At 4am, I realized my card had been miss added. My club is closed on Monday, so I haven't seen my card. I think the correct scores for the individual holes were written down, but then the total for the front nine was 3 higher than it should have been. I don't think I am DQ'd, but what score should be used for the tournament results?

If the correct scores for each hole was entered than there is no penalty. You do not need to know how to add to play golf.

What score is used? It is the difference between 1st and 2nd....

6-6d/2 Total Score Recorded by Competitor Incorrect
Q. In stroke play, a competitor returns his score card to the Committee. The hole-by-hole scores are correct, but the competitor records a total score which is one stroke lower than his actual total score. Is the competitor subject to penalty?

A. No. The competitor is responsible only for the correctness of the score recorded for each hole — Rule 6-6d. The Committee is responsible for the addition of scores — Rule 33-5. If the competitor records a wrong total score, the Committee must correct the error, without penalty to the competitor.
