It reminded her of a question a classmate had asked Fifth Sister. That classmate had asked why Fifth Sister always scored the same as she did. At that time, Fifth Sister replied, "That's because I know which questions Fourth Sister can't answer. Other than those questions she does not know the answers to, she would have answered everything else correctly."
Su Xue had not thought much about what Fifth Sister had said. In hindsight, she should have known what Fifth Sister had been trying to say. Indeed, her hubris blinded her to her sister's capabilities.
It was obvious that Fifth Sister was accommodating her!
"Su Xue, what are you doing here? The exams are about to start. You've been assigned to exam hall one. Come on!" Cao Jun waved at Su Xue enthusiastically, exuding a youthful vitality that made him shine like the first rays of dawn.
So vivacious was he that Su Xue could even see the sweat on his brow.
