Children's English learning needs pure English context. I recommend you to try acaso here, because the course content mainly starts with letters and phonetic symbols, and simple grammar learning. This institution has different levels of English courses: address testing and online one-on-one tutoring, which are highly targeted.
Acaso is also very popular in learning services and pricing. Every selected child will have a professional learning tutor to follow up the whole process to help parents solve all the problems encountered by their children and ensure that their children can study with peace of mind. Let children learn the standard pronunciation, pure thinking and authentic expression from pure foreign teachers, and truly master the English language.
