Chapter 285

”Professor, I've finished it.” Cheng Nuo activity activities some sour wrist, will be the finished paper to Liao Zhixing.

”So fast?”

Before Professor Liao spoke, another professor nearby couldn't help but open his mouth, looking very surprised.

”Sit down, sit down. This is the routine operation of Cheng Nuo. Don't make a fuss about it.” Professor Liao gently put the thermos cup in his hand on his desk and said with a happy smile.

For Liao Zhixing, who is familiar with Cheng Nuo, such similar things are not surprising.

As a result, Professor Liao helped his eyes and looked down at the paper carefully.

Two minutes later

Professor Liao put Cheng Nuo's test paper aside, looked up with satisfaction at Cheng Nuo, and gently opened his mouth, ”good, full marks.”

Hearing his full score, Cheng Nuo's expression on his face has no waves.

It's just full marks. It's not a great thing.

He has passed the age when he will be happy with a full score on a test paper!

However, Cheng Nuo is still puzzled. What is Professor Liao doing here? Is it to do a set of test papers with no level to speak of?

”Cough.” Professor Liao coughed gently and pulled Cheng Nuo's mind back.

Professor Liao, with his fingers crossed, leaned forward and asked Cheng Nuo with a kind smile, ”Cheng Nuo, what do you think of the difficulty of the test paper you just made?”

After Professor Liao finished, several other teachers in the office also devoted themselves to Cheng Nuo.

With a little expectation.

Cheng Nuo hesitated for a moment, ”Professor, tell the truth?”

Liao Zhixing laughs: ”it's good to tell the truth and tell what you want to say.”

Cheng Nuo recalled the content of the test paper in his mind. After thinking for a long time, he opened his mouth slowly.

”To be honest, on the whole, the difficulty coefficient of this test paper is too low.”

”Not to mention taking it out as an exam question, even if it is used as a training topic, some people will dislike it.”

Cheng Nuo didn't notice the darkening faces of several professors. He raised a finger and continued to speak.

”First of all, the ten multiple choice questions. The first eight questions can't even be divided into two parts. It's almost as if they are brainless. ”

How to solve the fifth order determinant? Block matrix method? Even if these questions are given to high school students, they won't do wrong! ”

Cheng Nuo raises his second finger.

”And then there are two calculation problems. One is the rank of the matrix, the other is the eigenvector through the eigenvalue? This question... ”

Cheng Nuo has no way to make complaints about it.

”Of the five big questions, the last one is fairly difficult. It is to build a linear equation whose parameters conform to Vandermonde determinant, and use Cramer's rule to reverse the matrix. However, it is too superficial. As long as the formula theorem is listed, it will be solved without brain. ”

Cheng Nuo sighed, ”summing up, that is to say, this set of test papers really don't come out very well. There's nothing new or challenging. ”

”I don't know what the teacher thinks about it. It's a very old age, and there's such a retro topic. The teacher's ideas are quite decadent. ”

”Where are you from, professor?” Cheng Nuo asked with a smile.

Professor Liao's palm trembled slightly and his face was black. ”This is the final exam paper of advanced algebra in mathematics college this year.”

”Aha!”

Cheng Norton was a little confused.
