How to practise and review a question

Choose one-question practice for a short session, or a mock exam to work through a set of questions. This guide uses practice, which you can try without registering, to show how to learn beyond memorizing an answer number.

1. Select a year and start

   On the practice screen, choose a year with published questions and start. Questions are selected randomly. If no year is available, there are no published materials to use. If loading fails, use the retry action shown on the screen.

2. Check what the question asks and answer

   Check whether the question asks for a correct or an incorrect statement, select a choice, and confirm your answer. Even when you are unsure, jot down the wording or condition behind your choice so you can compare your reasoning with the explanation.

3. Read every explanation and its sources

   After answering, check the core rule, overall explanation, and the reasons for every choice, as well as whether you were correct. Read corrections to false statements and the cited provisions or sections. Compare these with your own reasoning. Source entries show the title, publisher, and applicable version.

4. Describe the missed condition before moving on

   Classify a mistake as an unfamiliar rule, a missed condition, or a misreading of the question. Even after a correct answer, reread the explanation if you cannot explain why it is correct. Consider which conditions would change the conclusion. Practice does not let you request the same question repeatedly, so keep your own notes on topics and sources to revisit.

An example review note

Suppose a question asks for an incorrect statement but you choose a true one. Separate an unfamiliar rule from a misreading of the task, then check the explanations and cited sources. A short note in the following format makes the next review more focused.

Task: choose an incorrect statement. / My reasoning: I overlooked a condition. / Checked: explanations for every choice and the relevant source section. / Next time: check the task, who the rule applies to, deadlines, and exceptions. This is an example of a study method, not a quoted published question or an explanation of the law.

Guest use, member use, and mock exams

Guests can use practice and published mock exams. Guest exam state and results are temporary and may be lost when storage expires or restarts. Registering later does not transfer those guest results to an account.

Exams started as a member can be reviewed with their explanations in that member's history. Before starting, choose standard or exempt form and whether to use a time limit; check the save status while answering. Explanations appear after results are finalized. Member exam history and the immediate explanation in one-question practice are separate features.

Checking years, sources, and corrections

Sources shown after an answer include the publisher, title, applicable version, and an access date where recorded. Match the citations in the explanation to the source; linked sources also let you read the original. The access date records when a source was consulted, not when a law took effect.

Check the question's year together with the applicable source version. A year label alone does not establish one legal reference date for every question or mean the material matches current law. For topics affected by legal or institutional changes, check the explanation's applicable period and the conditions of the exam you intend to take.

If you suspect an error, use the report link after answering or in an exam result. Identify the relevant choice or explanation, your reasoning, and the source section. Use the contact link below for general questions. Do not include personal information in reports.

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).

Members can publish sessions started with All sections and a best streak of at least 1. Each member's best published record appears once per year and period; ties share a rank. Periods use the session's finalization time in Japan. Test materials, disabled accounts, withdrawn questions and major corrections are excluded.

Your public name and visibility settings are shared by mock exam and practice rankings. Saving these settings does not publish a new result.
