I’m confused. I can’t find that the Kean BS/MD exists. Maybe you mean the 5 year BS/MS program?
Some things to consider–if your D does decide to pursue a PhD in a STEM field, grad positions are almost always funded. Your D will be get tuition remission + a living expenses stipend (typically around $22-25K/year). So you don’t need to worry about paying for grad school.
Paying for med school is a whole other story. But 75% of freshmen pre-meds change their mind about med school and never apply, so picking the cheapest/free option for undergrad in order to save for med school isn’t necessarily a wise decision.
Drexel & Lehigh have very different atmospheres. Drexel has a rather gritty, diffuse urban campus and nearly all students participate in co-op; Lehigh has a more traditional campus and offers a more traditional 4 year academic experience.
This is your D’s future. The decisions about which college to attend is really hers. You should have the “finances” talk with her. Give her a budget of how much you’re willing to spend on college. Then she gets to choose. If she chooses a free or low cost option, then she gets any leftover funds to apply toward something else, like a semester/year of study abroad or help funding professional school.
