शरीर में होने वाले परिवर्तनों के लिए उत्तरदायी अंतःस्रावी ग्रंथियों द्वारा स्रावित पदार्थ का क्या नाम है?

Audit's summary: The student asked a question in Hindi about the name of the substance secreted by endocrine glands responsible for changes in the body. The tutor explained that this substance is called a hormone and wrote the answer in both English and Hindi. The tutor also provided a brief explanation of endocrine glands and illustrated the concept with a diagram related to growth hormone.

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.

Work is the right way up Canvas is upright at 0 degrees

Text and drawings in frames 1-8 are oriented upright at 0 degrees.

Writing is legible at video size Handwriting and diagrams are clear and legible

The writing ('Hormone', 'Growth Hormone', Hindi script) in frames 3-8 is clearly legible against the dark background.

It reaches an answer The question is fully answered and explained

The core answer ('Hormone') is stated and illustrated with stick-figure growth and secretion diagrams by frame 8.

The concept is named before the working The core concept/answer is explicitly named

The tutor states 'ये इसको कहते हैं हॉर्मोन.' and writes Hormone / हार्मोन in frame 4.

Your view
Explained rather than jumped to the answer Direct answer was given immediately before conceptual breakdown

The tutor states the answer ('हॉर्मोन') right after reading the question before explaining the meaning of endocrine glands and hormones.

Solved step by step, not in one leap Explanation breaks down the terms with visual aids

The tutor draws growth progression (frames 4-6) and gland secretion flow (frames 7-8) while breaking down the terms.

The session opens properly Tutor greets the student and reads the question

The transcript shows the tutor greeting ('Good afternoon bhai, awaaz aarahi hai?') and confirming the question before beginning.

Your view
No long dead air 1 gaps over 6.0s, 8s total (5% of the session), longest 8s

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.

Observations judged, but not counted as the lab objecting

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
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
Understanding of the concept is checked No deep conceptual check question was posed to the student

The tutor explains unilaterally and only asks rhetorical understanding prompts ('you understand what secretion means') without testing the student's conceptual grasp.

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.
