The size of the school, the teacher's teaching time and so on. Set their own charging standards and prices. Every school is different. But on the whole, it's not much difference. So it doesn't matter how much tuition.
Because you are cheap, you are cheap, and you don't have much money. Expensive, it won't cost much. The key is where can I learn good professional skills? Where can I learn formal skills? Choosing a school is very important. You should focus on choosing brand schools. Not how much it costs.
