The math exam is just a minor test, not very strict.
The teacher is sitting up front grading papers, not even looking at them, and the people below are copying with great enthusiasm.
Chuzheng props her head up with one hand, holding a pen with the other, writing with an indescribable authority.
Her writing speed doesn't seem fast, but she doesn't pause on any problem.
Although she writes slowly, her reading speed is fast, so on average, her problem-solving speed isn't slow either.
"Xiao Chu, your phone keeps vibrating."
He Shan couldn't hold back anymore, Chuzheng's phone kept vibrating, and if this continued, even the teacher would hear it.
Chuzheng frustratingly put down her pen, glanced at the teacher engrossed in grading on the podium, reached out for her phone, switched it to complete silent mode, and tossed it back in.
He Shan looked at Chuzheng's little maneuver, scratching her head in confusion.
Not going to check who's looking for her?
