What is the unofficial Sansu Kentei Level 8 Quiz?
This free web app is an unofficial 4-choice arithmetic quiz for learners who want to review skills useful for Level 8 preparation.
All questions, choices, hints, explanations, and diagrams are independently created. The app does not reproduce official exam questions, official sample questions, textbook exercises, or workbook content.
Original arithmetic practice by topic
The quiz focuses on original arithmetic problems around large numbers, estimation, multiplication, division with remainders, decimals, fractions, area, angles, units, time, tables, graphs, and word problems.
Each course is designed for short daily review, time attack practice, and repeated learning through My Page records.

Dynamic hints with original diagrams
Hints change according to the question type and show custom diagrams such as place-value charts, number lines, area rectangles, unit conversion arrows, and table or graph guides.
Because the hints are tied to the current numbers in the question, students can check the next step without simply memorizing an answer pattern.
How learners can use this quiz
For a quick warm-up, start with the 10-question mix. For focused practice, choose a topic such as decimals and fractions, area and angles, units and time, or word problems.
The ranking feature adds a light game-like challenge, while My Page helps learners look back at best records and often missed questions.
For parents and teachers
This app is useful when a child says, “I know the rule, but I make mistakes in quizzes.” The 4-choice format keeps the pace light, and the hints show how to organize the calculation or diagram.
Please use it as supplementary practice, not as official exam material. For formal exam information, check the official website.
