Undecided about whether to become a doctor or biomedical researcher

Hey everyone,

I’m currently undecided about whether or not I’d like to attend grad school as a phd for biomed or an md to treat patients. I’ve read that colleges seem to prefer very specific career goals in letters (is this true?) and was wondering if this uncertainty could hurt my acceptance chance at competitive schools.

I know for certain id like to major ungrad, but am unsure about grad school and career. would it be in my best interest to pick one route and write about it in detail, at least for my app?

thank you
