Guys ive been to the qualifications but i dont get it

what is in on ur screen the scores?

u got a "right and left" number.
the rechts is KO above. so i think thats the numbers u killed
and the other one is the times u died?

and kill - died = score?

and that are the same scores as the windows shows from the other players?

The number on the right is how many kills you made (so is your score). Someone please correct me if I am wrong but I believe the number on the left hand side is how many people are currently alive in the round, the number constantly changes because people are always respawning.

Deaths does not matter when it comes to determining your score, only kills do.
