A perfect test paper, low, medium and high difficulty questions should be interspersed with each other, which not only plays a role in selecting talents, but also does not make most students lose the joy of learning.

To ensure that more than 50% of the juniors and sisters pass, the proportion of medium and low difficulty questions is set at 70%.

The remaining 30% of the difficult questions are reserved for math geniuses, which is the basic operation.

Shen Qi's heart is still soft, and the test papers given to him by Sun Erxiong have more than 70% of the difficult test questions.

Shen Qi set up ten questions, 5 fill-in-the-blank questions, and 5 answer proof questions.

On the last day before New Year's Day, Shen Qi handed over the finished test paper to Sun Erxiong.

Sun Erxiong jumped up after reading the test paper: "Shen Qi, this is just the final exam paper for freshman students, not the selection of outstanding young people!"

"Professor Sun, do you mean that my question is too difficult?" Shen Qi asked tentatively.

"Shen Qi, you are only suitable for research, not for being a teacher and bringing newcomers. Sun Erxiong said, "If the newcomer follows you, he will go crazy in less than two months." ”

Shen Qi was quite innocent: "This ...... I have lowered the overall difficulty of this senior generation test paper to the ordinary level. In fact, this is the second version of the product, and the difficulty of the first version is nightmare level, so I think it is inappropriate, so I adjusted it to the ordinary level. ”

"This is your logic!" Sun Erxiong glanced at Shen Qi, "Let's just say that the last problem you came up with, the Grassmann inner product of three-dimensional supercomplex numbers, the product of two vectors of Hamiltonian quaternions, find the determinant expression, quaternion and vectors This is not difficult, but the problem-solving point you set is the Laplace operator...... I didn't even talk about it here!"

"Then Professor Sun, your teaching progress is too slow, I remember when we were freshmen, you talked about it a long time ago. ”

"You're all gifted kids...... Come on, Shen Tiancai, please go back, it's none of your business here, and in the end, I still have to revise the test papers. Sun Erxiong said.

"All changes?" Shen Qi was a little depressed, the hard work of the past few days was in vain.

"You don't have to change it all, just keep half of your questions. At least the penultimate problem is a proof question, your setting idea is very ingenious, Jacobian theorem has been used by you, and it takes a few turns to complete the proof, but it is not beyond the outline, this is a brain-burning problem, and the burning is just right. Sun Erxiong expressed his satisfaction and appreciation for Shen Qi's few questions.

After New Year's Day, good news came one after another.

Shen Qi finally got a full score this semester, and the two physics courses of "Methods of Mathematical Physics" and "Fundamentals of Cosmic Physics" were both 100 points.

Shen Qi has already received half of the credits in the second major of physics, and the average score has returned to about 99.

The paper "A Class of Bounded Analysis of Strong Singular Integral Operators along Homogeneous Curves" took more than half a year to finally be published in the English edition of Acta Mathematica Sinica, Series B.

Affectionately stroking the sample journal, Shen Qi felt happy, this is the seventh paper he published after studying in college, the second SCI.

Congratulations to the host for publishing a SCI math paper, the basic reward is 15,000 Xueba points, multiplied by the math master talent coefficient of 2.0, and the final reward is 30,000 Xueba points, please confirm with the host. ”

"In less than two academic years after the host entered the university, he has published a total of seven papers, activating the new achievement task 'Diligent Writing Essay Award'. If the host publishes a total of 10 papers in two academic years, they will be rewarded with special tasks. ”

"The reward for the achievement task of the 'Diligent Writing Essay Award' is: 1. The basic reward of 100,000 points of Xueba points will be issued at one time on the day the task is completed. If all 10 papers are math papers, you can enjoy a 2.0x bonus to the main talent;

2. From now on the completion of the task, a new indicator of diligent writing papers will be opened, if the host publishes no less than 5 papers every two years, each paper will be multiplied by the impact factor on the basic reward value of the Xueba points (if it is a mathematical paper, it can be superimposed by 2.0 times the main talent bonus), and the resulting value is the final reward value. If the journal impact factor of the published paper is less than 1, it will be calculated as 1. ”

Three semesters, less than two years, seven papers, Shen Qi is indeed very diligent. Most students don't have enough papers until they graduate from graduate school.

The system has released a new task, and if Shen Qi can collect ten papers by September this year, he will receive a special reward.

The hero sees the same thing, Shen Qi coincides with the system, and the goal he set for himself before is to publish 10 papers before going abroad.

The special mission rewards are very attractive, and the first reward is a one-time distribution of 100,000 Xueba points.

For Shen Qi, it is actually 200,000 points of academic mastery, and he must have to gather ten math papers, and make reasonable use of the rules.

The second reward is a bigger benefit, although most mathematics journals have an IF of less than 1, there are always a few math journals with an IF of more than 1.

By publishing papers to obtain Xueba points, the system actually gives Shen Qi a new integral coefficient, that is, IF.

After special treatment by the system, this coefficient ≥ 1.

This made Shen Qi very excited, and he couldn't even sleep with excitement.

It is true that Ann-Math, the world's best mathematics journal, does not have an impact factor of more than 5, hovering between 3~4.

On the contrary, for those comprehensive journals that serve the general reader, the IF can easily exceed 5 or even more than 10.

The IF of Nature and Science has been above 30 for a long time, with an average of around 40 and occasionally more than 50.

If you publish a paper in Nature or Science, the basic reward value is 15,000 points, multiplied by IF=40...... It's exciting!

However, Nature and Science almost never accept mathematics papers, so Shen Qi is glad that he chose physics as his second major.

Of course, this is a matter for the future, and it is a long-term plan.

It is imperative to complete the special achievement task first and gather ten papers as soon as possible.

Fortunately, Shen Qi had already prepared, and the topic paper could basically be set as the 8th.

On January 5, Shen Qi was arranged by Sun Erxiong as an invigilator and was responsible for the examination discipline in an examination room.

This exam room is a first-year student in the Department of Mathematics, and today's final exam subject is "Advanced Algebra".

The freshman math department has two classes, and the total number of students is twice that of the sophomore math department.

As the total number of girls increases, so does the number of girls.

There are five girls in the freshman mathematics department, which is gratifying.

Shen Qi walked in the examination room, observing the every move of the junior brothers and sisters.

Shen Qi also saw the final version of the Gao Dai test paper just now.

There are a total of ten questions in this exam paper, five of which were written by Shen Qi, and the other five questions were changed by Sun Erxiong, and the difficulty was significantly reduced.

Shen Qi gently paced behind a girl and secretly observed.

This first-year math girl has a hairstyle that is highly similar to Ouye's, with long black and straight hair, and her hair is relatively smooth.

But the mathematical level of Hei Zhichang No. 2 is worse than that of Hei Zhichang No. 1 by more than eight streets, and Ou Ye in the same period can beat the girl of Hei Zhichang No. 2.

"Can't do the simplest fill-in-the-blank question?" Shen Qi looked anxious, this girl's mind was not on mathematics. Ou Ye went to the examination room during his freshman year, and Ji Ji was able to get the correct answer by virtue of mental arithmetic.
