## What is Otsu4 Pacer?

A question bank alone won't tell you whether you're actually on pace.

Otsu4 Pacer takes your exam date and turns it into a daily quota: how many questions to
answer today to finish every question by test day. Answer one, and the quota drops.

• 90 original questions across 3 subjects, each with an explanation
• A pacer card on the home screen: days left, today's quota, and progress
• Wrong answers go straight into a review list until you get them right
• Try 10 questions per subject for free; unlock all 90 with a one-time purchase (¥500)
• Works entirely offline. No ads. No account.

This is an unofficial, independently written study aid — not affiliated with the exam
authority, and does not reproduce official exam questions.

## Pricing and in-app purchases

Base price: Free.

**One-time purchases**
