About this app

Practice with authentic past exam questions up to the passing standard.

This is a past exam question and practice test app for the Registered Salesperson Examination. It includes actual exam questions (2025, Hokkaido/Tohoku Block common, 120 questions total) published by Hokkaido Prefecture, with sources clearly indicated under the CC BY 4.0 license.

■ 120 Actual Questions, Exactly as They Were Asked
These are actual questions from the real exam, not commercially available practice questions. Correct answers have been machine-verified against the published correct answer list. You can check the trends, wording, and trick questions using authentic examples.

■ Explanations for All Options, Sources for All Questions
Not only are the correct answers provided, but explanations of "why and why" each option is incorrect are included. Furthermore, the source is clearly indicated for all 120 questions, and the basis for the explanations can be verified using the Ministry of Health, Labour and Welfare's "Guidelines for Examination Question Creation (April 2026)" and e-Gov legal data (Pharmaceuticals and Medical Devices Act).

■ Covers Legal Amendments
The weakness of past exam questions is legal amendments. This app compares questions with the latest guidelines (revised April 2026), and for questions affected by the revisions, both the "correct answer at the time of questioning" and the "current system" are clearly indicated.

■ Reasons for Failure: Subject Score Requirements
The passing criteria are "70% or higher of the total score, and 40% or higher in each subject" (from the implementation guidelines). The pass/fail simulation determines your current position based on the correct answer rate for each subject and specifically notifies you of the subjects you are lacking.

■ Mock Exam with the Same Structure as the Actual Exam
The mock exam consists of five chapters: basic knowledge of pharmaceuticals, the workings of the human body, major pharmaceuticals, pharmaceutical laws and regulations, and proper use. The half-mock exam (60 questions) is free for the first time, and the full-mock exam (120 questions, actual exam format) includes a pass/fail breakdown by subject.

■ Errors Can Be Reported and Corrected Immediately
Errors in questions and explanations can be reported anonymously from within the app. If an error is confirmed, the correction will be reflected for all users without waiting for an app update. The correction history is published within the app.

■ Free for up to 10 questions - No ads
You can try up to 10 questions for free. The free limit is not reset daily. All features can be unlocked with a one-time purchase; there are no subscriptions, ads, or account registration. Learning records are saved on your device.
