Mr. Obama graduated from Harvard Law School in 1991, with academic honors.

We can not answer for Mr. Obama.
Barack Obama is a graduate of Columbia University and Harvard Law School.
First, it should be noted that there is no "Barack Obama Jr." His legal name is Barack Obama II. That said, in 1992, Mr. Obama married Michelle Robinson. At that time, he had recently graduated from Harvard Law School and was working as an attorney in a small Chicago firm that specialized in civil rights law.
Mr. Obama is not a certified elementary or high school teacher, so he does not have (nor does he need) these kinds of certifications. However, he did receive his law degree from Harvard University and then received his license to practice law.
Barack Obama moved to Chicago, Illinois in the mid 1980s to work as a community organizer and advocate for the poor. He married a woman from Chicago (Michelle Robinson, today Michelle Obama) and their two daughters were born in Chicago. Mr. Obama taught law at the University of Chicago Law School, and in 1996, was elected to the Illinois State Senate, where he served three terms. He then became a U.S. senator from Illinois prior to being elected president. So Mr. Obama has many ties to Illinois.
She married Mr. Obama.
He had similar experience to some other former presidents: he served in congress, and he worked in the private sector. Mr. Obama also had a background in law and in political science.
Barack Obama has held leadership positions on several occasions during his life. For example, during his years at Harvard Law School, Mr. Obama was chosen as the editor (and leader) of the Harvard Law Review. And in 2008, he was elected to the presidency and thus became the leader of the United States of America.
Mr. Obama was an adjunct professor of law at the University of Chicago Law School for nearly twelve years. He was popular with students, and the school wanted to make him an offer to become full-time faculty, but he decided to go into politics instead.
