What is the Math Kentei Grade 3 Unofficial Study Quiz?

This is an unofficial free 4-choice study quiz for learners who want to review junior-high level mathematics while preparing for Math Kentei Grade 3.

All questions, options, explanations, numbers, graphs, and diagrams in this app are original. The app does not reproduce official exam questions, official sample questions, textbooks, workbooks, mock exams, or entrance exam materials.

Original course structure for broad junior-high math review

The quiz uses an original course structure based on general mathematical facts, formulas, units, symbols, and common junior-high math learning themes.

• 10-question basics mix
• 20-question numbers, expressions, and square roots
• 20-question expansion and factoring
• 20-question equations and simultaneous equations
• 20-question linear functions and graphs
• 20-question geometry and angles
• 20-question Pythagorean theorem, circles, area, and volume
• 30-question probability and data
• 50-question applied problems
• 100-question comprehensive challenge

Dynamic hints with original diagrams

Hints change depending on the current question. The app shows original SVG diagrams for equations, graphs, triangles, circles, square roots, factoring, probability, and data when they help understanding.

Challenge history, best records, rankings, and often missed questions are saved so that repeated review is easy.

How to use this quiz for study

Use the short courses when you want to check one topic, such as square roots, factoring, equations, functions, geometry, probability, or data. Use the 50-question and 100-question courses when you want a broader review session before a test or practice day.

Each question is designed to make you choose a method: simplify first, factor first, substitute into a function, draw a figure, count possible outcomes, or check units. The goal is not memorizing answer patterns, but becoming faster at noticing what kind of math is needed.

For students, teachers, and parents

Students can use the app for quick self-study, teachers can introduce it as a light review activity, and parents can see which topics a learner often misses from My Page. Because the questions are original, the app is meant to support daily practice without replacing official materials or school instruction.

For official exam information, grade descriptions, application rules, and published sample materials, please check the official Math Kentei website directly. This page only provides an independently created practice quiz and does not reproduce official exam content.
