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 Not applicable to a board session
   seen
2. Writing is legible at video size Writing is clear and well-contrasted against the dark canvas.

   Text in both English and Hindi across frames 2 to 8 is neatly written and easy to read.

5. Nothing distracting in shot Not applicable to a board session

6. The student's problem is established The question is clearly visible in the initial frame.

   Frame 1 shows the question 'What is coulomb's law' at the top left.

7. Your view ok weak bad can’t tell
8. Work proceeds in followable steps The tutor clears the initial diagram to write text instead of keeping both.

   The diagram in Frame 2 is cleared in Frame 3 to write the text definition across Frames 3 to 8.

10. It reaches an answer The session ends before the mathematical formula of Coulomb's Law is written.

    Frames 7 and 8 only show the verbal statement in Hindi and an incomplete English definition without the mathematical expression.

12. Something was actually written board went from 2.33% to a peak of 9.98% covered (+7.65 points), ending at 9.98%

14. The concept is named before the working The tutor explicitly states the topic at the beginning.

    The tutor says: 'What is Coulomb's Law? Let's explain to you what Coulomb's Law is.'

16. Explained rather than jumped to the answer The tutor sets up the core physical setup before writing the full statement.

    In Frame 2 and early transcript, the tutor sets up two point charges $q_1, q_2$ separated by distance $r$ before proceeding to write the formal definition.

17. Your view ok weak bad can’t tell
18. Solved step by step, not in one leap The definition is built up gradually line by line.

    Frames 3 through 8 show text being added incrementally alongside spoken explanation.

20. The session opens properly Tutor greets the student and confirms the question.

    In the transcript: 'Good evening, Alshifa. Yes, Alshifa. I will solve your problem. Question is here. What is Coulomb's Law?'

22. No long dead air 0 gaps over 6.0s, 0s total (0% of the session), longest 0s

    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.
