He doesn’t seem too strict. I took freshman comp last semester, and we had to write four three-five page essays. They did get tedious any annoying, but when the semester was over, I realized that the class helped me become a more critical writer than I once was.
A lot of professors are lax about bathroom breaks and tardiness, but occasionally, you will get a professor that really doesn’t like those things. Also, if this class is 50 minutes, it isn’t unrealistic to expect students not to have to use the bathroom unless it is an absolute emergency. Most college students can control their bladders.
I found that I would always get way more annoyed than the professor when students would come in late, especially if the class is later in the day. Being late is disruptive and shows lack of respect for the professor.
