Why Chinese people good at math and science?
First of all, the education system in China is different. In China, everyone has too much pressure. Chinese people usually think going to a good school means get a better education, and Chinese people really care about education for their children. In order to go to a good school, students need to do a lot of homework and practice questions, and teachers always gives a lot of tests and exams to students. Practice makes perfect, so later students begin good at solving math and science questions.
Secondly, Chinese students are two or three years ahead of students in other countries in math and science. In China, students begin to learn physics, chemistry and biology in grade 7. And they keep learning them until grade 12. But in America, students only learn science from grade 9. And each subject they only study for one year. When I came to high school in America, students are still struggling in algebra, while in China students are learning calculus. So when Chinese students come to America, everything become so easy for them.
