Hi there!

You’re absolutely right about the update on your marksheet. If your improvement exam was in 2024 but you want to avoid using the new marksheet because of the date, you can still use your old marksheet for some purposes. However, it's important to ensure that any institution or organization you’re dealing with is aware of the improvement and the current status of your marks. They might require documentation to verify the changes.

If you have any specific places where you're unsure, it might be best to check directly with them to confirm what documentation they'll accept. Let me know if you need any more help!
