We've completed a massive refactor of the exam module, unifying workflows by removing legacy components and centralizing exam patterns, approval lifecycles, and student/admin interfaces. Significant focus was placed on improved handling of optional sections—including auto-scoring logic that respects 'choose-count' constraints—and transitioning offline grading to a vision-first AI approach using Gemini. The student experience has been streamlined with clearer exam instructions, sequential question numbering, and better feedback on exam statuses.
