I am another newbie my husband and I have taken our classes and are due to retake our certification dives this weekend. Our first attempt we passed the snorkel skills test and then couldn't clear our ears and were kicked out of the water...lol guess our instructor thought it better not to blow our ear drums. So we have cleared our head colds and are going back this this weekend. I'm a little nervous since I haven't been in the pool in 3 weeks, and haven't had the chance to do ny mask clears or retreavals. The local dive shop recommened we check out this site since we are also planning a vacation for our tenth anniversary and its all planned around us getting certified. hoping for the best. crossing my fingers and thinking about following the smallest bubbles.
