&gt; Talking (and not teaching) to 200 ppl over 2 hours is not time allocation to &quot;me&quot;.<p>I&#x27;m not talking about the lectures (they&#x27;re useless unless most of the time is spent on Q&amp;A). There is always a certain amount of time teachers must spend with their students individually, upon request. Smart students use that time, the others may not even know they&#x27;ve got a right to harass their teachers occasionally.
