My son is a sophomore, and a good classmate in the class did one-on-one tutoring on Julei last year, and his final grade improved a lot. He didn't want to fall behind others and asked to go to cram school. After this year, I helped him sign up for a one-on-one tutoring class in mathematics. I told the teacher in advance, just to prepare for the college entrance examination. Now I go to class every week, and the teachers there are very responsible and often communicate with me about my children's learning.
