GPA in numbers, ie, 3.1. A list of all your classes would be nice from 9th-12th grades. In water polo most coaches want good students or students that they know can make it through the University. Size and weight are important. Just like basketball and football size and weight have become more and more important in water polo.
Swimming times are important.
The game is played in the water and speed in the water is a very objective measure and very important to success. The level of competition varies greatly from area to area and league to league so being all league or even Al l American is pretty subjective but swimming times are very objective. Again these are objective measures. I am not really interested in video tapes of you playing because I don't know who you are playing against and what the level of competition is. These are the things I believe coaches want to know, at least these are the things I want to know.
