The Feynman method: the ultimate technique to truly understand your courses

Introduction

You may spend hours reviewing your course without being able to remember. That's normal: simple rereading is not enough. Most students learn passively, which explains why they forget quickly.
The Feynman Method proposes the opposite: to understand deeply. It is a simple technique, used by one of the greatest physicists in the world, that helps you learn faster, retain longer, and practice with active memorization.

Discover how this method can transform your revisions.

1. The Feynman Method: What is it exactly?

Invented by Richard Feynman, Nobel Prize winner in physics, this technique is based on a strong idea: if you cannot explain a concept in simple words, it means you have not truly understood it.
This principle has become a reference in smart revision, as it forces your brain to clarify, structure, and reformulate your knowledge.

Science confirms its effectiveness. By explaining a concept, you activate deep understanding, active memorization, and you directly combat the forgetting curve.

2. The 4 steps of the Feynman Method

Step 1: Choose a specific concept

Not a whole chapter. A concept, an idea, a formula, a mechanism, a definition. The clearer it is, the more effective it is.

Step 2: Explain in simple words

Imagine you are talking to a 12-year-old child. No jargon, no vague sentences.
You can write your explanation on a sheet, record yourself, or film yourself.
Hesitations, gaps, and complicated words: these are the signs that you have not understood yet.

Step 3: Identify the unclear areas

Go back to your course to understand the passages where you struggle.
This is the key step. The unclear areas are the places where your brain signals that you have not assimilated the concept.

Step 4: Simplify, structure, narrate

You reformulate even more simply.
You can create a metaphor, a little story, a concrete example.
At the end, you should be able to summarize the concept in a few easy-to-understand lines.

3. Why the Feynman Method works so well

The Feynman Method activates several powerful levers to learn faster.

• Active memorization: you engage your brain instead of passively rereading.
• Immediate verification: you quickly know if you really understand.
• Deep learning: you go beyond rote memorization.
• Long-term retention: by restructuring the information, you retain better.
• Critical thinking: you learn to analyze, simplify, and explain.

This technique is perfect if you want to better understand your courses, retain a difficult chapter, or make progress on a concept that resists you.

4. How to apply the Feynman Method during your revisions

Solo

• Blank sheet
• Explanation out loud
• Diagram or mini summary
• Simple example created by you

In pairs

• Explain a concept to a friend
• Ask each other questions
• Correct each other on the unclear areas

Before an exam

• Create a Feynman micro fiche
• Summarize your chapter in 5 lines
• Practice as if you were teaching the subject

5. Feynman Method applied to different subjects

Example for medicine

Explain a biological reaction as if you were telling a little story.
Simplify a complex mechanism by comparing it to a queue, a journey, a filter.

Example for law

Reformulate a legal principle as if you were telling a situation from everyday life.
Example: a contract, a liability, a simple rule.

Example for math

Transform a formula into a mental image.
Explain why the formula works, not just how to apply it.

Example for literature

Summarize a text as if you were telling it to a friend in five sentences.
Simplify a theme, style, author’s intention.

Example for business

Explain a marketing concept as if you had to present it to a child.
Use a very concrete example to check your understanding.

6. Mistakes to avoid

• Just reread.
• Believe you have understood because you recognize the course.
• Explain with complicated sentences.
• Not write.
• Skip the step of identifying unclear areas.
• Use overly complex metaphors.

The Feynman Method is not magic. It works if you play the game of simplicity and clarity.

7. Integrating the Feynman Method into your schedule

You don’t need to spend 2 hours on it.
• Short format: 5 minutes to explain a concept.
• Long format: one concept per chapter section.
• Daily format: a micro explanation per day.

With repetition, you will develop a more solid understanding and memorize your courses in the long term.

8. How Koro AI helps you use the Feynman Method

You can use Koro AI as support to apply this technique.
The app generates simple sheets from your courses and quizzes to verify if you really understood.
When you make mistakes, it automatically identifies your unclear areas.
The goals, small comments, and gamified progression help you practice the method without realizing it.

It is a complement, not an obligation, but it makes the method even smoother.

Conclusion

The Feynman Method is one of the most effective revision techniques for understanding your courses, retaining longer, and learning faster.
It forces you to reformulate, simplify, and verify your understanding.
It is an accessible, scientific, powerful method, and perfect for making progress, no matter your field.

You can start today by taking a small concept and explaining it on a blank sheet.
The more you use it, the more you will see the difference in your revisions.
