9-12...
I don't think it's possible to be raised and live in the Milwaukee metro with a full "bubble" no matter what your household or class-background was.
I scored a 0-4. However, I think that's the result of answering strictly the "letter of the question."
I used to fish regularly in high school, I just haven't had the time in the past "five" years, so I answered "no."
I have eaten at Applebee's/etc., just not in the "past year" because I don't eat out regularly (it's expensive!), so I answered "no."
Neither me nor my fiancee have served in the military (so I answered no), but both of my grandfathers served enlisted roles in the military and told stories about it as I grew up.
I didn't grow up in a neighborhood where the majority didn't have college degrees (so I answered "no"), but both of my mom's parents came from northern WI farming families, didn't even finish high school, and my grandfather worked as a trucker his whole life.
So, having grown up in the Milwaukee area, I'm having a hard time believing that my score really indicates a "deep cultural isolation within the new upper class bubble."
