I am a candidate who has just finished taking the college entrance examination this year. In 2008, it was more difficult than this year, but the content was different from now. The finale in 2008 was an inequality, but now it is generally a derivative, and there are some differences, so the comparison is of little significance, and the difficulty is between 0.59-0.6 1. What does that 0. 1 mean? Don't worry about the difficulty coefficient
