Both schools offer the required pre-med classes. Quality of the teaching will vary from instructor to instructor even at the same school–so that’s not a useful discussion point.
Both schools offer research opportunities. It’s up to you to find them. UDub has more lab positions, but then again UDub has lots more students seeking those positions too.
UDub has adjacent med school–but it’s tough to get a volunteer position there due to the sheer number of students; Villanova doesn’t have med school, but there are a number of hospitals in Radnor/Main Line area. (You may need a car, though. IIRC, there are no hospitals within walking distance of Villanova’s campus. Can’t remember if there are any within walking distance from train stops.) But then again, there are places other than hospitals that present opportunities for clinical volunteering at both locations.
UDub offers a wider selection of courses in neuro than does VIllanova. (D1 did a summer research fellowship at UDub in neuro and said she was envious of the sheer variety of the offerings. She attended a mid-sized top research U that has a national reputation in neuro.) But that’s the difference between a big school and smaller school. There may be other factors the make a smaller school–like greater contact with faculty members–more attractive.
UW has a stronger reputation in neuroscience/neurobiology than does Villanova, but if you’re not intending to pursue graduate studies, the point is moot.
No school will prepare you for the MCAT. Preparation is on you.
Both schools will offer a you a great education. Really college is what you make of it. Choose the one that’s best for you.
If you have specific questions about the campus or specific opportunities on campus, you might ask on the UW and Villanova specific forums.
