After sending the three children to the examination room, Principal Chen waited nervously.
The exam time was 2.5 hours, from 9 am to 11:30 am.
However, he didn't wait outside the examination room all the time, instead, he went to a friend's tea shop for some tea.
Seeing his arrival, Principal Chen's close friend, Zhou Cheng, teased, "You're a busy man, what brings you here today? This is a rare occasion!"
Principal Chen laughed and replied, "I brought a few students here for an exam today!"
Zhou Cheng curiously asked, "Exam? What kind of exam would require the principal himself to lead the team? Aren't other teachers responsible for those previous exams and competitions?"
Of course, Principal Chen couldn't tell him the truth, so he said, "Well, all the other teachers are occupied, so I'm the one who brought the kids to take the test."
Zhou Cheng nodded and said, "Enough talking, let's have some tea. How long will the kids take for the exam?"
