Speak more and use more in oral English practice. Decisively recommend ef children. My children have been studying in their classes for two years since the sixth grade. They have always been representatives of English classes, cultural and recreational committees, and often go out to participate in English speech contests on behalf of the school. In fact, oral practice can not only improve children's English level, but also improve their self-confidence and exercise their abilities. My child used to be shy, but studying at EF gave her great confidence. Now I meet her at school every time and see her and diplomacy.
