Man, I'd love to qualify in that agency. The world record is only 3 mins 40. Clearly I'm not pushing my students hard enough!
To my point, there arn't any "time limits" on the swimming tests other than what would be considered "normal" for the students. Todays standards allow the average person to obtain a scuba certification without any "training" for swimming.
I didn't meant to apply that todays classes some with their own "swim coach" to beat you in to shape to swim on the Olympic team
