It's the end of April and the beginning of May every year, and the second model contest in Hefei is coming soon. This year, due to the epidemic situation, the second model test may be conducted directly from early May to mid-May. For students who have just resumed classes, time is tight and tasks are heavy. In previous years, the second model examination paper in Hefei was more difficult, especially in Luyang District. It is the most difficult of all districts in Hefei. So that the average score is particularly low, it is easy to hit students' self-confidence. Therefore, the three models are relatively less difficult. On the one hand, with the entrance examination approaching, it is very important to build students' confidence. On the other hand, it is closer to the difficulty of the senior high school entrance examination. It is conducive to making students more aware of the rules of the senior high school entrance examination. Although the overall score of this year's chemistry paper has dropped by 20 points, the length of the exam has not changed. It shows that the difficulty will not decrease, but may increase. Two questions were added to the multiple-choice questions, and the score of each multiple-choice question was reduced by one point, while that of the non-multiple-choice questions was reduced by one question. In this case. The time it takes to do the problem, there are more knowledge points that can be examined on the test paper. This is a new challenge for students.
