Sunny proves her proficiency in mathematics

SNSD's Sunny has recently become the smartest idol member.

In the episode of KBS 2TV's Invincible Youth 2 that air on March 3, G8 (SNSD's Sunny and Hyoyeon, Miss A's Suzy, SISTAR's Bora, F(X)'s Amber, Rainbow's Woori, Jewely's Ye Won, and KARA's Kang Jiyoung) takes a math test to evaluate their academic abilities.

Test papers are given to the G8 memebers all of sudden, and the mambers take the test, which is an elementary school level.

Unlike other members who get taken aback by the difficult elementary school math, Sunny solves the questions without difficulty.

Also, unlike other members who write full of wrong answers, Sunny gets first place with a matchless score, even solving a fraction question, which is the highest level.
