On the course page#

  • Topics and subtopics are collapsible. Drag to reorder; the handle appears on hover.
  • Each lesson shows its card count and a status: ready, generating, or needs attention (the audit flagged something).
  • Regenerate rebuilds a single lesson from its source material, which is far cheaper in credits than rebuilding the course.

On a card#

  • Click the text to edit it in place. Formatting supports bold, lists and maths (LaTeX between \( and \)).
  • For questions, the correct answer and accepted alternatives are editable; Fill cards accept a list of synonyms.
  • Images come from the CDN gallery or your uploads. Up to three images show as a grid, more as a carousel.
  • Hints appear after a wrong answer. Keep them short.

Preview as a student#

Every lesson has Preview, which runs the real practice page in a frame without recording anything. Join your own class as a student to see the course exactly as they do, with hearts and streaks.
