Winning the championship easily is not only an analytical question, but also an examination question. Qidong and one lesson and three exercises pay attention to test questions, and the notes of the champion pay attention to explanation. The three-year simulation of the five-year senior high school entrance examination is mainly the senior high school entrance examination. Generally speaking, Qidong is a little more difficult, but taking the champion lightly is easy to expand children's thinking. Personally, I think it is better to win the championship lightly, because it has more questions and has little to do with the difficulty of learning. It is important to understand all the problems.
