My bestfriend and I are planning to go for the scuba diving course in Andaman in the months of April may. I'd like to know more about it as in how much would it cost for a month, about the stay ,how a normal day looks like,difficulty level( we both are swimmers) ,if we can do it under 10k etc. Any information would be highly appreciated.
