Difficult. According to relevant data, the average score of science mathematics in Anhui was only 55. What concept? A student in No.1 Middle School, who is usually the top student in the whole school, has never scored 140 in mathematics, but actually only got 1 18. According to the invigilator of the college entrance examination, when 80% of the students in an examination room finally get the test paper, the last three big questions are all blank. Because the math test paper is too difficult, a line in Anhui is nearly 60 points lower than in previous years! It is equivalent to directly dropping from one line to three lines.
