Li Yongle Six Sets of Volumes: The overall difficulty is 3.5 stars, the selection and filling are better, and the details are in place, but sometimes, well, it is too detailed, and the big questions are ok. Generally speaking, it is closer to the real question.

Tang Jiafeng's eight sets of papers: the overall difficulty is 3 stars, not too difficult, and the topic is not novel. Mainly based on investigation and calculation. You can do it if you have more time, but don't do it if you don't have much time. (After the exam last year, many people said that making paper soup and soup was the biggest winner. I'm not saying that the soup is bad. After all, I'm with him, but this statement is groundless. After all, I didn't feel much improvement when I made these eight sets of papers. To tell the truth, calculating this kind of thing has little to do with what paper I do, but with my usual accumulation and attention.

Li Lin's six sets of papers: the overall difficulty is 3 stars, and the questions are not bad. Personally, I think the six sets of papers in 2 1 year are a little simple, but they are in line with the real difficulty of odd years, and even years should not be enough, but maybe Li 6 may be more difficult this year?

Li Lin's four sets of papers: the overall difficulty is 4 stars, and the difficulty is close to even-numbered years. Published around 65438+February, the paper is well written. The knowledge points are in place, and the big questions are well done, which can be used to benchmark the real questions of the year. As for how it was published this year, it is not clear.

Zhang Yu's eight volumes: the overall difficulty is five stars. This thing is really a bit difficult, and it doesn't matter if it's not done well. However, if you score high, you should still understand all the suggestions. There are some problem-solving skills that still need to be mastered. I remember when 2 1, Zhang Ba's big problem of line generation especially liked to examine the reversible linear transformation method, probably because the second generation students took the exam in 20 years.

Zhang Yu's four sets of papers: the overall difficulty is four and a half stars, which is much better than Zhang Ba, but there is still some difficulty. Even years are slightly bigger than the real questions, but this year's questions are more difficult, so it is still recommended.

* * * Create transcendence: * * Create difficulty by four stars, and surpass difficulty by four and a half stars. The topics are all good. The main difficulty lies in the investigation of ideas, so this is also highly recommended.
