Write in such a way that you dont sound that you are giving accusses for your bad grades. May be a good way to approach this essay is explaining the circumstances and how it affected your priorities to focus on activities outside of studies. In the end you want to potray that you comprised your grades but it helped you to learn how to cope with difficult situations (along those lines). I hope you get my point.
I dont think that school will require you to turn in the medical records of your mother.
I'm currently applying to several b schools, but I have bad grades due to my mother being sick, which required me to travel home a lot to take care of her. Any suggestions on the best way to write this essay? Do I talk about the struggle only or the struggle and what I learned about myself? I only have 250 words for many of these schools.
Also, should I include a document in my application to prove that this was true (a note from my mother's doctor)? Will schools ask for verification?
