In the past, I've had students call my problem sets “emotionally trying”
&gt; On exam day you are just emotionally devastated looking at the problem not knowing where to start<p>I honestly understand the frustration,but not the &quot;emotionally devasted&quot; part.<p>Emotionally devasted to me  means losing someone.<p>When I studied CS I went to the exams knowing very well if I had studied or not and how much, and did not expect anything.<p>The exam was the easiest part, you either know how to solve the problems or don&#x27;t and walk away<p>If something was out of the scope or &quot;impossible knowledge&quot; I would book a personal appointment with the professor to talk about it.<p>For any too hard to solve exam, there have been more than one that I passed having honestly not spent enough time studying.<p>Luck is an important factor and usually it levels out in the long run.<p>also those kinds of failures teached me to focus on the things I could solve instead of those that I couldn&#x27;t and eventually go back and give them a second shot. It boosts your confidence and helps look at the problems from a different angle.
