Yes, it is beneficial to revise by teaching the concepts to someone else.

Revising by teaching the concepts to someone else is a highly effective method of learning and retaining information. When you teach someone else, you are actively engaged in the material and have to explain it in a clear and concise manner. This process enhances your understanding of the topic and solidifies your knowledge.

Benefits of revising by teaching:

1. Reinforces understanding: Teaching someone else requires you to break down complex concepts into simpler terms. This process forces you to fully understand the material and identify any gaps in your knowledge. By explaining the concepts to someone else, you reinforce your understanding and fill in any missing pieces.

2. Identifies knowledge gaps: Teaching someone else can highlight areas where you may have misconceptions or gaps in your understanding. When the person you are teaching asks questions or brings up points you haven't considered, it helps you recognize areas that need further clarification or review.

3. Enhances retention: Teaching someone else requires you to recall information from memory, which strengthens your memory and retention of the material. By actively engaging with the content and explaining it to another person, you reinforce the neural pathways associated with that knowledge, making it easier to recall in the future.

4. Improves communication skills: Teaching someone else helps improve your communication skills. It requires you to organize your thoughts, articulate ideas clearly, and adapt your explanations based on the other person's understanding. These skills are transferable and valuable in various personal and professional settings.

5. Boosts confidence: Successfully teaching someone else and seeing them grasp the concepts can boost your confidence and self-esteem. It validates your knowledge and abilities, motivating you to continue learning and revising effectively.

In conclusion, revising by teaching the concepts to someone else is a highly beneficial approach. It reinforces your understanding, identifies knowledge gaps, enhances retention, improves communication skills, and boosts confidence. By actively engaging with the material and explaining it to another person, you solidify your knowledge and increase your chances of retaining the information in the long run.
