Waterpolo and Chemistry

One of my main passions is waterpolo. It is a great physical sport. I play Mills Varsity Waterpolo. As of now, I play goalie for my team because we only have 7 eligible players to play. The rest of the players will be eligible by next thursday. We have not won one game yet and hopefully we will win tomorow against Carlmont. One thing about waterpolo that really bugs me is that every tuesday and thursday I have to leave school for my games. This causes me to miss out on chemistry class. I am now really falling behind in chemistry and i feel I have less of an understanding than the rest of the class.
