Although the senior high school entrance examination is not as complicated as the college entrance examination, I think China students need to be fully prepared before taking the written examination in British schools, because:
China students usually have a solid basic knowledge, but they are not familiar with the examination contents of British schools; English students' knowledge of mathematics is usually not as good as that of China students, but they start studying science (physics, chemistry and biology) earlier than China students. For all subjects except mathematics, even if the English foundation is good, it is still necessary to further improve English, because the contact with English literature is limited and the vocabulary needs to be expanded.
