The first hourly turned out to be a notch too hard. Maybe because I wetted it with Chat GPT who
solved the problems with flying colors. Even tough problems like |vec(i) i||vec(i) i| which
tries to confuse (and was as expected not even solved by one student in this class) and which
was posed as a bonus problem, was no problem at all for Chat GPT 4.
I have no doubt that the first exam was also considered challenging because we had no opportunity for
review as the 4th of July was snatching away 3 hours of our classes this summer. This happens every
few years unfortunately.
