Yamaguchi Prefectural Public High School Entrance Examination - Mathematics

It is a written test combining short-answer items, some multiple-choice basics, and constructed-response questions where you must show calculation steps or write a proof or explanation. Expect a spread of difficulty from routine calculations to multi-step problems. The official paper structure and any changes are announced by the Yamaguchi Prefectural Board of Education.

The current time limit and question count are set by the prefecture each year, so check the official examination guidelines published by the Yamaguchi Prefectural Board of Education rather than relying on second-hand numbers. In practice, the paper is long enough that pacing matters: practise with a timer so you learn how much time to leave for written explanations.

Most items test standard junior-high content, so a solid grasp of the textbook gets you a large share of the marks. Difficulty comes from the later reasoning items, which combine topics and require justification. Aim to secure all routine marks first; the discriminating questions are usually the proof and explanation items, not the calculations.

Retake and reapplication rules, including whether a later selection round exists, are set by the prefecture and by each school. Ask your junior high school guidance teacher or check the Yamaguchi Prefectural Board of Education's entrance selection information for the current year. Do not assume a second chance is automatic.

Finish the standard syllabus in school order: expressions and equations, then functions, then geometry and proof, then data and probability. After that, work domain by domain on past papers, weakest area first. Keep a notebook of errors by topic; repeating the same mistake is the most common reason marks stall.

First sit a full paper under time to find your baseline. Then redo it without a time limit, writing out every step, and compare with the official answer key. Finally, reattempt the items you lost after a week. The prefecture's published past papers are the closest guide to the real style and wording.

They look for a logical chain: state what is given, state what you are proving, cite the geometric or algebraic property you use, and reach the conclusion. Write in complete sentences, label points and angles consistently, and do not skip the reason for a step. A correct answer with no justification often earns little credit.

Typical losses are arithmetic slips under time pressure, misreading a condition such as a range or a unit, leaving a proof without stated reasons, and spending too long on one hard item. Another frequent problem is an unclear graph or diagram. Build checking habits and practise deciding quickly when to move on.

The Yamaguchi Prefectural Board of Education publishes the current entrance selection guidelines, including schedule, application procedures and any fees, on its official website and through junior high schools.
