What is the easiest way to copy and past recently entered data in sheet 3?

Hello All,

I have a master sheet, where I update new extra data and copy recently entered data to new worksheet "Sheet3" for mail merge. I am using simply copy and paste command. Is it any other way to copy and paste recently entered data to sheet 3? Your suggestion is highly appreciated. |Sample file is also attached herewith. Thank you.
