tracking your card This will help you work on the weakest part of your game to see where you are losing most shots in a round of golf, so that you can see your strengths, weakness and what you should improve on.
Its always good to make notes of your score after you play a round of golf if you want to improve your game. You take notes of how many times where you were on the left side of the tee or how many times you were on the right side of the tee over 18 holes so you can improve on that area. Make notes if your approach shots were short off the green, and how many putts you left short of the flag. This will help you become more aware of where you need to improve your game.
