It is very difficult to match individual big questions reasonably.

20 15 At 5: 00 p.m. on June 7th, the bell rang at the end of the college entrance examination for mathematics, and the candidates walked out of the examination room one after another, smiling, calm, slightly tired or preoccupied. Whether it is a science candidate or a liberal arts candidate, the overall feeling of mathematics is that it is difficult to match reasonably, but some big questions are difficult and have not been worked out.

"This math exam has simple questions and tricky questions, and the difficulty matching is also reasonable." Jiang Yuchen, a senior three student in Yulin Middle School, was the first person to walk out of the examination room. As a science student, she told reporters that the math exam is generally difficult, almost as difficult as the simulation questions organized by the school at ordinary times, but the 19 big question about finding the trigonometric function of quadrilateral interior angle is very difficult, and she didn't finish it. Except for the derivative function of 2 1 problem, other problems are relatively easy and smooth.
