Single choice · Answered
One bank, every screen
Review against source documents on your computer, then practice a few questions on your phone. Your question banks, progress and mistakes stay together.


From document to mastery
Automation saves time. You decide what gets published. Clear review states help keep unreliable imports out of your practice.
Skip manual entry. Zhixu extracts questions, options, answers and source locations from your materials.
Keep clear results and review uncertain or blocked questions separately, so you can focus your attention.
Confirm a version for practice. Later changes create a new version and preserve earlier practice records.
Practice in sequence, at random or with mistakes first. Questions leave the default mistake queue after consecutive correct answers.
Built for trust
Follow a question from its original source to each published version and attempt. Correcting an answer later preserves the facts of earlier practice.
Keep data sources and location clues, so you don’t have to rely on guesswork when finding problems.
Formal changes to question stems, options, and answers will not quietly overwrite old content.
Past answers stay linked to the question version used at the time, so progress can be recalculated.
AI with boundaries
Built-in AI and external agents propose changes for review. Check the evidence and impact before creating a new version.
