I Am the President of the University

"Just kidding, how difficult can it be to test the system developed by Guanghua University?"

"When I get full marks and the Guanghua admissions team begs me to go, I will reject them mercilessly."

With these words on his lips, Zhang Yang snorted and started the test.

After completing the first part of the [Comprehensive Level Evaluation Paper], look at the displayed content above.

He was so angry that he almost vomited blood.

"Damn it, I spent a long time and the result is still not used as a reference?"

"Is your love work in vain?" Zhang Yang said angrily.

Although in the overall level evaluation just now, the higher the score, the harder it gets, but he still despises Guanghua University.

After all, it is difficult to change this deep-rooted consciousness all at once.

"I got 8 questions wrong, damn it!" Zhang Yang looked unhappy. After all, he was also the top student at Double Ten Middle School, and his accuracy rate was only 84%! ! !

But the questions at the end are really difficult.

Before continuing to answer the question, he noticed a line of text.

[The final score is composed of the mathematics part (full score 70) + physics part (full score 10 points) + chemistry part (full score 10 points) + biology part (full score 10 points)]

"Why is it 70 points in mathematics and only 10 points in other physics and chemistry students?" Zhang Yang muttered, but it was okay. Anyway, his results in physics and chemistry were also very good, with perfect scores many times.

Normally, each of the four parts should be worth 25 points, and then the total score is more reasonable.

Looking at the interpretation of Guanghua's score, it seems that mathematics is more important?

But at this time, the sound of "Shua! Shua!" sounded from my ears.

He glanced to the left and right and found that Lu Yan and Yu Mingzhe were already solving equations on scratch paper.

I panicked inside, so I stopped worrying and quickly started answering questions on the [Mathematics Paper].

The ten questions on the first page include true-false questions, multiple-choice questions, and calculation questions. However, for calculation questions, you only need to fill in the answers. As for the calculation process, there is no need.

[1. It is known that the maximum element of the real number set {1, 2, 3, x} is equal to the sum of all elements of the set, then the value of x is ___]

This question is very simple. Zhang Yang did not hesitate and filled in the answer [-3]

Because the condition is equivalent to the sum of the other three numbers in 1, 2, 3 and x except the largest number is 0.

Obviously x\u003c0, so 1+2+x=0, and x=-3.

Look at the second question again.

[2. In the regular triangular pyramid p-abc, ab=1, ap=2, and the plane α passing ab bisects its volume, then the cosine of the angle between the edge pc and the plane α is ____]

"It's not difficult, but you need to make a draft." Zhang Yang pondered for a while, and ideas emerged in his mind.

Pick up the pen and paper on the table and start writing the problem-solving process.

[Suppose the midpoints of ab and pc are k and m respectively, then it is easy to prove that the plane abm is the plane α. It can be known from the midline length formula:

am2=……

So km...(process omitted)=√5/2.

It is also easy to know that the projection of straight line pc on plane α is..., so...

Therefore, the cosine of the angle between edge pc and plane α is 3√5/10 (3 times the root of 5 divided by 10)]

There were five more lines of characters on the draft paper instantly, and it didn't take long, only a minute or two.

Fill in the answers, Zhang Yang adjusts his state, temporarily restrains his contemptuous attitude, and has the confidence to ridicule and get high scores.

As for the following questions, the fastest one took 1 minute, and the slowest one took 4 minutes.

The 10 questions on the first page took a total of 18 minutes.

Zhang Yang breathed a sigh of relief and started answering questions on the second page.

Just after answering the first question on the second page, Zhang Yang's face gradually stiffened.

This question is not easy, and is obviously different in difficulty from the previous ten questions.

The 10 questions on the second page took 25 minutes, 7 minutes longer than before.

When he clicked on the third page and scanned to [Submit Test Paper] at the bottom, Zhang Yang breathed a sigh of relief. This math part was finally over.

When he is a little relaxed, scan to the first question.

"This difficulty..."

Zhang Yang's face was ashen and he was already having a headache.

The questions on the first page are okay, which is the mathematics level of the college entrance examination, but the second page has reached the difficulty of the CMO (China Mathematical Olympiad) semi-finals. The third page... surpasses the CMO, even if it is IMO (International Mathematical Olympiad) The difficulty is not that high either.

"Fortunately, there are only five questions..." Zhang Yang said happily.

If there were ten questions that night, he would definitely not be able to finish them all.

But these five questions alone took him 35 minutes.

The moment I clicked [Submit Test Paper], I just wanted to take a breath, but I noticed that the computer time in the lower right corner was already [16:48].

In other words, there is only 12 minutes left to answer the question...

After the math paper was submitted, the page jumped directly to the [Physics Paper] page, which still had 10 questions.

Zhang Yang looked at the computer page and suddenly became frustrated.

"12 minutes is not enough! What the hell did Guanghua do? There is no time to do so much in 120 minutes. The previous [Comprehensive Proficiency Test Paper] is completely redundant!" Zhang Yang gritted his teeth, completely unconvinced.

120 minutes, even the fastest one in the front takes 15 or 20 minutes.

In the remaining 100 minutes, I have to do [Mathematics Paper], [Physics Paper], [Chemistry Paper] and [Biology Paper], which is exactly one hundred questions.

In other words, one question per minute on average? ? ? ?

Be funny! Who the hell can finish it?

Anyway, he didn't believe that anyone could answer them all in such a short time!

So, when he couldn't help but look aside, he discovered an even more shocking scene...

Zhang Yang asked Lu Yan: "Stone, where have you been?"

Lu Yan gritted his teeth while solving the problem and replied smoothly: "I am doing the [Chemistry Paper], it is really difficult, so difficult!"

Hearing the three words [Chemistry Volume], Zhang Yang fell silent, and then silently looked at his computer. The three big words [Physics Volume] directly above it were particularly dazzling.

"Where did the chemistry paper go?"

"I've just reached the second page, I won't talk anymore, I have to concentrate!"

After Lu Yan answered, he immersed himself in the scratch paper.

Zhang Yang looked at Yu Mingzhe, the smartest of the Three Musketeers of Double Ten Middle School, this time he followed suit and didn't ask first, but poked his head in.

I’m not surprised that the other party wrote [Chemistry Volume], but the page number below is [Page 3]...

It’s almost the last [Biology Volume]!

Then I thought about how I had just finished the [Mathematics Paper] and had not touched a single question on the Physics Paper. I was really screwed.

He has begun to question his IQ. Am I really the fifth best student in the grade?

He was still a little discouraged at first, but when he looked around the computer room, except for the three of them, everyone else's computer interface was still full of math problems.

The entire computer room turned into a zoo, and every student was like a monkey, scratching their heads and ears.

Originally it wasn’t my cup of tea, but the question was too difficult!

This situation is not only happening in Double Ten Middle School, but also in two other key middle schools.

…

Ludao No. 1 Middle School.

Xu Cong looked at the content on the computer screen, his face slightly moved.

From elementary school to high school and then to major competitions, he got perfect scores every time.

He couldn't help but sigh.
