My swim test is today... I have to do a 200 ft. freestyle swim, a 100 ft. underwater swim (length of the tank), and a free-dive to the bottom of a 26 ft. tank, retrieve a 50 pound weight and swim back up. Then hop out of the tank, run up a hill carrying two water buckets and back down, only to finish with having to speak into a mic without being breathy. :leaving: Wish me luck!
