Lawrenceville vs Magnet school

My DD has been accepted to Lville as a day student and an academy of health and medical sciences in our county. She is very keen on becoming a doctor. If she goes to Lville she will need to likely give up club swimming which she loves and is also a bit worried about the long days, commute, new social circle and rigor. I am curious about the support available at Lville for a pre-med pathway? Do a lot of people pursue 7 year BS/MD programs? Would appreciate any inputs!
