In recent years, it has become more and more difficult for Shanghai to be young and small, and the competition for admission of small "bullfrogs" has intensified. It is suggested that children should be given a comprehensive evaluation before choosing a school every year. Reading Cat International English is mainly to prepare for the entrance examination for primary and secondary schools in Shanghai International School. According to the entrance examination and interview contents of famous international schools in Shanghai (such as Bao Yugang International Primary School and Concord Bilingual), a professional entrance evaluation system was developed. Test children's English listening, speaking, reading, writing, mathematical logic and other aspects in an all-round way, and at the same time, support related courses, check and fill gaps, and help children apply for ideal schools smoothly.
