The best way for an amateur to improve their game/course management is to use technology such as Decade Golf or Swing U Premium GPS. These are app or web based systems that can track your shots and how you play the course. You will get strokes gained data and learn more about strengths and weaknesses. You will understand how far your clubs go on the course. All of these stats and metrics will help you understand how to practice better and play smarter!
