Here's what we know:
* The Games are not about scores: The Hunger Games are a televised spectacle of survival. The focus is on individual performances, alliances, and strategic gameplay. There are no clear-cut scores or rankings throughout the competition.
* Survival is the primary goal: The ultimate objective is to be the last one standing.
* Sponsors influence the game: Sponsors play a crucial role in the Games, providing resources and influencing the tributes' performance. While they might have internal metrics, those are not revealed to the audience.
While there's no official training score, we can assume that the tributes are evaluated throughout their preparation for the Games based on their skills, strategic thinking, and overall fitness. However, this is never explicitly quantified in the books or movies.
