## What is AI?

The exam-prep app for engineers working with machine learning and generative AI on Azure. Covers the new AI-300 (Microsoft Certified: Machine Learning Operations Engineer Associate — the successor to DP-100). 500 original questions built to the official Study Guide, a full-length mock exam, and three-layer explanations in your language. One-time purchase, no subscription, fully offline.

■ What makes this app different
- An exam-prep app for the brand-new AI-300 (GA 2026, succeeds DP-100)
- Five-language display with an English toggle — official exam translations are often literal, so switch to English to grasp the real meaning
- All 500 questions carry three-layer explanations: per-option rationale / overall explanation / Microsoft Learn references
- Code questions (CLI, YAML, Python, Bicep) verified against official references
- One-time ¥1,480, fully offline — no subscription, no connection needed

■ 500 original questions, built to the official Study Guide
Written to the AI-300 blueprint (5 domains, 14 tasks). Completely original; never copied from official questions, docs or portal screenshots. Four formats: single choice, multiple response, ordering, matching. Case-study and "does this solution meet the goal?" formats restructured for studying.

■ Explanations that train best-vs-second-best judgment
Real-time vs batch, serverless vs managed, PTU vs on-demand — the exam tests fine distinctions. Every distractor explains why it falls short in that situation.

■ Full-length mock exam
Reproduces the real exam (~120 min, pass 700/1000). Per-domain weak-spot analysis afterward. Question count is customizable.

■ Structured study
- 5 domains (MLOps infrastructure / ML lifecycle / GenAIOps infrastructure / GenAI quality & observability / GenAI optimization)
- 5 study modes (sequential / shuffle / weak-spot / favorites / review)
- iCloud sync across devices

■ What is AI-300?
An Associate certification on MLOps/GenAIOps with Azure Machine Learning and Microsoft Foundry — training, deployment and monitoring of models through evaluation and optimization of generative AI. The successor to DP-100 (retired June 2026).

■ Pricing (one-time, no subscription)
- First section + one mock are free to try.
- ¥1,480 one-time unlocks all 500 questions and the mock exam. No monthly fees.

■ Requirements
iPhone / iPad. Works fully offline.

## Version history (last 5 releases)

### 1.2.4 — 2026-08-03

We improved the quality of the question content in this update.

- Revised the questions, answer choices, and explanations for 22 items to improve technical accuracy and make the correct answers clearer
- Updated wording for commands, configurations, and operational scenarios to align with official Azure Machine Learning and Microsoft Foundry documentation
- Applied the same corrections across Japanese, English, Korean, Brazilian Portuguese, and Traditional Chinese

### 1.2.3 — 2026-07-05

Updated our support and official website information. No changes to app functionality.

### 1.2.2 — 2026-07-01

Improved how the "average score of your last 3 mock exams" on the Home screen is calculated. It's now a weighted average (total correct ÷ total questions) instead of a simple average, so mixing exams of different lengths reflects your true performance more accurately.

### 1.2.1 — 2026-06-29

Improved the tap area for answer choices. You can now select a choice by tapping anywhere on its row — including the empty space, not just the text. Applies to both Study and Mock Exam.

### 1.2.0 — 2026-06-19

• Added a Reset Study History option.
From Settings → Study Data, you can return every question to unanswered and start fresh. Your mock exam results and bookmarks are kept.
