This also depends on your English foundation, whether you have passed CET-4 or CET-6, and so on to comprehensively evaluate your English level to help you see the most suitable courses. Students with good English level can choose intensive classes, problem classes and model test classes in large classes (about 25 students), and the cost is about 3000-8000. Students with poor English level may need to attend small classes (6-8 students) or one-on-one full-time classes, and the cost is about 10000-30000. I suggest you go to school in official website. I hope my answer can help you.
