I overloaded in college and took an additional Philosophy course called Business Ethics in order to satisfy a degree breadth requirement, (so that I could take more courses related to my major in later semesters). This course is not part of my GPA but still counts as a credit for graduation and on my transcript it is coded as
Degree Requirement, Not included in Average. A friend of my mine said that I should explain why I overloaded, especially an ethics course on my optional essay, because it may seem like this was done as a penalty of some sort by my school. I want to use that essay to describe my GPA and life circumstances and I'm a bit confused as whether or not I should explain this course. To be clear, I have never been part of any disciplinary matters at my school, but I want to avoid confusion of any kind. Although I would also not want to draw attention to something that is clearly stated on my transcript and focus more on extenuating circumstances. Am I thinking about this too much? Is this a common occurrence? Side note, I also took a year off of college (due to one of my parents having serious organ failure), so I wanted to explain my GPA around that time in my essay (as it took a bit of a nosedive).
tl;dr, Are overloading courses common in applications to MBA schools? And are adcoms seasoned with the various course codes that are stated on applications or should I explain this in order to remove any doubt?
