Chapter 233: , Mathematics teachers who doubt life

　　 Several class teachers in the Chinese opera performance class felt very strange these days!
　　 The class group that was originally lively every day suddenly became quiet recently.
　　 Previously discussed episodes every day, and the students who discussed the performance suddenly disappeared.
　　 They couldn't help but wonder if the students in the class secretly built other groups on their backs.
　　However, after some side-knocking, they found that the students did not regroup.
　　Just when they were puzzled, several math teachers in the acting class found them.
　　 "I suspect students in your class cheated collectively during the math exam."
　　 A mathematics "zero five zero" teacher said very angry.
　　However, without waiting for him to say more, a teacher on the side suddenly chimed in, "Why, is this also the case in your class?"
　　 The math teacher suddenly turned his head and said, "Why? Did the students in your class cheat collectively?"
　　 "Yeah, the average score of our students in this class actually reached 95 points this time. Their average score was only 65 points before. I wouldn’t believe it if they did not cheat."
　　 "Is this also the case in your class? The average math score of our class used to be 70, but this time it suddenly soared to 98 points."
　　 Listening to the words of the two math teachers, the expressions of the two head teachers suddenly became very serious.
　　 Collective cheating. This kind of thing is not a trivial matter in college. If it is really verified, a collective punishment cannot be run away.
　　 It's just that they don't understand why this happens in both classes at the same time, but soon they were relieved again, and the test questions must have been leaked.
"Mr. Li, Mr. Zhang, don't worry. In this way, let's break each one out. You first get a test paper of similar difficulty. Then we find a few students who usually score at the end of the crane to take the exam. Then they will not be denied. Now."
　　 Two math teachers couldn't help but nod together, this is indeed a good way.
　　 They started to act separately. The test papers were very simple. Every time they tested, they would produce several sets of spare papers.
　　 As for the selection of students, it is even simpler. The two head teachers directly called the four students with the lowest mathematics rankings.
　　When eight students came to the department office and heard that they were asked to take the exam again, they instantly understood what was going on.
　　 However, they did not feel how indignant, after all, their previous results were there. This time the results suddenly jumped, and it is normal to be suspected.
　　Understand but understand, but they still hold their breath in their hearts.
　　 Immediately several of them took the paper very seriously.
　　 In this way, two class teachers and two math teachers closely monitored, eight students began to frantically brush up the test papers.
　　 Watching a few people write like this non-stop, the two math teachers couldn't help looking at each other funny.
　　 These students usually don't know what their math grades are like, they are still pretending to be funny.
　　 These students usually don't know what their math grades are like, they are still pretending to be funny.
　　 Immediately they slowly came behind the two students, ready to appreciate the tragic death of these students.
　　However, when they looked at the test papers of these two people seriously, they couldn't help but be stunned.
　　What did they see?
　　 These two usual academic scum actually solved the calculus in a decent way.
　　 "The problem of seeking the limit is the difficulty of this semester, she actually solved it."
　　 "It took him only 4 minutes to solve this function problem. How is this possible?"
　　 At this time, the two class teachers couldn't help but look suspicious, "Did this time the paper was leaked again, otherwise how could they do it so fast?"
　　Although they are not proficient in mathematics, but they will know the answer, they found that the answers written by several people are actually the same, which explains the problem...
　　If they are writing indiscriminately, it is impossible to make such a consistent answer. For a time, they couldn't help but also froze.
　　 It took only forty minutes, and the eight students stopped writing together. It was supposed to take 2 hours of examination papers. They even completed it in only forty minutes.
　　 This made them more and more suspicious.
　　Even if they really have a sudden heartbreak, even if they really change their minds in seconds, this kind of problem-solving speed is too fast?
　　To say that they did not cheat, they couldn't believe it.
　　It's just that they couldn't figure out how these students got the paper.
　　 The two mathematics teachers looked at each other immediately and then came up with a question.
　　 "Since you have learned so solidly, then this question must not be difficult for you."
　　 said that the two math teachers couldn't help but show an expression looking at you.
　　However, several students did not get caught by surprise as he thought of 1.8, but instead bowed their heads and wrote on the paper.
　　After 5 minutes, several people put the pen down again.
　　 Two math teachers hurriedly took over their manuscript paper, and the next second, they could not help but be struck by lightning.
"how is this possible?"
　　 The two head teachers Wen Yan also hurriedly came together, and suddenly saw eight answers, the final result is still completely consistent.
　　 At this moment, they couldn't help Qiqi being speechless.
　　 "Who can tell me what happened?"
　　At this time, the four teachers couldn't help but suspect that they were born. .
