The BBC posted this video in June. Chinese students at the University of Illinois-Urbana/Champaign explain why they prefer to study in the USA.
The main reason: they can study what they want. In China, your major is pre-selected for you, based on your performance on the college entrance exam (gaokao). High school students list five preferred majors on their exams, and the exam section with the highest score determines which of the five possibilities is assigned.
So, this is why I’ve had students who prefer physics and math, but ended up being Business English majors. Their gaokao scores on the physics and math sections were too low.
Parents are also fed up with the Chinese gaokao system. If they have enough money, they will send their children abroad for their university education, sparing those kids three years of intense, high pressure preparation for the gaokao.
