When exams are coming, many students try to cram – working for hours without stopping, usually the night before. It feels productive, but it does not work well.

Why Cramming Does Not Work

Cramming puts lots of facts into your short-term memory, but most of it is forgotten quickly. Studies show that after 24 hours, people remember only about 50% of what they crammed.

It’s like trying to run a marathon without training. You might start fast, but you will get tired and stop before you reach the finish line.

The Better Way: Small Chunks and Breaks

Instead of cramming, it is better to revise in small chunks over time with regular breaks. This helps your brain remember things better and keeps you calm.

Benefits of chunking:

• Better memory: Reviewing notes a few times helps move information into long-term memory.
• Less stress: Short sessions feel easier and stop you from panicking.
• More energy: Your brain can rest and focus again after breaks.

Think of it like marathon training. Runners build stamina gradually. They do small runs, rest, and slowly get stronger. Revision works the same way.

Smart Revision Tips

1. Use 20–25 minute sessions with 5-minute breaks. This is called the Pomodoro technique.
2. Mix subjects: Do not spend all day on one topic. Switching keeps your brain active.
3. Test yourself: Flashcards or past papers help more than just reading notes.
4. Plan ahead: Spread revision over weeks, not just days. Students who revise in chunks can remember up to 30% more than crammers.
5. Look after yourself: Sleep, eat well and move your body. A healthy brain learns better.

Conclusion

So, which is better: cramming or chunking? The answer is clear. Cramming may feel fast, but it only helps short-term memory and causes stress. Chunked revision, with small sessions and regular breaks, helps you remember more, stay calm and perform better. Just like a marathon, success in exams comes from steady training, not a last-minute sprint.

The next time you start revising, ask yourself: do I want a short burst that fades, or a consistent effort that lasts? The choice is yours, but the evidence is on the side of chunking.
