I went to SHS 91-94 and I thought I was probably an ignorant redneck mississippi product, but I don't know...
I have gone to grad school and been to programs in private schools like SMU, Duke, Tulsa, and Tulane for different things and I made the same grades, all A's. So, SHS is not the Big-12 of student grades.
Plus, I do not see that the vaunted California, Texas, Mass., and Penn kids are brighter than us hicks. I think people grow up to be idiots for reasons not directly related to schools, more likely upbringing and pop culture. As far as Norman, Oklahoma education, it is completely indistinguishable from Starkville. The the Norman kids are the same lazy, entitled, unskilled, Obama supporting kids that the rest of the country has...including Starkville.
