Don’t know what year you went through, but it was still out on the point when I was there.
The girls I trained always passed, every last one of them, first time out. Men too for that matter. Why? I took them out at 5 and ran the seawall, hit the bridge, joined the course half way through, circled the point, and then did the first half on the way back.
Learning to do the obstacles tired and steady made them easy come test time. Everyone did the men’s course by the way, and my girls would literally laugh at the others who couldn’t handle such an easy course.
I graduated in 1981.
The O-course was not hard, but a large number of women had difficulty. Additionally, the course was timed and scored differently for men and women.
