Swimming
I officially hate swimming tests. I had to take one for this scuba diving class I wanted to take. It was so bogus. We had to swim a lap without breathing. I couldn't do it. I passed everything else. I can swim 350m in exactly 9min, tread water for 10min, get a 10lb weight belt from the bottom of a 7ft pool. The second two were really easy. The first one was painful. So now I'm at the bottom of the waiting list so I probably won't get in.
