At just 14 years of age, Dorothy Jean Tillman of Chicago has become a perfect example of black excellence after she obtained her graduate degree from Unity College in the United States.

Through distant learning, the teen prodigy grabbed her master’s degree in sustainable science and environmental planning.

According to a report by becauseofthemwecan.com, at just 8 months old she began talking, by four she was completing math problems and by nine she was starting high school.

Tillman has always loved learning and once she finished high school, she figured she should pursue her associate's degree which worked in her favour since many of the credits counted towards her bachelors.

She just kept going and at the age of 12, she earned her bachelor’s degree in humanities from Excelsior College.

Before that, Tillman earned her associate’s degree in psychology from the College of Lake County at the age of 10.

With interest in STEM, she went on to pursue a graduate course in sustainable science and environmental planning.

Tillman plans to find ways to give back to other young people looking to pursue a career in STEM.

Addressing her admirable accomplishment, she is quoted as saying that she has ‘‘been working on STEM labs for kids because I really want to go into the STEM-related field and work with kids.’’

She indicated that she might go back to school, but she plans to be an entrepreneur and use her engineering degree.

''I’m not perfect. I’m not the smartest person in the world. It just takes dedication,” she said.
