- A preview before every import, with questionable items flagged to fix or skip
- Open question files shared from other apps straight into QuizBao
- Edit, move, copy and merge questions any time; find and merge duplicates

Practice your way
- Practice mode: in order, random or unseen first; shuffled options; instant feedback
- Study mode: answers and explanations shown for a fast review
- Mock exam: timed random papers, automatic scoring and a pass line
- Mastery mode: clear the questions you know so the set keeps shrinking
- A random 10-question quiz when you only have a minute
- Mix several banks in one session

Review what you got wrong
- Wrong answers go to your mistake book automatically
- Get a question right a few times in a row and it is marked mastered
- Spaced review on the forgetting curve, with reminders
- Weak-spot analysis finds the chapters and question types with the lowest recent accuracy
- Favorites, typed notes and handwriting stay with each question
- Export mistakes, favorites and notes to Word (ready to print), ZIP or Excel

Track your progress

Optional AI tools
- AI Import: scanned PDFs, photos and messy Word or Excel files become a clean bank, even with answers printed at the back
- AI explanations: tap after answering to see the reasoning and key points
- AI study analysis: a report with diagnoses, chapter advice and a 7-day plan; only statistics and bank or chapter names are sent
- AI answer filling: questions without answers are solved by two different AI models and filled in only when they agree
