_DESCRIPTION = """
This repository contains the bar exams from the Ordem dos Advogados do Brasil (OAB) in Brazil from 2010 to 2018.
In Brazil, all legal professionals must demonstrate their knowledge of the law and its application by passing the OAB exams, the national bar exams. The OAB exams therefore provide an excellent benchmark for the performance of legal information systems since passing the exam would arguably signal that the system has acquired capacity of legal reasoning comparable to that of a human lawyer.
