Is there any reliable information about learning hegemony at home?

Not reliable. When choosing English institutions for children, we must first ask about the qualifications and teaching methods of foreign teachers. If you don't think it is suitable, don't choose it. Appropriate is the best.

I know a cost-effective institution, which is also certified by European student institutions. Just like CET-4 and CET-6, parents can see the improvement of children's English level! Parents are not allowed to spend money for nothing, and Chinese teachers/foreign teachers can provide one-on-one tutoring online. One class is about 20 yuan, and the experience is free.

The most important thing is to customize the course according to the child's situation, so that the effect can be seen!

I hope my answer can help you, and I wish you progress in your study!
