The Individual Volley Ball Efficiency application is dedicated to observing individual Volley Ball efficiency by students.

The application is intended for a "referee" or "coach" located at the level of the posts to observe on the top line, a player on the left (like Left) and the bottom line, another player on the right (like Right) .

Optionally, you can use the top line for the high keys and the bottom line for the headlines.

The score is read in the direction of reading in Thousands - Hundreds - Tens - Units in order to be able to quickly recover the score. Also, there is the possibility of visualizing the percentage of success in each level in order to help students become aware of their current levels of practice.
