You can choose a large class in swimming class. Swimming is a basic skill in life. It is not difficult to learn this skill. You just need to master the balance in the water, adapt to the environment in the water, and slowly you can swim faster and faster. Therefore, swimming lessons do not need to be taught privately, but can be learned in a few classes in a large class. For younger students, learning is a very difficult thing, so having students in class can encourage these children to learn from each other, and everyone can learn to swim faster.
Teachers in large classes are more responsible than teachers in private classes, because these teachers are responsible for every child. Under the supervision of many parents, teachers in large classes will also be serious and responsible, so that students can really master swimming skills in a short time. Teachers in private classes only take one child, so the pressure is less, and they will deliberately slow down the class time to earn more money.
If you swim, it is enough to choose a large class for this basic course, and you don't need to choose a private class.
