What is the teaching quality of "Master Class" in Moke Education?

The teacher teaches well and is responsible for the children. My children are in the fifth grade, and their English scores are always behind in every exam. Junior high school is about to start, and I want to choose a school and be admitted to Huanggang Middle School. I am very worried about her grades. Later, I learned that a friend introduced that there is a counseling institution called Master Class near here, and the teaching quality is very good. My children have never been consulted. I listened to my friends and took my children to sign up. I want her to go to counseling to see if the child's grades have improved after half a month of the final exam. But my friend recommended it to be true. My child was not very good at English subjects a few years ago and never got full marks. After this tutorial, he got a score of 100 in English test, which made me more confident in the Mohist teacher's class and kept my children here until the students started school. Thanks to the teachers of Mok Education for their hard training of children, so that my children can regain their motivation to learn. Thank you!
