How can I put it? My daughter studied there for a summer vacation. At first, she didn't want to go there because she thought it was always too strict. Later, she gradually began to get used to the learning atmosphere there. Mathematics was her nightmare when she went there. When she took the math exam, she couldn't sleep. After studying there for a month, her math score rose by about 40 points. I found that her attitude towards mathematics has changed. Sometimes she will work at home until 1 1 p.m. To tell the truth, the teachers there are all very good. The charge is indeed a little more expensive than ordinary small classes, but the effect is what I see. Adults work hard, and ultimately it is for the children. As long as their grades improve, I think it is worthwhile to spend more money. After all, children don't have that much time to waste.
