UC San Diego vs UNC Chapel Hill for Biology/Pre-Med

Net price at each?

Remember, medical school is expensive.

Applying to medical school is also expensive, since it can involve short notice travel to medical school interviews (being closer to your in-state public medical schools and other medical schools you apply to can help).

It is also unlikely from the point of view of a frosh pre-med, since most frosh pre-meds eventually do not apply to medical school, and only 40% of those who do get admitted. So also consider which school is more suitable for you for the case where you do not go to medical school.
