What is the primary focus of Learn-to-Swim Level 5?

The primary focus of Learn-to-Swim Level 5 is to refine the performance of all six swimming strokes: front crawl, back crawl, breaststroke, butterfly, elementary backstroke, and sidestroke. In this level, swimmers are expected to demonstrate proficiency and improve their technique in these strokes, building upon the skills learned in previous levels. This refinement includes focusing on aspects such as body position, stroke efficiency, breathing techniques, and overall form, which are critical for performance and safety in the water.

The other options, while relevant to swimming and safety, are not the main emphasis of Level 5. Building endurance specifically caters more to advanced training, rather than the stroke refinement focus. Teaching basic water safety skills falls under earlier levels, as well as improving knowledge of water currents, which is often introduced in basic safety education rather than in stroke refinement. Thus, refining the performance of all six swimming strokes stands as the true objective of Level 5.
