What is this?
itlearn.bojiangz.com — ITパスポート 過去問ノート, a study app for the Japanese IT Passport exam built around the real past questions.
Non-native learners of Japanese technical exams get blocked by kana/kanji recognition, not by concepts. アクセシビリティ → accessibility → 可访问性, seen once, sticks. So every question keeps its original Japanese text with a Chinese and English translation you can show or hide, and every explanation is available in all three languages.
What's in it
| Page | What it does |
|---|
| Today | Daily plan: mistakes to redo, reviews that are due and new questions (picked by the exam's field ratio). New users start with a 20-question baseline. Also shows progress over the 2,900 past questions, an exam-date countdown, weak topics (low accuracy × often tested), accuracy by field against the pass rule (600/1000 overall, ≥300/1000 in each field) and 3 glossary terms for today. |
| Practice | One question per screen: browse by exam or by topic, practise with your own settings, or redo your mistakes. Japanese question text with a ZH/EN translation toggle, enlargeable figures, and a trilingual explanation after you answer. |
| Mock exam | 100 questions in 120 minutes, as in the real exam: a random draw in the official field ratio (strategy 35 / management 20 / technology 45) or one whole past exam. Scored 0–1000; results only at the end. |
| Textbook | Syllabus-aligned trilingual study units — 63 topics, 244 units — with key points, figures and check questions taken from the past exams. |
| Glossary | 1,395 textbook terms, searchable in Japanese, Chinese and English, each linked to its textbook unit and related past questions. |
| Record | Totals, reviews due over the next 7 days, questions per day (5 weeks) and accuracy by topic. |
| Settings | Exam date, daily review limit, daily new questions, default translation visibility, interface language. |
The interface language switches between 日 / 中 / EN. Your learning record is kept in the browser on your device; no account is needed.
AI tutor (bring-your-own-key preview)
An AI tutor (AI 先生) lets you ask about a question, a term or a textbook unit, and get a review of your weak topics. It is a preview that needs your own Anthropic API key: the key stays in your browser, which calls Anthropic directly. Open it from Ask AI Tutor after answering a question or on a glossary term, or from Settings; it is not in the main navigation yet. A full release is planned.

Development
Requires Node ≥ 20.9 and pnpm 11.
# Clone
git clone https://github.com/hakupao/it-passport-learning
cd it-passport-learning
# Install (from the workspace root)
pnpm install
# Web app
cd apps/web
pnpm dev # http://localhost:3000
pnpm build
# Checks
pnpm test # Vitest
pnpm lint
pnpm test:e2e # Playwright e2e
# Quiz answer-key cross-check (repo root)
cd ../..
pnpm check:quiz:ci # committed data only
The app reads the committed corpus under data/ip/, so it runs locally without any environment variables. Without Redis and an owner key, the learning record simply stays in the browser.
Environment variables
All optional.
| Variable | Description |
|---|
OWNER_KEY | Site-owner secret. Opening any page once with ?owner_key=<OWNER_KEY> sets the owner cookie, which enables record sync and question feedback. Unset = nobody is owner. |
UPSTASH_REDIS_REST_URL / UPSTASH_REDIS_REST_TOKEN | Upstash Redis for the owner's record sync and question feedback (KV_REST_API_URL / KV_REST_API_TOKEN are also accepted). |
QUIZ_DATA_ROOT / TEXTBOOK_DATA_ROOT | Override the data directory (default ../../data/ip, relative to apps/web). |
| Metric | Value |
|---|
| Past questions | 2,900 (29 exams, FY2009–FY2026) |
| Textbook | 63 topics, 244 units (13 on v2) |
| Glossary | 1,395 entries |
| Locked decisions | 203 (D-001 … D-203) |
| Session logs | 73 in docs/discussion/ |
| Unit tests | 1,264 (Vitest, 110 files) |
License
- Code, pipeline, ADRs — License pending (consult the repo owner before redistribution).
- Past-exam questions — Based on the past exam questions published by IPA; copyright belongs to IPA. The text has been OCR-extracted, cleaned, classified by syllabus topic and translated, so it differs from the original.
- Textbook and explanations — AI-generated for this project.
