Quality and usage policy

Checks before publication

Questions, correct answers, explanations, legal basis and applicable dates are reviewed before publication. Importing question data does not make it available to learners automatically.

How we plan to use AI

AI may assist with drafting questions and explanations. People check the material before publication; AI output alone is not treated as verified content.

Questions and corrections

Use the report link after answering a question or in an exam result. Reports are saved privately for administrators. Verified corrections are published separately alongside explanations and past results. Major defects stop new use of the affected revision and exams. Original answers and scores are kept; past scores are marked when a major defect is found and are not recalculated automatically.

What the materials can tell you

This service is an unofficial learning resource and is not provided by the official exam organizer.

Practice questions and mock exam scores will support your learning. They do not guarantee the questions on the actual exam, a passing result or the accuracy of every explanation.

Review saved exams

Practice up to 10 questions from the versions saved in this result. New practice answers are temporary and never change your exam score or ranking.

Rankings

Participation is optional. Compare your best published score with members who took the same year, exam revision and timed format.

Only results you explicitly share are counted. Each participant's highest score in the selected period is shown. Equal scores share the same rank (1, 1, 3); completion speed does not break ties. Months are based on the result's finalization time in Japan Standard Time (JST).

Change your public name and whether previously shared results are visible. Saving these settings does not share a new exam result.
