Keeping score is really easy wants you learn it.
When you start a match you say 0-0, because no one has won a match.
To win a set depending on the game you are playing like a 8 game pro set the first on to 8 wins, but if you are 7-8 then you have to win by two. But say you go into a tie braker then its a diffrent story.
If you are playing singles and the ball hits in the doubles lane then you would say out or hold up one finger. If the ball is outside the court it is out, and if you hit the ball on the opposite side then it is out. But you get to serve one more time ONLY IF YOU ARE SERVING AND IT IS OUT.
These are the scores when you play.
