SCENARIO LEARNINGBuild judgment
Build judgment
through scenarios,
not memorization.
When learning qualifications in the AI era, simply memorizing terminology is not enough. Themes that are close to practical matters are organized into problem sets that can be repeated on the iPhone.
COMMON VALUEOne consistent learning experience
One consistent learning experience
across all six certifications.
Read the official Study Guide as primary information, reconstruct it as an original problem, and build up your understanding with explanations and references for each option.
Officially aligned
Create questions based on the exam scope using Microsoft Learn / GitHub Docs, etc. as primary information.
Your language + English
Understand in Japanese and get used to English service names and exam expressions.
Scenario focused
Rather than memorizing terminology, you can check practical judgments using questions.
COMPAREDo not let English-only
Do not let English-only
web materials stop your progress.
Videos and web teaching materials are useful for grasping the overall picture. What you need right before the exam is an environment where you can repeatedly check whether you can solve the problem.
| Candidates' worries | Common learning | Nichful Microsoft Certification App |
|---|---|---|
| Mainly English and difficult to understand | It’s easy to just watch English materials and videos | Japanese + English written together |
| Lack of confidence in design and operational decisions | I feel like I understood it just by memorizing the terms. | Scenario-based problem practice |
| I want to try it first and then decide. | Difficult to see contents before purchase | Check questions and explanations by free download |
| I want to continue solving it | Easy to assume PC | Easy to follow every day with iPhone |
| I want to learn while traveling | Many teaching materials require communication. | Completely offline |
| I'm concerned about additional costs | There are many course units and subscriptions. | Purchase outright. Updates are free forever |
