An English educator said, "If these five teachers come to Eton College, they will certainly be very happy. Because the children here are very capable and will not let China down. " Oliver Kramer, who was the provost of Eton College in 1997-2008, commented. Kramer said that secondary schools in Britain are divided into private schools and public schools, which are very different. In excellent private schools, classroom discipline is equally strict, and most private middle schools are boarding schools. However, the "elite" education in British private schools is no easier than that in China. Therefore, private secondary schools such as Eton College and Scott Middle School gather 7% students in Britain, but 50% students are admitted to Oxford and Cambridge every year. However, in order to enter a private school, children must be prepared from the age of six, and then undergo cruel screening (including family conditions) before they can enter a top private middle school. Public schools like BBC Documentary have low study pressure, and students are much less likely to be admitted to prestigious schools. After three years, their income and class will be quickly separated from the prestigious schools.
