Isn't it that you have to pass the pre-requisites prior to diving which is 200 meters/yards ( no time limit ) and a 10 minute float/tread in water? I passed the 200 meters/yards swim but failed the 10 minute tread/float. However, my DI still let me continue attending the PADI OW course ( 3 week course twice a week ). I passed all the confined diving skills and tests, but before our finals, my DI made a condition that I have to pass the 10 minute tread before I can join the 2 final dives in the lake. I have worked hard everyday in the pool for 3 weeks but still failed the 10 minute float/tread and I did not get certified. My question is, why did they still make me go through the whole course if I failed the pre-requisites such as the 10 minute tread/float? It would have been fine with me to lose my $50 deposit after failing the pre-requisite and come back when I'm ready! But not by allowing me to continue with the whole course to expedite my $250 fee and then not getting certified because I cannot tread for 10 minutes! Yes, to know how to swim is important in diving and you don't have to be an athlete to be able to do it. However, this is RECREATIONAL DIVING and it should have been the diving skills that they should focus your grade on the fact that you are fully geared when you do it. This isn't a swimming class! What are the odds of a diver losing both his BCD and fins while diving and that he has to tread in water barefooted? We were never required to be certified passengers when flying in an airplane? Nor you have to know how to parachute to view the sky from the plane? But I'm only talking about their standard here in the US and I want to know what's the standard in the Philippines.
