Ning Li finally stopped writing.
"Miss Tan, I'm done."
Tan Kailan's features froze for a split second when she looked at the answers scribbled across the blackboard.
This question was the highlight of the test paper. Pei Song was the only student out of the whole senior form to complete the first two sub-questions.
Not one among them managed to solve the third sub-question.
How did Ning Li do it?!
Cheng Xiangxiang whispered to Ye Ci.
"Lil Ci, she's just writing nonsense right? I heard the class president didn't score full marks because of this question. How could she have possibly solved it?"
Although Cheng Xiangxiang was also in First Class, her results were on the end of the spectrum—especially in mathematics.
She only wrote down the formula underneath this particular question on her test.
Ye Ci wished to nod, but she was stuck halfway through deciphering Ning Li's solution on the blackboard.
