Children aged 3-6 need to study 120 classes, about 10 months, and the cost is about 18000 yuan. Children aged 7-9 have a total of 108 classes, and spend about 23,000 yuan each year, ranging in age from 10 to 654,300. The annual study fee is 25,000 yuan, and the fees for children of different ages are different. Fees will be based on students' English scores. Although tuition is a little low for ordinary families, many parents are still willing to give their children a choice because of their high teaching level. However, I suggest that you take your children to experience more before signing up for class, because in contrast, institutions that children prefer and have higher cost performance are the most suitable for children to learn English.
