Oh man, the amount of times I told students that maybe they don&#x27;t belong in university is quite high. I used to teach (alongside a prof) Physics for Biologists. Constantly I&#x27;d get remarks like: &quot;But what are we supposed to do all these hours between class and homework guidance hours?&quot; (What am I, your entertainer??), &quot;Why can&#x27;t I use my graphical calculator, this is bull shit!&quot;, This is not why I choose biology!&quot;, and my favorite &quot;Why won&#x27;t you just let me fill in the formulas and work with the intermittent numbers?&quot;<p>I&#x27;d tell them: You are an electron in it lowest possible energy and you want get to your highest excited state without adding energy. That simply does not work. If you can&#x27;t handle it, perhaps you do not belong here where you are actually challenged and are required to meet that challenge.<p>It was also crazy how often they complained but turned out not to have even tried the homework on their own.
