I would say that if you have what it takes to be in Wharton you should apply to Wharton directly. The only way I think you can "try" to apply to both the College and Wharton is through the Huntsman Program. However, tt is far from a guarantee to transfer from the College into Wharton. Like Whartonite1 mentioned, you would need a GPA of at least 3.8 to even be considered.
I've heard Babson College is a good place to study entreprenuership. As for McIntire, it's a two year program that you have to apply to. Thus, you would have to enter UVA and then apply to McIntire.
