# Wrong‑Question Notes‑Capture & Recognize Problems · One‑Tap to Print Wrong‑Question Notebooks Wrong‑Question Notes is a math wrong‑question organizing App specially built for Chinese elementary, middle‑school and high‑school students, covering all learning stages from primary to senior high school. Take photos of exam papers or select images from your photo album. The AI automatically recognizes problem content and erases handwritten marks, organizing them into printable wrong‑question notebooks. No more manual copying or stacks of messy paper for reviewing mistakes. 【Capture & Recognize Problems, Auto‑Organize Wrong Questions】 Take photos or import images from your album; process up to 9 exam papers at one time. Circle target wrong‑question areas on images. The AI automatically recognizes questions, multiple‑choice options and mathematical formulas, and sorts them by question type, saving you the trouble of copying each problem by hand. 【Intelligent Erasure of Handwritten Marks】 The recognizer automatically distinguishes printed text from handwritten content. It filters out student answers, red‑ink corrections and revision handwriting while keeping only the original questions. Exported PDF files stay neat and crisp for repeated printing and practice. 【Standard Formula Formatting】 Mathematical expressions such as fractions, mixed numbers and arithmetic formulas are automatically converted to standard formatting. They render as formal printed text in exported PDFs, eliminating non‑standard notations such as "2 and 5/6". 【Intelligent Restoration of Geometry Illustrations】 Common geometric graphics (polygons, cuboids, cubes, number lines, tiling diagrams, etc.) are restored as vector graphics whenever possible. Complex figures can be cropped directly from source images to guarantee full and clear problem content. 【One‑Tap PDF Export for Instant Printing】 After proofreading, generate A4‑sized wrong‑question practice sheets with one tap. Files are grouped by question type with reserved blank spaces for answers. Print preview, system sharing and AirPrint are supported. Print selected individual questions or perform bulk export from your question bank. 【My Question Bank】 Saved problems are stored in your personal question bank, managed in groups by recognition records with custom‑tag support. Review your history at any time, select problems for re‑practice and export them for printing again. 【Review Reminders】 Review reminders are automatically scheduled after each scan. Push notifications will alert you at scheduled times, helping you truly work through your mistakes instead of forgetting them right after organizing. Target Users: • Elementary Students: Organize wrong answers from homework and unit tests for printing and re‑practice • Middle‑school Students: Systematically build review materials for high‑school‑entrance exams and practice grouped by question type • High‑school Students: Efficiently archive exam‑paper mistakes and export special‑practice sheets anytime • Parents: Organize wrong‑question worksheets for children and print practice papers to reduce tutoring workload Wrong‑Question Notes has zero splash‑screen ads and no distracting complicated features.
