How did Abraham Lincoln become a lawyer

Abraham Lincoln, who attended school for less than a year, became a lawyer under an Illinois law enacted in 1833. This law stated that to be a lawyer someone had to "obtain a certificate procured from the court of an Illinois county certifying to the applicant's good moral character." Lincoln actually went to the Illinois Supreme Court to get his certificate. On September 9, 1836, a license to practice law was issued to Abraham Lincoln by two of the justices of the Illinois Supreme Court. Later, in a more formal session, on March 1, 1837, Lincoln appeared before the clerk of the Illinois Supreme Court and took an oath to support the Constitution of the United States and of Illinois. Lincoln swore he would "in all things faithfully execute the duties of Attorney and Counselor at Law." Lincoln was then formally enrolled as an attorney licensed to practice law in all the courts of the state of Illinois.
