OCR & parsing
Scanned banks go through OCR and are parsed into questions, options and answers.
A 4,811-question trainer for Taiwan's construction safety-supervisor exam
Study material for Taiwan's Class A occupational safety and health supervisor exam (construction) is scattered across handouts, regulations and scanned PDFs. We used OCR and cross-checking to turn it into one practice site with spaced review, wrong-answer drills, weak-chapter reports, mock exams and cross-device sync — a structured sprint for the last three days.
The challenge挑戰
What we set out to fix
Questions are everywhere
Handouts, regulations and several scanned PDFs in different versions are hard to work through.
Sources disagree
Different sources give different answers, and scans introduce recognition errors.
Time is short
Working people only have a few days before the exam and need to know what to study first.
What we built做法
How we built it
Cross-checking
Banks from several sources are compared, with answer conflicts, OCR doubts and version issues flagged separately.
Spaced review
Review follows your answer history, with wrong-answer drills and weak chapters at a glance.
Mock exams
Mock tests that match the real exam: 80 questions, pass mark 60.
Cross-device sync & backup
One sync link carries progress between phone and computer, with export for backup.
