My boyfriend and I are going to be at CSA for the first time this November and we are both really excited. My boyfriend is already scuba certified and I know he really wants to dive while at CSA. He is going overseas for work from June to October so I was thinking of surprising him and getting certified at home while he is gone. I was just looking for some advice about how hard it is to get certified. I am a decent swimmer but by no means advanced or maybe even intermediate lol. How much swimming do you have to do to get certified? Also, in general does everyone swim individually or the whole class at a time. I hate the thought of others watching me Thanks in advance!
