I am a rising junior and have 0 extracurriculars related to my school. I am planning on applying to a medical physics graduate program but I work in a research lab (BME) and am working on co authoring and authoring two papers total and am actively involved with my religious organization. However what takes the most time from me is the fact that my sister is autistic and I do everything for her. By everything I mean like 75% but i always help her with homework , take her or pick her up from school most days, take care of her physical needs and even sleep with her. My question is if this is enough extracurriculars for graduate school? Should I not mention my sister? She takes up a lot of my time but also I don't want the admissions committee to feel like I have too many obligations at home and won't want to accept me if I want to go out of state. Thank you for the help!
