that's okay. I am going to give myself some rest for now and perhaps come back stronger. I have been through much fatigue. I know my limit and I as a person wanting to join certainly can't compete with people who's been running all their life in the Legion where their bodies were so well conditioned during that 10+ years. but still all your feedbacks are appreciated and received with gratitude. At least knowing something is better than knowing nothing. I can already foresee the out-come as I would probably be one of the slowest guy on the test. I can only improve upon what I already had and push it during the selection.
Go take swims, in between (yes, you will be put on trial even in this domain, if you do get accepted Swim or sink in 3 minutes!), best cure. Don't push yourself, 'being the slowest guy', you will only find out once there.
I should add, the distance to swim is 100 meters surface (breaststroke, crawl or whatever makes you float) and to finish, with out stopping, dive and + 10 meters underwater, all this maximum time 3 minutes.
