This Golf Tier System (GTS) Flash Cards are 'medium' and are perfect for GTS Rating 2.0 or a 2.5 players, who probably score between 105 and 90. This player has had experience on the course and know about safety and etiquette. The Medium Flash Cards help players identify definitions and rules and there are 60 cards in the set. The two Ruby and Pals characters are Stella (10 years old from NYC) and Peter (10 years old from London, England). Peter would love to be a referee when he grows up, actually Peter is obsessed by the rules and would like to be on the cover of the hardest set of Flash cards... Stella loves fashion and hair.
