I would have her emphasize the elements of her involvement that aren't focused on a medical career. Running/organizing events, fundraising, etc. she can talk about how her experiences showed her that those were her strengths and helped her refine her interests.

We have a similar situation. DD is a whiz at using computers and has done amazing things on her own, but is interested in humanities.

Freshman and sophomore year, my daughter was sure she wanted to do pre-med or nursing in college and thought she loved science - thus, she got uber-involved in the health occupations club at school. It's probably her most "accomplished" EC - she's president, has raised tons of
Money for cystic fibrosis, etc. Well, junior year rolled around and AP Chem, AP bio and AP calc hit her like a freight train and she's decided she wants nothing to do with a career path involving health care or really anything super heavy in math and science. She is a phenomenal writer and also has taken six years of Spanish, so she thinks she wants to do international business or relations. This is reflected in her ACT score, too (35 English, 35 reading, 30 science, 26 math.)

So, my question is this: in the admissions realm, what are the thoughts about being super invoked in an EC that's kind of the opposite of what one plans to do or major in, and is the area in which she "struggles" the most in classes and on standardized tests? (I put that in quotation marks because obviously her scores are still good, and she still manges to pull A- and B+s in those classes.)
