Gaokao Chemistry is a province-administered selected subject in many reform models, commonly a 100-point, 75-minute written paper in 3+1+2 provinces, though Shanghai, Zhejiang, and other local systems differ. It has no national pass mark; scores support admissions ranking and subject-combination rules. This local bank provides 100 original MCQs for focused practice, not a replacement for province-specific timed papers.

About the Gaokao Chemistry Exam
Gaokao Chemistry assesses senior high-school chemistry foundations and chemical reasoning under China's curriculum-standard and Gaokao evaluation framework. Preparation should cover amount of substance, chemical equations, atomic structure, periodicity, bonding, reaction energy, rate, equilibrium, electrolyte solutions, electrochemistry, common inorganic and organic substances, experimental inquiry, data interpretation, green chemistry, materials, energy, and environmental contexts. Because Chemistry is administered through provincial paper and selected-subject arrangements, candidates should pair this practice bank with the latest notices from their own provincial admissions examination authority.
Assessment
Gaokao Chemistry is administered through China's national/provincial ordinary higher-education admissions framework. In many 3+1+2 reform provinces, Chemistry is one of the reselected academic-proficiency selective subjects chosen from Chemistry, Biology, Geography, and Ideological and Political Education; it is commonly a 100-point, 75-minute written subject with selected-response and non-choice chemical reasoning tasks. Exact item counts, paper structure, score conversion, test date, and admissions use are province-specific. Regional exceptions matter: Shanghai's 2026 Chemistry graded exam is scheduled for 60 minutes, and Zhejiang's selected-subject implementation measures use 90-minute selected-subject exams. This local practice bank follows the official curriculum and examination-outline themes but uses 100 original MCQs for practice.
Time Limit
Often 75 minutes in many 3+1+2 provincial schedules, such as Hubei's 2026 Chemistry slot from 8:30 to 9:45 on June 9; Shanghai lists a 60-minute Chemistry graded exam in 2026, and Zhejiang selected-subject exams are 90 minutes. Confirm the current schedule locally.
Passing Score
No national pass mark. Chemistry contributes to admissions through provincial score or grade-conversion rules when selected; provincial control lines, institutional plans, subject requirements, and ranking determine outcomes.
Exam Fee
Varies by province or municipality; registration and any exam fee are handled by provincial admissions examination authorities. (Ministry of Education of the People's Republic of China / National Education Examinations Authority, with provincial admissions examination authorities)

Frequently Asked Questions
Is Gaokao Chemistry a 100-question multiple-choice exam?
No. Official Chemistry papers vary by province and normally combine selected-response with constructed-response or fill-in chemical reasoning. This page contains 100 original four-option MCQs for local practice, so the 100 count refers to this practice bank.
How long is the Gaokao Chemistry exam?
Many 3+1+2 provinces use a 75-minute Chemistry selected-subject slot; Hubei's 2026 schedule lists Chemistry from 8:30 to 9:45 on June 9. Other local systems differ: Shanghai lists a 60-minute Chemistry graded exam in 2026, while Zhejiang selected-subject exams are 90 minutes.
What score is needed to pass Gaokao Chemistry?
There is no national pass score for Chemistry. In provinces where Chemistry is selected, the score or converted grade contributes to admissions ranking under local rules and university subject-combination requirements.
Does every province use the same Chemistry paper?
No. Chemistry paper structure, scoring conversion, timing, and whether it is part of a 3+1+2 selected-subject model, graded exam, or other local arrangement depend on the province or municipality.
What should I practice besides these MCQs?
Use your province's official or released full papers, timed non-choice experiment and calculation problems, industrial-flowchart questions, organic synthesis reasoning, data-table interpretation, and a topic-coded error log.
What topics are most important for Gaokao Chemistry review?
Official curriculum and outline guidance emphasize basic concepts, structure and periodicity, chemical reaction principles, inorganic and organic substances, experimental inquiry, and chemistry in materials, energy, environment, life, and society.
