Hello, actually, I think the training class is really useless and expensive. The training class is just the foundation. So I suggest you practice basic dribbling first, and look for videos and the like online. Every contact must practice arm pain, so that muscles can form muscle memory. A situation, for example, when watching TV, don't idle your hands. Holding the basketball in your hand can improve your hand's feel of the basketball (called the sense of the ball). The most important thing is to play more in actual combat, which is very helpful to you. My conclusion is that playing well means being abused by experts, so you will meet all kinds of experts and exercise yourself in all aspects, so that you will make rapid progress! Finally, I wish you success!
