About this exam

The Gunma Prefecture High School Entrance Examination in Science (群馬県公立高等学校入学者選抜 理科) is the science component of the academic achievement test used by Gunma's public upper secondary schools to decide admission. It is written for students finishing compulsory education - typically third-year junior high school candidates, including those applying through special selection or returning from abroad - and it is administered by the Gunma Prefectural Board of Education. Candidates should confirm the current schedule, application route, and scoring arrangements on the board's official site, since these are published there each year and are not fixed by this page.

The paper draws on the full junior high science curriculum, split across four strands: physics (motion and forces; energy, work, and electricity), chemistry (substances and chemical changes; reactions and ions), biology (organisms and environments; inheritance, cells, and reproduction), and earth science (geology and the solid Earth; weather and astronomy), plus a slice of scientific inquiry. Expect a mix of multiple-choice items, short numerical or one-line answers, and longer written responses that ask you to explain a reasoning step or interpret experimental data. Graphs, tables, and experimental setups are central, so practise reading values off a graph and stating a conclusion in a sentence.

Preparation that works: work through your textbooks and school notes first to lock down terminology and formulas, then drill past papers under timed conditions, and finally write out full explanations for the written-response items rather than just checking the answer. Keep a notebook of errors by topic and revisit it weekly.

What you'll study

Common questions

About Gunma Entrance Science preparation

What is the format of the science paper?

It combines multiple-choice questions, short-answer items requiring a word, number, or formula, and written-response questions where you explain a result or interpret data. Questions are organised around physics, chemistry, biology, and earth science, often anchored to an experiment, graph, or table you must read carefully.

How long is the exam?

The time limit and timetable are set each year by the Gunma Prefectural Board of Education and published in its entrance-selection guidelines. Check the board's official site for the current year's schedule rather than relying on second-hand information, and practise full papers within that limit.

How difficult is it compared with regular school tests?

It rewards understanding over recall. Routine textbook questions appear, but the discriminating items ask you to apply a concept to unfamiliar data or explain why a result occurred. Students who memorise facts but cannot justify an answer typically lose marks on the written-response section.

Can I retake the exam if I do not pass?

Retake and reapplication rules depend on the selection round and the year's guidelines, so confirm them with the Gunma Prefectural Board of Education. Do not assume a simple second attempt is available; plan your preparation around a single sitting and ask your school for the current rules.

In what order should I study the four science areas?

Start with the areas you find weakest, because improvement there is fastest. Then cycle through all four in short, regular blocks rather than finishing one completely. Physics and chemistry benefit from repeated calculation practice; biology and earth science from diagram labelling and explaining processes in your own words.

How should I use past papers?

Do your first paper untimed to identify gaps, then switch to strict timing. Mark every error by topic and by cause - misread graph, forgotten formula, incomplete explanation. Rewrite written answers in full sentences and compare them with the model answer's structure, not just its content.

What are the most common ways candidates lose marks?

Leaving written explanations vague, omitting units in calculations, misreading axes or scales on graphs, and answering only part of a multi-part question. Another frequent loss is describing what happened without stating the underlying principle the question asks for. Read each prompt twice and check how many parts it contains.

Do I need to memorise formulas and chemical equations?

Yes, but with understanding. You should be able to recall common formulas and write balanced equations, yet the exam often asks you to choose or rearrange a relationship rather than plug into a memorised one. Practise deriving what you need from definitions and units.

Where can I find official details on scoring and results?

The Gunma Prefectural Board of Education publishes the current selection guidelines, including scoring and result announcements, on its official website. Your junior high school's guidance office also receives these documents. Use those sources for any figure, as numbers change between years.
