He is just nine-years-old. He joined Mensa, the high IQ society, when he was four. He enrolled in college at the age of 7 and is already pursuing his degree. Meet the child prodigy and the youngest student of American River College (ARC), Tanishq Abraham.

While children at his age learn the number of planets in the solar system, Abraham wants to learn about the particle physics. He can explain the Higgs Boson, an elusive 'God' particle at this young age.

"I like particle physics and contemplating the fate of the universe," Abraham told the Digital Journal.

He was tested at four years and he received 99.9 percentile on the standardized intelligence test. He joined Mensa which welcomes people whose IQ is in the top 2 per cent with an average adult score of 100.

Abraham had to have home-schooling as he did much better than the fellow students and needed advanced learning skills, a report in the FOX40 News said.

He is currently attending classes in astronomy and paleontology at the ARC in Sacramento, California and is a top student among his college mates.

The child prodigy has given guest lecture to college students on various science related topics. "I don't mind interacting with other college students," Abraham told Fox40 News adding, "I like it".

Abraham joined ARC with the help of Professor Stephen Sterling who was Abraham's physical geology instructor in the college. It was Sterling who helped Tanishq gain enrollment in ARC after meeting him at an earth science class taught by him in 2010.

Apart from attending courses, Abraham is also involved in other extra-curricular activities including playing piano and singing in the Sacramento Boys Chorus.

His little sister Tiara, now 6, is close behind him and also a child genius. Tiara also joined Mensa after achieving 98.8 percentile in the IQ test also at the age of four.
