Sometimes i forget the score of the Game. usually first 2 point are okay but after a long rally , i have no idea if I serve on the deuce side or ad side. usually in the beginning of the game, like 15-15 or 30-L or L-30 I can remember. But starting at 30-15 or 15-30 or 30-30 i start to lose concentration on the score when we get to 40-40 then i can remember. ad in and ad out. but the middle phases of the game I sometimes forget especially if its a long point. How do you stay focus and keep score in your mind the middle of the game?
