## What is CampusDing?

Study math in Chinese, one question at a time. CampusDing includes primary-level questions and enrichment questions for elementary and secondary school stages. The app interface and question content are in Simplified Chinese.

Search by question text or topic. Take or select a photo of one question, recognize the text on your device and check it before searching. Photos are not uploaded.

Choose sets of 5, 10 or 20 questions. Multiple-choice items use the source answer; open-response items let you assess your work against a reference answer. Review mistakes, save favorites and export study records stored on your device.

No account, ads, backend or AI service. Each question includes its source and license information.

CMATH covers primary grades 1–6. TAL-SCQ5K uses broad school-stage labels, not exact secondary grades or US curriculum alignment. The collection currently covers math only and does not solve questions outside the included bank. Check uncertain answers with a teacher or parent. Younger students should use the app with a parent.
