Difficult. In 2024, the examination questions of postgraduate mathematics are more difficult than in previous years, and the amount of calculation is also greatly increased. According to candidates, this year's math exam is not only difficult to think about, but also the calculation process is quite complicated. Some World War II candidates said that compared with last year, the difficulty of this year's math test questions increased significantly. Last year, I was able to get above 140 easily. This year, I feel it is very difficult to get 120. This increase in difficulty puts forward higher requirements for candidates' mathematical foundation and problem-solving skills. Therefore, the second volume of mathematics in 2024 is very difficult to test.
