In the shool, in a work, i had a 14/20, and my parents are very hungry, and i can't use the computer in all the shool day: monday to friday.
But the saturday and the sunday i can use the computer. I have to win a 17/20, 18/20, 19/20 or a 20/20 to play all the days.
I hope you understand my english, i'm bad.
