🔑 Student Code (Start & Submit): 1234 | 🔒 Teacher Unlock Code (Keep Private): 7676
📚 Practice Mode: Direct access without start code. Students can submit via the student code (1234) or take a screenshot, fix questions, and resubmit updated scores.
🔒 Test Mode: Requires the Student Code (1234) to begin. If students leave the screen, the test locks and requires the private Teacher Unlock Code (7676) to resume. Mistakes cannot be fixed.
🔄 Teacher Re-Test: In Test Mode, teachers can authorize a full re-test using the private Teacher Code (7676) from the Final Report, from the lockout overlay, or via the 🔐 header button. Student identity is retained while questions and scores reset.
📝 Unified Code Security: The start code and submit code are the SAME student code (1234). The teacher code (7676) is private to the teacher and never given to students. Once submitted, student identity is permanently locked.
