Leaderboard types in contests
Participants can see the table of current results during the contest. The results are arranged by the current position of the teams according to the tournament rules. The leaderboard type determines the rules for arranging results.
This page shows typical scenarios for different leaderboards. You can change the leaderboard settings for each tournament.

SCORING |
Participants are ranked by the sum of the points they earned for the problems they solved. Participants with an equal number of points share a position. |
It consists of the points awarded for each test successfully passed by the solution. All tests are equal, and the number of points for a test is fixed in the contest settings. |
It is calculated using the number of points scored for each problem where their last solution was accepted for review. |

ACM |
Participants are ranked by the number of problems solved: the more problems solved, the higher their position. Participants who solved the same number of problems are ranked by the total solution time (the shorter the time, the higher their position). |
It depends on the solution time and the number of unsuccessful attempts submitted before the correct solution: for each attempt with a verdict other than OK/CE, an extra 20 minutes is added to the total time. |
It depends on the number of problems solved and the time taken to solve them. The total solution time is shown in the Penalty column. |
Each participant's solved problems, number of unsuccessful attempts for each problem (if any), number of solved problems, and total solution time are shown. Some time before the end of the contest (usually after 80% of the tournament time), the table freezes: participants see its status as of the time it was frozen rather than the current results. Each team still receives checking system verdicts. The leaderboard freeze and unfreeze times are indicated in the contest settings. |

IOI |
Participants are ranked by the sum of their points for the problems. Participants with an equal number of points share a position. |
It consists of the points awarded for each test successfully passed by the solution. All tests are equal, and the number of points for a test is fixed in the contest settings. |
It consists of the number of points scored for each problem where their last solution was "accepted for review". |
Point values must be integers. |

SHAD |
Participants are ranked by the sum of their points for the problems. Participants with an equal number of points share an equal position. |
Unsuccessful attempts to solve a problem add penalty points for the problem. The final problem score is calculated by deducting penalty points from the problem score. |
It consists of the number of points for each problem, penalty points included. |
The administrator assigns points per problem in the contest settings. |
