Mathematics is so important, who can speak it well? I don't know whether the topic is their online class or information. If you take an online class, you have heard about Changyu Probability several times. Not bad. You can't speak fast, and you feel calm. Don't worry, your temperament should be mucus. In the previous generation, I had participated in the postgraduate examination for several years, taking Li as the main reference. It seems that the elderly in their seventies are full of energy, have a good conversation, have a reasonable structure and have a good summary. He said he would go to graduate school himself. Need a certain foundation. In the popular words now, classes are all dry goods. Just like a parade, there are no objects, and every object is the product of n numbers. This n number is located in other columns in other rows. Determine the symbol of the item according to the parity of the array. The summary of the queue in Li's course or textbook is the same as other routes in the other ten times. The old man said that it is enough to know so many marching ceremonies. So domineering.

Qiu Yi personally thinks that Li Yongle is not a fairy figure on the postgraduate entrance examination line. I think what he said is the best. Ye Qiu watched video courses for at least four years and learned a lot from them. Review the textbooks in his class first, and then students with a better foundation will have a much better effect. He will run the postgraduate entrance examination content through his classes, rather than laying the foundation for you through his materials. He will often test the knowledge points, key points, difficulties and test sites of the postgraduate entrance examination, and some counseling materials will focus on the foundation and be more detailed. As a result, you may have read the whole book, but your actual combat ability is still very long.

Whose class you listen to depends on your background. If there is no foundation, it is absolutely no problem to listen to Tang Jiafeng. Basically, the whole process I heard from Tang Jiafeng was very delicate and asked good questions. Zhang Yu's words are very insightful. Tang Jiafeng is recognized as better in the industry. Zhang Yu's comments are mixed. Still recommend Tang Jiafeng. In addition, I recommend another math teacher, Fang Hao. Listen to his class and you will know the location of the Great God. Basically all problems can be killed in seconds.

Finally, let me talk about Lin Li. Four words, arranged by Li Linyu! Li Lin can just buy several sets of papers he published last month. Then, about a week before the exam, some questions about his oppression appeared on the internet, which were basically questions about the test paper. Can you imagine how you felt when you saw 18 and 19 in the exam?
