Oliver was in the Advanced class this year. They learn new strokes, increase their endurance, perfect their stroke and learn fun things off the diving board such as flips, dives, and back dives. They first jump in with their clothes to see what it would feel like if they accidentally fell in the pool and what they need to do. They had to tread water for a long time and back float for a long time. Oliver's favorite part is doing flips off of the diving board. I can't believe how fearless this boy is. You did an AWESOME job, Ols!
