mmm..i wouldnt say easier..but it is an advantage because all of your resources are within your reach...my undergrad does not have a medical school but there is one like around the corner and is affiliated with us...so i take advantage of those people as much as possible. I shadowed doctors there, i spoke to admissions there, i have worked there..the opportunities are endless..
Yeah, I'd agree that there are some mixed opinions about this. But generally what I heard was that some universities would rather you explore some other options/places rather than just sticking with the familiar, so to speak.
