Although I haven't figured out what the lottery mechanism of the system is yet, Tao Li feels very happy to be able to help my roommates solve their current troubles. After eating the chicken pot that he longed for, Tao Li went back to the dormitory to rest for a while, and then rushed to school.

After completing the math test, for most people, it is equivalent to completing more than half of the test, after all, even the most difficult mountains have been overturned, and the remaining few small hills, there is nothing to fear.

Jinling Senior High School, Senior 2 Mathematics Teaching and Research Office.

After the students have finished the exam, the task is only half completed for the teacher, and then they still need to mark the papers, register the results, and the more difficult task is actually in the marking part.

"This time, because there are two new colleagues, Xiao Tao and Xiao Li joined, so make adjustments in the distribution of marking tasks, the fill-in-the-blank questions that were originally reviewed by Mr. Wang, this time handed over to Xiao Tao and Xiao Li to mark together, Xiao Li is responsible for the first 7 questions, the remaining 7 questions Xiao Tao is responsible, and the first big question is responsible for correction by Mr. Chen and Mr. Wang...... When reviewing, it is necessary to ensure both speed and quality, and leave the papers in doubt to me for review. ”

The speaker was Yang Zhongming, the leader of the sophomore mathematics teaching and research group.

Marking is a very boring thing, when you are faced with more than 1,000 exam papers, you will know how devastating it is, so generally speaking, the time for the marking teacher to score each question is particularly short, especially the fill-in-the-blank questions, which can be corrected in a few seconds, which is comparable to assembly line production.

In order to ensure the speed of grading, and at the same time to allow Tao Li and Li Jianneng to participate, Yang Zhongming deliberately handed over the fill-in-the-blank questions that were the easiest to correct. After arranging the division of labor, this time the mid-term marking work officially began, every teacher lowered their heads, looking intently at the paper in their hands, the names of the candidates are in the sealed line, so they don't know whose paper they are changing.

For Tao Li, this kind of intensity of marking work is actually not a problem at all, some time ago the correction of homework obtained "B-level marking technology", this time just came in handy, especially the fill-in-the-blank question type of correction, Tao Li didn't even need to look at the answer, directly picked up the pen and began to correct it seriously.

Every time the pen in his hand touches the answer on the answer sheet, Tao Li will subconsciously tick or cross, no need to think about it at all, and Tao Li has also checked, such a correction method, there will be no mistakes!

That's the benefit of the system!

It didn't take half an hour before and after, Tao Li had already finished correcting the papers in 10 examination rooms, and if he continued at this speed, it would take another half an hour for Tao Li to complete all his correction tasks.

"Teacher Tao, how did you change so quickly! I don't see that you didn't look at the answer before! And I always feel like your eyes are not staring at the test paper when you are correcting!"

Li Jianneng, who was sitting opposite him, couldn't help but ask. In the same time, he only corrected the papers in the three examination rooms, less than one-third of the amount of Tao Li's correction, and until now, Li Jianneng has not been able to completely memorize the answers to each question, and in terms of proficiency in correction, he cannot be compared with Tao Li!

This made him wonder very much, why did he lose to Tao Li from his appearance, to the design of the courseware, to the writing of the lesson plan, and even the current grading?

"I have the answer in my heart! I changed it quickly, maybe I corrected a lot of homework some time ago, so I have an experience!" Tao Li finished correcting a paper in his hand, raised his head and said with a smile.

"Teacher Tao, you are so amazing! No wonder so many people like you!" Li Jianneng took the opportunity to pick up a paper that Tao Li had corrected, and said with envy.

"Hey, Mr. Tao, did you correct the last question of the fill-in-the-blank question, the reference answer seems to be 7, why did you cross it?"

Li Jianneng suddenly raised the scroll in his hand and asked.

Tao Li was shocked, and at the same time quickly took the reference answer, it can't be that he really corrected his mistake!

In terms of reference answers, the answer given in question 14 of fill-in-the-blank questions is indeed 7, but why is it wrong when you change it?

Is there a mistake in the system's marking technology?

Or is the reference answer to this question originally wrong?!

"The reference answer gives a solution, but Mr. Tao, you ticked the test paper with two solutions. As he spoke, Li Jianneng handed over another test paper, and the answer written on this paper was "7 or 16", and Tao Li gave points according to the correct answer at that time!

"What's the situation, is there any problem with the answer?" Yang Zhongming, who rushed to hear the news, walked up to Tao Li and asked.

"In the last question of the fill-in-the-blank question, the reference answer should be a missing solution. Although he hadn't done it himself, Tao Li still said confidently.

"How can it be, I have reviewed it several times with Mr. Tian, who produced the paper, and there should be no problem with the answer!" Yang Zhongming also said very firmly.

He has indeed reviewed this answer many times, and the probability of error is extremely low.

The other teachers also put down their work one after another and gathered around at once. After so many years of revision, they are accustomed to giving marks according to the reference answers, and few of them personally verify whether the answers are correct or not.

And it is generally rare for such a reference answer to be wrong, so in this case, they still prefer to believe that Tao Li corrected the error.

"I'll do the math and take a look!" Tao Li didn't say much, took the test paper, read the questions and began to do it.

Yang Zhongming was stunned, and dared to say that this kid had not done it yet, and said that there was a problem with this answer!

When doing the questions, Tao Li likes to keep quiet, especially the finale of this fill-in-the-blank question, which makes his blood surge, and he writes quickly on the scratch paper while thinking.

"It's calculated, it's really two cases, the answer is 7 or 16, and the reference answer doesn't take into account the situation when X is in the range of 0 to 5!"

After five minutes, Tao Li wrote the correct answer to the question.

Yang Zhongming took the problem-solving process handed over by Tao Li and looked at it carefully. It doesn't matter if you look at it, it really let him see some clues!

Yang Zhongming did a lot of calculations, but he didn't expect the implicit conditions in the question, so he missed a solution! What surprised him even more was that even when he did this problem, it took him more than ten minutes, and Tao Li actually only took five minutes to solve the complete process of this problem!

"There is indeed a mistake in the reference answer, Xiao Tao's correction is correct!" Yang Zhongming held the problem-solving process in his hand, and felt a lot of emotion in his heart, but at the same time, he was also glad to leave the last 7 questions of the fill-in-the-blank question to Tao Li for correction, otherwise, I am afraid that it will be a joke.

Hearing Yang Zhongming personally admit that the answer was wrong, the expressions on the faces of those onlookers were very exciting, looking at Tao Li's eyes, just like looking at a monster, the first time he participated in the marking, he could find that the answer was wrong, thinking about the first time he revised the paper that year, he didn't even dare to say much, he just cared about giving points according to the answers, not to mention questioning the reference answers provided by the leader of the preparation team!

"Everyone stops reading the papers in their hands, and everyone checks the reference answers again, and there can be no more mistakes!"

Just in case, Yang Zhongming looked at everyone and said again.
