I ain't pass the bar, but I know a little bit

the Bar exam is required for lawyers to legally practice. in context, HOVA is talking to a policeman about his property and search rights; he is telling him that he understands his legal rights and what illegal searches and seizures are
because I chose the career path of rapping and not becoming a lawyer, I didn't take the bar exam which lawyers are required to take before being certified. However, this doesn't mean I'm not intelligent.
