Interesting quiz! I've been curious about this sort of thing for a while, actually, and was looking through an old linguistics book that had a sample survey--but it didn't say which words came from where, unfortunately.
I test:
70% General American English
15% Upper Midwestern
10% Yankee
0% Dixie
0% Midwestern
(Note: The missing 5% is due to the question on what you call an easy class. I've never called it anything, and have barely even heard of one or two of those terms, so they don't apply.)
My mom grew up in Pennsylvania and my dad grew up in Ohio, more, though he was born in Massachusetts and lived for a time in upstate New York. However, I have not lived east of Illinois since I was 3, and lived in Iowa and Missouri alternately from 6-13. After that I've lived solidly in the Northwest (WA state) for the last 6 years. So that explains the Yankee and Upper Midwestern portions.
