Abstract The enhancement of the current exam question difficulty quantification instrument had contributed to the construction of the difficulty evaluation tool for the extra exam questions pertaining to the chemistry elective exam. A quantitative assessment on the difficulty of the eight extra exam questions for the chemistry elective-exams from 2015 to 2019, which had taken place in Zhejiang Province, an experimental zone for the new Gaokao(National College Entrance Examination), was conducted. As shown from the quantitative assessment, there was a large difficulty variation in terms of the overall test questions. However, in the same academic year, the overall difficulty of two separate chemistry elective exams that may be taken by one student was relatively close. There was a significant difference in competency characteristics and difficulty of the extra exam questions. The extra exam questions for “Fundamentals of Organic Chemistry” (Question No.32) shared an identical difficulty, while the difficulties of Question No.30 (Theory of Chemical Reaction) and Question No.31 (Experimental Chemistry) displayed an obvious fluctuation. On the basis of analysis with regards to the difficulty and relevant factors of the eight extra exam questions, this paper had also put forward feasible suggestions for the improvement of the formulation of exam questions.
