To learn SAT, Shanghai is the most international metropolis in China, so it is best to train SAT in Shanghai, because there are better teachers in Shanghai, but there are not many professional SAT trainees in Shanghai. If you want to have a better SAT score in a short time and apply for a better university in the United States, Shanghai Midland SAT should be considered, because it is taught in small classes and the teachers are more professional. Of course, you can also compare it according to your own situation. For example, if you are in a basic class or have a certain basic level, you can choose different classes.
