain makes more mistakes, forgets formulas, and blanks under pressure. -
Sleep affects mood and stress control
– Without rest, your anxiety levels spike, making it harder to stay calm during the exam.
💡 Even 1 hour less sleep per night for a week can have the same effect as skipping an entire night’s sleep.
✅ How to Sleep Smart During Last-Minute Exam Prep:
Situation | Smart Sleep Strategy |
---|---|
Only 2 days left | Sleep 6–7 hours, wake early to revise with a fresh mind |
Cramming past midnight | Stop at a set time (e.g. 12 AM), review in the morning |
Feeling anxious | Do a brain dump before bed to clear your mind and reduce overthinking |
Trouble falling asleep | Avoid screens 30–60 minutes before bed, dim your lights, and do slow breathing |
💤 Better Alternatives to All-Nighters:
-
Use the Pomodoro method to boost efficiency during the day
-
Prioritise active recall and past-year questions (highest ROI for limited time)
-
Wake up earlier, not later—your brain is sharper in the morning
-
Create a simple 3-hour focused plan instead of aimless all-night review
✅ It’s better to revise 3 hours well and sleep 7 hours, than revise 6 hours poorly and sleep 2.
✅ 7. Have an Exam-Day Strategy Ready
📝 Preparation doesn’t stop when revision ends—how you manage the exam itself can make or break your final score.
Many students spend hours studying, only to underperform on the actual exam because of poor time management, stress, or panic. Having a clear, simple game plan for exam day helps you stay calm, confident, and in control—especially when the clock is ticking.
💡 Knowing your content is half the battle. Knowing how to handle the paper is the other half.
🧠 Why Exam Strategy Matters:
-
Keeps your mind focused under pressure
-
Prevents rushing, blanking out, or getting stuck on hard questions
-
Maximises your ability to show what you know
-
Reduces anxiety by giving you a plan to fall back on
✅ What a Solid Exam Strategy Includes:
⏳ 1. Time Management Plan
-
Break down how much time you’ll spend per section or question
-
For example:
-
MCQ: 20 minutes
-
Short-answer: 30 minutes
-
Essay or structured response: 1 hour
-
-
Stick to your timings—don’t over-invest in one question and sacrifice others
➡️ 2. Skip and Return Rule
-
If you’re stuck for more than 1–2 minutes, move on
-
Come back to difficult questions at the end
-
This ensures you don’t leave easy marks on the table
✍️ 3. Answer Structure Strategy
-
Know the format examiners want (especially for science, essays, and source-based questions)
-
Use key terms, paragraph structure, labelled diagrams where needed
-
Marking schemes are predictable—play to them
📦 4. Pre-Exam Checklist
Prepare your:
-
Stationery (pens, pencils, calculator, ruler, eraser)
-
Entry documents (ID, exam slip)
-
Water bottle
-
Watch (for time tracking if no clock is visible)
Also: know the exam venue and reach early to avoid unnecessary stress.
🎓 Final Thought:
When time is running out, studying smart matters more than studying everything.
Focus on what gives you the highest return: important topics, exam-style practice, and your known weak spots. Rest your brain. Stick to a plan. And walk into the exam knowing you did what matters most.
