I'm in the military and had to leave for two weeks so I missed 4 days of golf. On my behalf, I notified all my teachers except my golf instructor. I thought he wouldn't even notice since he doesn't take attendance; he was on vacation for a month and half. Anyhow, he failed me in his class. I talked to him and told him I would give him a letter from the Air Force but he said it wouldn't matter and my grade stands.. Is this going to look bad on my application?
