Grading is a whitepeoplething. They're trying to dumb society down little by little by removing anything that differentiates anyone from anyone. White people have a tendency to categorize, rank, grade, separate, compete, excel and think. All traits that niggers don't or can't do. Frankly, they need to just stop the charade and simply stop any pretense of learning anything other than niggers, niggers, niggers. Don't think. Just comply. That's all they want. Nothing more.
