Audit's summary: The student asked a question about cells, and the tutor explained the discovery of cells by Robert Hooke and Antonie van Leeuwenhoek. The tutor clarified the difference between dead and living cells and the methods used by each scientist. The tutor also checked for the student's understanding and addressed any doubts.

Hello, good afternoon, Ashfa, welcome to Filo. इस समझाना है अश्पाँ 1674 B.C. they have also found these cells but they have found the living cells. Where did they do it? In the water of the pond, they have found the living cells by using simple and small drugs. Like bacteria, protozoa, all these. So what was in the person? Did you understand Asfand? Yes. What are the doubts? Yes. Okay. Okay. Now, no doubt about you? No. Okay. Bye. Okay. Bye. Bye. Bye.

  9. Work proceeds in followable steps Working and annotations progress systematically down the page.
    The tutor underlines and circles relevant points sequentially from Frame 3 to Frame 8.

  11. It reaches an answer The explanation of the presented points was completed.
    The tutor highlighted the relevant points through frame 8 and concluded the discussion with the student.

  13. Something was actually written board went from 17.95% to a peak of 44.38% covered (+26.42 points), ending at 23.96%
    measured
  14. Your view
  15. The concept is named before the working The tutor mentions living cell discovery directly without a formal conceptual introduction.
    The transcript shows the tutor diving straight into: '1674 B.C. they have also found these cells but they have found the living cells.'
    heard · 85% confident
  16. Your view
  17. Explained rather than jumped to the answer The tutor explains the notes line by line.
    The tutor explains the historical discovery of living cells as presented in the notes right from the start of the interaction.

  18. Your view
  19. Solved step by step, not in one leap Explanation moves step by step through the points.
    The tutor steps through the details (discovery year, organism, pond water) systematically while annotating in frames 3-8.

  20. Your view
  21. The session opens properly The tutor greets the student warmly at the start.
    The transcript records: 'Hello, good afternoon, Ashfa, welcome to Filo.'

  22. Your view
  23. No long dead air 2 gaps over 6.0s, 13s total (8% of the session), longest 7s
    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.
    measured
  24. Your view
Observations judged, but not counted as the lab objecting
  1. The camera holds still Not applicable to a board session
    Not counted: Measured over 183 known-bad and 29 known-good camera sessions (2026-09-21): raised on 87% of the bad and 86% of the good, and the motion distributions are the same shape — median frame difference 25 on the bad set, 27 on the good. No threshold on this number separates them, so it is reported and not counted.
    measured
  2. Exposure is usable Not applicable to a board session
    Not counted: Same two sets: it raised 6 of 183 known-bad and 2 of 29 known-good sessions. Both too few to mean anything, and the brightness distributions overlap almost exactly. The earlier reading that it 'fires more on clean sessions' was two sessions out of twenty-nine — noise, not an inverted rule.
    measured
  3. Understanding of the concept is checked No conceptual check question was asked.
    The tutor only asked generic understanding checks like 'Did you understand Asfand?' and 'What are the doubts?' without testing conceptual comprehension.
    Not counted: Raised on 87% of known-bad and 80% of known-good sessions. The criterion is honest about why in its own `why`: the transcript has no speaker labels, so a real check and a rhetorical 'ok?' are often indistinguishable, and the bar ends up one almost no session clears. Still judged and shown, because reading it beside a recording is how it gets better.
