Tall man. The tuition fee of Washington University in St. Louis is about 40,000 to 50,000 dollars a year, and the living expenses are about 50,000 to 70,000 dollars a year, equivalent to 350,000 to 490,000 yuan. This is an expensive expense for most families in China. However, Washington University in St. Louis offers generous scholarships to students, who can also work to earn living expenses while studying in the United States. So the actual cost is not as big as expected.
