The mathematics exam lasted two hours, ending promptly at five o'clock.
When taking the math test, one must be even more serious and careful, because if you don't read carefully, you will misunderstand the questions, which leads to incorrect answers.
Qin Hao was extremely cautious, and it took him about an hour and ten minutes to finish the test paper.
After finishing, he began to check his answers, carefully reviewing each question one by one.
The invigilator in the examination room had noticed him in the morning and nodded slightly when he saw him checking his paper after finishing it.
This must be a good student—his demeanor while taking the test and his patience while checking his answers were giveaways.
The invigilator wondered to himself which school the student was from.
With that thought, he walked over slowly, glanced at Qin Hao, and then continued forward.
Students generally write their name and school on the left side of the answer sheet and test paper.
