Hardcore

Lately I have seen more and more people wearing "School of Hard Knocks" shirts, some even with numbers on them, which never ceases to amuse me. I wonder how one can gain admissions into such a prestigious school, aka the Harvard of the Ghettos. How are these guys doing in "school"? What are their GPAs? Do they avoid hard classes like Honors Pimping or AP Drive By in order to boost their GPAs? Do they have to pass some kind of graduation test? Are there tutors to help them if they are not dealing up to their potential?
