Of course, there will be a difference in the cost of enrolling in the small class of SAT and the large class of XDH. Class size will also affect the average cost.

Compared with second-and third-tier cities, the cost of SAT training courses in Shanghai will be relatively high because of the relatively high cost and relatively concentrated teaching resources. And because there are many institutions, it will remain relatively fair in market selection.

Based on these factors, the amount of Shanghai SAT summer school is determined by the annual price, different institutions, different duration and different number of people, and the cost is slightly higher than that of the test language. This is because language learning has a pan-popular foundation. From the perspective of economics, as long as it is more popular, its marginal benefit is relatively low.
