I believe this question is optional - an opportunity explain a bad grade or bad semester.Just to clarify, "
Is there any specific hardship to which you would like the committee to give special attention in evaluating your application? Please briefly explain below. (Include any geographic, language, economic, academic, physical, or mental factors.)"
Is this question mandatory...? I assume not everyone has a specific hardship to write about, and it seems rather open-ended since it is asked in a way that suggests "let us know if you have one."
