I have done both the 2008 college entrance examination paper and the 2009 mid-term examination paper. I think there is little difference in liberal arts, mainly science, physics and mathematics. In 2009, the concepts involved in mathematics were abstract, and the multiple-choice questions also involved patterns, which were rarely mentioned in teachers' teaching. There were more fill-in-the-blank questions than in previous years, which led to great differences. This test is difficult, and it can obviously examine the students' strength. Second, the math test questions in 2008 are very standardized, and the topic is also called easy to use. In physics, the test questions in 2008 are more difficult, a bit like competition questions. Without considerable strength, they can't finish it in an hour and a half. The physical investigation in 2009 was based on basics, and the difficulty was much lower than last year. At this time, it is necessary to examine everyone's intention.
