I know this might sound like a crazy question
But I'm working on getting my swim skills back after not having swam for a very long time. I personally find swimming in 5ft water different from 9ft different from 12ft yada yada yada.
How deep is the pool the swim test is held? Or does it gradiate from 3ft-5ft-8ft etc?
Is one "lane" down the pool length-wise 100m or is it back-forth, around the edges?
Also, how do they define treading water? I can tread water easily in a semi-doggy paddle but is that too much forward movement?
Thanks so much for your help
