Which subjects does ExamLens cover?
ExamLens covers 8 major subjects in Taiwan's curriculum: Mathematics (A/B), Physics, Chemistry, Biology, Earth Science, English, Chinese (國文), and History. Questions are aligned with Taiwan's official academic standards and the 108 Curriculum Guidelines.
How accurate is the ExamLens AI solution engine?
The ExamLens AI engine achieves over 98% accuracy on standard textbook problems across all supported subjects. Solutions are generated step-by-step with detailed explanations. For complex proofs or multi-step calculus problems, we recommend verifying key steps with your teacher.

What is the Wrong Answer Notebook and how does it work?
The Wrong Answer Notebook is an automatic mistake tracking system built into ExamLens. Every question you answer incorrectly is saved and organized by subject. Each mistake follows a mastery progression based on the Ebbinghaus forgetting curve: Active (new) → Reviewing (in progress) → Mastered (fully understood). You can add personal notes and re-attempt questions until mastered.
How does ExamLens generate questions from photos?
ExamLens uses advanced optical character recognition (OCR) combined with AI large language models. Simply take a photo of any textbook page, worksheet, or handwritten notes. The system extracts the content, understands the subject context, and generates interactive practice questions at your chosen difficulty level — all within seconds.
Is ExamLens available on both iOS and Android?
Yes, ExamLens (刷題怪獸) is available on the Apple App Store and as an Android APK download. The app supports iOS 14+ and Android 8+ devices. Your account and progress sync seamlessly across all your devices.

This covers both CAP (Comprehensive Assessment Program / 會考) preparation for junior high students and GSAT (General Scholastic Ability Test / 學測) preparation for senior high students. Three difficulty tiers (Standard / Gifted / Olympiad) cater to all levels.
Is my data safe with ExamLens?
Yes. ExamLens uses secure token-based authentication, encrypted data transmission, and platform-native keychain storage for credentials. We never share your personal data or study history with third parties. Your privacy and security are our top priority.
Can parents track their child's progress?
