At present, according to the gym class time, 60- 120 (common) is basically 1 hour for 60 minutes.
At present, according to class hours, 50- 100 (common) is basically one and a half hours and 90 minutes.
All the above are calculated according to the class hours. Of course, sharing or counting by number of people is not ruled out. These are not cost-effective, and the income is unstable, with some pressure and losses.
Physical education class's expenses are relatively high, but wages are often in arrears.
The training class likes to be divided according to the number of people, and it is the teacher who suffers.
The art troupe has low salary, but strict management is guaranteed.
Small classes make more money, but they have great responsibilities.
Of course, the income from taking training courses and being a teacher is another matter. In a word, you will gain some experience by yourself.
Losses are inevitable, and more experience can be avoided as much as possible.
I have been in contact with this since I was 16 years old. The above are personal opinions and ideas. Please consider according to the actual situation. When the monthly salary can reach tens of thousands, a few hundred dollars a month can only be used as living expenses.
