The overall difficulty of this year's test questions has increased compared with previous years, and the flexibility has increased. The overall difficulty of multiple-choice questions is slightly higher than in previous years; The investigation form of experimental questions is novel and requires students' basic knowledge and flexibility. The calculation of big questions has a clear hierarchy, and the calculation difficulty has decreased, but the comprehensive application ability of knowledge has improved; The choice of examination questions is quite satisfactory and the transition is smooth. The difficulty of multiple-choice questions, experimental questions and calculation questions is low, and they are all designed with continuous difficulty from easy to difficult. The proportion of easy, medium and difficult is reasonable, and the middle difficulty is the main one, which broadens the distribution of difficulty and effectively distinguishes most level candidates. Most of the questions are not difficult, but the calculation questions are still challenging, which requires students' ability and has obvious selection effect.
