I am in Grade Two in Hankou. If I have not been trained before, I should think twice. Because if you are not interested, it is useless to cultivate Excellence. It is better to let nature take its course. In addition, if you are not good at math, don't train excellent students. The topic of cultivating excellent students is generally difficult, only for those students with medium and high level, and students with low level are still important. Whether Jingchu is good or not depends on the individual. There are many educated people there, which should be good, and it varies from person to person. Personally, I think that you can get high marks by expanding what you have mastered in school a little, and there is no need to cultivate Excellence.
The above is just a personal opinion.
