Today, I had an exam in my Soils Engineering class, and I was stressed about getting a good grade on it. But the questions were similar to the homework problems I've worked on in the last couple of weeks, so I felt more confident. The kicker was when I asked my professor if I needed to make an assumption for one of the problems, and he realized that he forgot to include a measurement needed to solve that problem.
Also for this week in that same class, I've learned that elephants are not suited for soil compaction in Africa: they'll just follow each others' footprints instead of squishing the ground evenly
