Let me talk about my initial feelings: at present, studying and thinking at school are synchronized with children's thinking training, but it is difficult to register. I sit facing south and start a new class without saying that I am a freshman; I haven't seen Shangpin's textbooks yet, but I can try, so I plan to explore further. If more freshmen register, I can start a new class. I haven't been there because I'm in Puxi all the year round. At present, I really want to hear the opinions of parents of students studying in these three or other Olympic math classes. After comprehensive consideration, thank you, please advise!
