Here are some strategies that can help improve memory retention for commerce:

1. Create a study schedule: Allocate specific time each day to study commerce and stick to the schedule. Consistency and regularity are key to improving memory retention.

2. Break down the information: Instead of trying to memorize everything at once, break down the commerce topics into smaller, manageable chunks. Focus on understanding the concepts and then move on to memorizing the details.

3. Use mnemonic devices: Mnemonic devices are memory aids that help in remembering information. Create acronyms, visual imagery, or rhymes to associate with the commerce concepts, formulas, or key terms.

4. Teach someone else: Teaching someone else is an effective way to reinforce your own understanding and memory retention. Explain commerce concepts to a friend or family member, or even write a blog or create a YouTube video explaining the topics.

5. Use visual aids: Visual aids, such as diagrams, charts, or mind maps, can help you visualize and remember complex commerce concepts. Create your own visual representations or use online resources for visual learning.

6. Practice active recall: Instead of passively reading or reviewing notes, engage in active recall by testing yourself on the commerce topics. Use flashcards, practice quizzes, or create your own questions to test your memory.

7. Make connections: Find connections between different commerce topics or relate them to real-life examples. Making associations and connections helps in better understanding and memory retention.

8. Take breaks and get enough sleep: Studying for long periods without breaks can hinder memory retention. Take short breaks every hour or so to rest your mind. Additionally, ensure you get enough sleep as sleep plays a crucial role in memory consolidation.

9. Use multiple senses: Engage multiple senses while studying commerce. Read aloud, write notes, or create audio recordings of the commerce topics. The more senses you involve, the better your memory retention will be.

10. Stay organized: Keep your study materials, notes, and resources organized. A clutter-free study area and well-organized notes can help in better recall and memory retention.

Remember, improving memory retention takes time and practice. Be patient and consistent with your efforts, and you will see progress over time.
