You need to call your individual schools - its up to them. Because you will be an MD student FAFSA will NEVER again require your parental info to submit to schools. Your schools however will likely require it for need-based loans. You need to call the individual schools to see if they will get huffy about you not putting your parental info on the fafsa in addition to the other applications. But in my experience if you want institutional need-based aid then YES you do have to put parental info on the FAFSA.
