Ekeh was born in Nigeria and came to the United States when he was eight. He wrote his main college essay about the struggle to adjust, including being clueless in U.S. history classes at school. He said he would ask his parents repeatedly why they moved.

Mr. Ekeh said:
“I came over with a very heavy Nigerian accent, but I did everything I could to integrate. Learning American history was really hard but I was determined to tackle it so I signed up for AP History as a junior.”
Appears to be an exceptional young man, properly acknowledged and rewarded. Congratulations - good on him.
