Mei Sen International Children's English is good. From the perspective of mathematics, Mei Sen International Children's English not only establishes mathematical concepts in English environment, but also enables students to master mathematical terms firmly. Two children have advantages over only children. In Mei Sen's class, the topics and interviews assigned by the teacher can be conducted at home first. The boss's English foundation is not as solid as the second one, because the second one came from K, and the boss was transferred directly from S 1. In pronunciation and standardization, the second child is slightly better. If the age is right, I think it is more suitable for children to start from the K stage in Mei Sen.
