DSE MistakeBook
Review mistakes, score higher
Free · Designed for iPad. Not verified for macOS.
Now on iPhone and iPad. Capture a mistake, come back before you forget, and quiz yourself. Everything stays on this device.
Turn wrong answers into marks on the next exam.
Mistake Book is a private mistake journal for students. Photograph a question you got wrong, review it before you forget, and quiz yourself on your own errors — so the same slip does not cost you again.
HOW IT HELPS YOU SCORE
Exams reward what you can still recall under pressure. Logging every mistake, then coming back on a schedule, is one of the most reliable ways to raise your result. Mistake Book follows the forgetting curve (1, 3, 7, and 14 days) so you revise while the memory is still there to save.
CAPTURE IN SECONDS
• Take a photo, pick from your album, or type the question
• On-device OCR for Traditional Chinese and English — then edit any line
• Save the correct answer, your wrong answer, and why you missed it
• Tag by subject, topic, and mistake type
REVIEW BEFORE YOU FORGET
• A due list for today — mark a question reviewed when you are done
• Local reminders: daily when items are due, plus a weekly progress summary
• Study quiz: up to 3 past mistakes, even if they are not due yet
• Reveal the answer only after you have tried it in your head
SEE WHERE TO WORK HARDER
• Totals, this week, due vs up to date
• Breakdowns by subject and mistake type
• Share a summary card when you want a snapshot of your progress
