My experience in high school was identical to yours. All the PE classes were pseudo team sports where I prayed never to be picked to play and rarely was. In the testing, I failed everything except the 600 yard run/walk. The reason I passed that? I walked the mile-one-way to and from school every day. And ran it when running late in the morning or needing to get home in a hurry in the afternoon. I was in shape for that test because I was conditioned.
