About this exam

The Yamaguchi Prefectural Public High School Entrance Examination in Science (山口県公立高等学校入学者選抜 理科) is the science component of the prefectural admission selection used by public high schools in Yamaguchi Prefecture for applicants completing compulsory education. It is taken mainly by third-year junior high school students in Yamaguchi, and also by applicants such as those returning from abroad or transferring, who follow the prefecture's published eligibility rules. The paper is written in Japanese and is built on the national Course of Study for junior high school science, so it spans four strands: physics (motion and forces, energy, work and electricity), chemistry (substances and chemical changes, atoms, molecules and chemical equations), biology (living things and environments, human body structure and function) and earth science (Earth and the universe, weather and the environment), plus scientific inquiry, observation and experimentation. Expect a mixture of multiple choice, short answers, written explanations, interpretation of experimental data, tables and graphs, and numerical calculation. Strong preparation means reworking your own experiment notes and notebooks, drawing conclusions from graphs rather than memorising them, writing explanations in complete Japanese sentences with the evidence named, and practising unit conversions and significant figures until they are automatic. Use past papers published by the prefecture to check pacing and phrasing. The prefecture's official site publishes the current year's schedule, subject time limits and question counts; check it directly rather than relying on second-hand summaries.

Common questions

About Yamaguchi Prefectural Public High School Entrance Examination - Science preparation

What is this exam used for?

It is the science paper within Yamaguchi Prefecture's public high school admission selection. The score contributes to selection alongside other subjects, interview or essay components where required, and school records. Each school and course sets its own weighting, so check the recruitment guidelines for the schools you are applying to.

How long is the science paper and how many questions are there?

The current figures are set each year by the Yamaguchi Prefectural Board of Education and published in its admission guidelines and examination schedule. Because they can change, confirm the time limit and question count on the official prefectural site rather than relying on older prep books or hearsay.

What question types appear?

Typically a mix of multiple choice, short one-line answers, written explanations of a few sentences, reading values from graphs and tables, and calculations such as speed, current, concentration or magnification. Experimental settings are common, and you may be asked to describe a control or explain why a result differs from prediction.

How difficult is it compared with regular school tests?

The factual base is ordinary junior high science, but questions are longer and combine topics, so the challenge is reading and reasoning rather than obscure content. Candidates who lose marks usually do so through incomplete explanations or misread conditions, not through missing knowledge.

Can I retake the exam if I am not selected?

Retake and reapplication rules, including any second-round recruitment, differ by year and by school. The prefecture publishes the applicable procedure each cycle. Read the current guidelines carefully and ask your junior high school guidance teacher, who will have the latest documents.

In what order should I study the four strands?

Start with the strand where your school notes are weakest, because all four carry comparable weight. Physics and chemistry reward repeated calculation practice; biology and earth science reward careful diagram and graph work. Finish with cross-topic practice under time, so you rehearse switching between strands.

How should I write the written-explanation answers?

State the conclusion first, then the evidence from the data, then the reason. Name the specific variable, substance or structure instead of writing "it" or "this". Use the terms from your textbook. Graders look for the key term and the logical link, so a short precise sentence beats a long vague one.

What are the most common ways candidates lose marks?

Forgetting units in calculations, describing an observation when the question asks for an inference, ignoring the control condition in an experiment, and writing explanations that never mention the measured data. Also common: leaving a blank instead of writing a partial answer, and spending too long on one graph question.

Where can I find past papers?

The Yamaguchi Prefectural Board of Education publishes entrance selection materials, and many junior high schools keep copies for students. Work through them with a timer, then mark your written explanations against the official answer key to see which key terms you omitted.
