Each verdict takes your own. Yours is stored against the stack's, so “where is it wrong most often” is a question with an answer.

1. Work is the right way up Board orientation is upright at 0 degrees

   Text is oriented horizontally and upright in all frames (Frames 1-9).
   seen · 100% confident
2. Your view ok weak bad can’t tell
3. Writing is legible at video size Text and handwriting are clearly legible

   Handwritten definition 'When an object changes its position with respect to time is called motion.' is neat, well-spaced, and easy to read (Frames 4-8).

4. Your view ok weak bad can’t tell
5. The work fills the frame Not applicable to a board session
   seen
6. Nothing distracting in shot Not applicable to a board session
   seen
7. The student's problem is established Question is captured at the start of the session

   The question 'What is motion' is shown as a text box in the upper left corner from Frame 1 onward.
   seen · 100% confident
8. Your view ok weak bad can’t tell
9. Work proceeds in followable steps Board work accumulates clearly

   The definition accumulates sequentially across Frames 3 to 5 and remains clearly displayed on the canvas.
   seen · 100% confident
10. Your view ok weak bad can’t tell
11. It reaches an answer Conceptual explanation is fully answered

    The complete definition is written out by Frame 5 and elaborated with motion types through the end of the session.

12. Your view ok weak bad can’t tell
13. Something was actually written board went from 1.65% to a peak of 5.24% covered (+3.59 points), ending at 2.32%

    Very little appeared on the board.

14. Your view ok weak bad can’t tell
15. The concept is named before the working Tutor explicitly names the concept

    The tutor states: 'What is motion? So, motion is when an object changes its position.'
    heard · 100% confident
16. Your view ok weak bad can’t tell
17. Explained rather than jumped to the answer Concept is explained thoroughly throughout

    As this is a purely conceptual question, the tutor explains the definition and contrasts it with rest and types of motion.
    heard · 95% confident
18. Your view ok weak bad can’t tell
19. Solved step by step, not in one leap Spoken explanation develops logically

    The tutor logically progresses from the definition of motion to rest, rectilinear motion, and curvilinear motion.
    heard · 95% confident
20. Your view ok weak bad can’t tell
21. The session opens properly Tutor greets and states the question

    The tutor exchanges greetings ('Good afternoon. Yes, good afternoon.') and confirms the topic ('What is motion?') at the beginning.
    heard · 100% confident
22. Your view ok weak bad can’t tell
23. No long dead air 5 gaps over 6.0s, 66s total (36% of the session), longest 19s

    Silence is below -35.0dB — a crude measure on a phone microphone, so treat a low count as weak evidence rather than proof the tutor was talking.
