How long you need to learn depends on your own needs. If you want to study major, take a substitute class in the future or like jazz dance very much, and have a few hours of free time every day, you can choose a jazz dance tutorial class, usually 1 month, 2 months or 3 months, and the specific time can be chosen according to your own learning purpose; If it's just fitness or hobbies, choose a daily membership class.
The tuition fee is determined by the class you choose. If you choose different classes, the price will definitely be different. For example, I am now in the Queen Dance Studio in Zhengzhou. Their membership classes are more than one year 1000, and they have classes every night. The remedial class is more than two thousand a month. This is a professional and systematic training. It takes six hours to attend class every day, which is different. It depends on your own choice.
I hope I can help you!
