Well here's the story. Me and My fiance both want to get certified, the problem, is she's not a very good swimmer, we went and did a discover scuba, to see if she can handle being underwater, and she did great. But when we got ready to the 200 yard swim, she had alot of trouble, i think she can do it, but now i'm worried about her being able to do the 10 min. tread. I'm probably going to get her in some lessons, but do any of you instructors have any advice that will help her out, or anything i can do. Thanks alot.
