What is the scorecard and certification in Golf?

Section 6: Scoring

The score for each hole is the number of strokes taken plus any penalty strokes; the round score is the total for 18 holes, and the championship score is the total for all rounds played.
Scores are commonly expressed relative to par (for example, "10 under par").

In stroke play, a marker (typically a fellow competitor) keeps the player's score hole by hole.
After the round the player checks the hole-by-hole scores, ensures they are correct, and certifies (signs/attests) the card in the scoring area; the marker also certifies it.
Returning a scorecard with a hole score lower than actually taken, or failing to certify the card, carries penalties under the Rules of Golf — a returned card is the player's responsibility.

The champion is the player with the lowest 72-hole total (or the playoff winner if tied).
Players tied for any other position share that position; prize money for the tied positions is pooled and divided equally.

Finishing position in an official event earns FedExCup points on a published scale, with the winner earning the most.
FedExCup points determine eligibility for the season-ending Playoffs and feed the priority ranking that sets future event access.
Official money and official-event statistics are credited based on the certified results.
