It’s not funny. I planned to do the same during Fall 2019. Because the failing grade will not be counted toward the cumulative GPA (there is a limit on how many times we can do that for failing grades), luckily, I could file a petition to drop the class during week 7 (proceeded in week 8).
I think I can explain why I failed that class in the essay, whereas my GPA was perfect instead of getting a B because of my mental health in the most comfortable class, which was hard for many of my classmates, but I got an easy A.
