Home-schooled since the age of 7, Abraham passed a state exam in March that certified he had met the appropriate academic standards to receive his diploma.
"It wasn't easy because of the bureaucracy, but I have put a lot of hard work into this and I am very happy that I am finally graduating high school," Abraham, who has presidential ambitions, told ABC News.
Abraham is powering ahead, scoring well on the SATs and finishing up the community college classes he has been taking since he was 7-years-old.
"I am going to finish my community college by almost next semester and then I will have my associate's degree, after that I will transfer to university," he was quoted as saying after becoming one of the youngest ever to graduate high school in the US.
Abraham said he would like to transfer to UC Davis to study medicine. In kindergarten, Abraham said, he realised he had a special gift.
"I could read books that were meant for second and third graders, I was also able to do math like second and third graders," Abraham said.
"My ultimate goal would be science, like scientist or doctor, but also want to be president too," he said.
