Wonder Girls’ Yenny revealed the grades she received during her younger years.

Yenny appeared on KBS 2TV’s ‘Happy Together’ and proved herself to be the brain of Wonder Girls. During the show, she said, “I never gave up on studying even though I was busy on promotions. I studied for my university entrance exam even when we released ‘Tell Me’.”

Her high school report card was revealed which showed that she topped in her class. She’d placed first in her class of 41 students, and had placed 9th out of the entire school.

In the same episode, Robert Harley drew viewers’ attention by telling that he got in trouble at airport immigration because he forgot English.
