The choice between revising using flowcharts or focusing on solving numerical problems for Commerce will depend on your individual learning style and the specific topics you need to revise.

Flowcharts can be a helpful tool for visually organizing and understanding complex concepts, especially in subjects that involve processes, decision-making, or systems. They allow you to see the connections and relationships between different components, which can aid in comprehension and retention. If you find that you learn well through visual representation and need a comprehensive understanding of the concepts in Commerce, revising using flowcharts may be beneficial.

On the other hand, Commerce often involves numerical calculations, financial analysis, and problem-solving. If you have a good grasp of the underlying concepts and theories, practicing solving numerical problems can help reinforce your understanding and improve your ability to apply those concepts in real-life scenarios. This approach can be particularly useful if you struggle with the quantitative aspects of Commerce or need to improve your problem-solving skills.

Ideally, it would be helpful to incorporate both flowcharts and numerical problem-solving into your revision strategy. Start by creating flowcharts to visualize the concepts and processes, ensuring you have a solid understanding of the content. Then, practice solving numerical problems that relate to those concepts to reinforce your understanding and build your skills.

Ultimately, the most effective approach will depend on your personal learning style, the specific topics you need to revise, and your overall goals for Commerce. It may be helpful to experiment with both methods and see which one works best for you.
