In fact, I personally think that if your child is determined, it is no problem to improve mathematics within one year. My daughter's partiality is serious, and she has never been very good at math. I sent him to the front line of excellent study in her fifth grade summer vacation, and his math score was much higher than that before preparing for the exam in junior high school. She was admitted to Class 3A of junior high school and successfully admitted to Huaying Middle School.
