Chapter 551 Competition with Classmates
"What are you competing for?" Tang Su looked at Guo Xiangling puzzledly.
"Let's compete in math homework to see who can do it faster and more accurately. Whoever loses will treat us to breakfast tomorrow." Guo Xiangling said with a smile.
She learned this method from Tang Su, who had mentioned this method at a study exchange meeting.
"Okay." Tang Su did not refuse.
Although Guo Xiangling's current academic performance is better than hers, Guo Xiangling ranked 49th in the last final exam, while she ranked 163rd.
Tang Su opened his exercise book and started doing his math homework.
Today's math homework is 5 problem solving questions about statistics and probability.
The workload is still quite large.
Tang Su finished the first three questions relatively quickly, taking only about 15 minutes to finish them.
However, the fourth and fifth questions were a little difficult, and Tang Su spent almost twenty minutes to finish these two questions.
After finishing, she looked at Guo Xiangling and found that she was still answering the fifth question.
"Are you done?" Guo Xiangling saw Tang Su put down his pen.
"Yes." Tang Su replied.
Guo Xiangling continued to do the questions, and about five minutes later, she finished the fifth question.
According to the rules of the competition, if two people have the same accuracy, then whoever takes less time wins. If the accuracy is different, then whoever gets more questions right wins.
After the first evening self-study session, Guo Xiangling went to borrow the exercise book of Liu Yi, the student with the best math grades in the class.
He opened Liu Yi's exercise book and said, "Liu Yi's answer should be the standard answer. Let's start with the questions."
Tang Su nodded.
She also believed that Liu Yi's answer was 99% correct, unless Liu Yi made a careless mistake in the calculation.
The two quickly began to discuss the topic.
Tang Su looked at his answers and found that only the second answer to the fifth question was different from Liu Yi's. The first four questions were exactly the same.
After checking the questions, Guo Xiangling found that her answers were exactly the same as Liu Yi's.
"I lost." After seeing that Guo Xiangling's answer was the same as Liu Yi's, Tang Su directly admitted that he lost.
She didn't think that she was right about question 5, while both Liu Yi and Guo Xiangling were wrong.
The probability of this happening is so small, almost non-existent.
"Then buy me breakfast tomorrow morning." Guo Xiangling smiled happily.
In fact, Tang Su is a pretty nice person, he just doesn't pay much attention to others normally, but he is very nice to his classmates and friends, and he is very loyal.
Last year she injured her foot, and for half a month after evening self-study, Tang Su carried her back to the dormitory.
"What do you want to eat?" Tang Su asked.
Guo Xiangling replied: "Just the same as yours."
Tang Su said yes.
After evening self-study, Tang Su returned to the dormitory to take a shower.
At home, he would spend more than ten minutes in the bath, but at school, she would finish quickly, usually in five or six minutes.
After washing, she also needs to wash her underwear and socks.
As for other clothes, Tang Su usually washes them in the washing machine after getting up in the morning, and then hangs them out to dry at noon.
Other students have to spend a lot of time on their personal affairs, but Tang Su doesn't need to.
After taking a shower, Tang Su lay on the bed to rest.
But she closed her eyes but did not fall asleep.
At this moment she thought of Xue Yao.
Xue Yao hasn't contacted me for more than a month, and hasn't even sent me a message.
Ever since I last proposed to him that we could be friends, he has never contacted me again.
Tang Su didn't know why this happened. She really couldn't guess what Xue Yao was thinking.
