About the Chiba Entrance Science Exam
The Chiba Public High School Entrance Examination science paper is one of the five subject papers in the prefecture-wide academic examination administered by the Chiba Prefectural Board of Education for admission to prefectural public high schools. Chiba holds the main examination over two days in mid-February (February 16-17 in 2027) under identical conditions across the prefecture, followed by a makeup examination (February 25 in 2027). Day 1 covers kokugo and mathematics in 50 minutes each and English in 60 minutes; day 2 covers science and social studies in 50 minutes each; every subject is scored out of 100 points. The science paper follows the MEXT Course of Study for junior high school, drawn in good balance from the first field (physics and chemistry) and the second field (biology and earth science), and emphasizes interpreting observation and experiment data, graphs, and tables. Results are combined with the junior-high school report (chousasho, multiplied by a school-set factor K between 0.5 and 2) and school-set tests; there is no single passing score. This page provides 100 original English-language practice items, including simple calculation and data-interpretation questions, as a study adaptation — original items, not official past problems.
Assessment
The real Chiba science subject is one of the five academic subjects (kokugo, suugaku, eigo, rika, shakai) of the prefecture-wide entrance examination administered over two days under identical conditions across the prefecture (the R9 / 2027 main examination is scheduled for February 16-17, 2027, with a makeup examination on February 25, 2027; the preceding R8 / 2026 examination was held on February 17-18, 2026). The science paper is given on day 2, lasts 50 minutes, and is scored out of 100 points, following the MEXT junior-high science curriculum drawn in good balance from the first field (physics and chemistry) and the second field (biology and earth science), with items ranging from knowledge recall to experiment data analysis. This local bank is an English-language study adaptation aligned to the same curriculum content, including simple calculation and data-interpretation items; the items are original and are not official past problems, and the MCQ format does not reproduce the official written-explanation work.
