Chapter 589： No one can do all the questions!

"Just kidding, how difficult can the test system made by Guanghua University be?"

"When I get a full score, and then the Guanghua admissions team begs me to go, I will reject them severely."

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

Look at the above display until the first part of the [Comprehensive Level Evaluation Paper] is completed.

He almost vomited blood.

"Uncle's, after tossing for a long time, the result is not used as a reference??"

"Is this a waste of love?" Zhang Yang said angrily.

Although in the comprehensive level evaluation just now, the more difficult it is, he still despised Guanghua University.

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

"I got 8 questions wrong, **** it!" Zhang Yang's face is not very good-looking, after all, he is also a top student in Double Ten Middle School, and the accuracy rate is only 84%! ! !

But the next question is really difficult.

Before starting to answer the question, he noticed a line of words.

[The final score is composed of Maths (out of 70) + Physics (out of 10) + Chemistry (out of 10) + Biology (out of 10)]

"Why is it 70 in math and only 10 in other physical and chemical students?" Zhang Yang muttered, but it was okay. Anyway, his physical and chemical students' grades were also very good, and he scored full marks many times.

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

Looking at the interpretation of Guanghua's scores, it seems that he values ​​mathematics more?

But at this time, the voice of "Shu! Shu!" sounded from the ear.

He glanced to the left and right, and found that Lu Yan and Yu Mingzhe had already solved the equations on the scratch paper.

When I panicked, I stopped grumbling, and quickly started answering the [Mathematics Paper].

On the first page, there are ten-question judgment questions, multiple-choice questions, and calculation questions, but the calculation questions only need to fill in the answer, and the calculation process is exempted.

[1. The largest element of the known 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 he filled in [-3] in the answer.

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

obviously x

Look at the second question.

[2. In the regular triangular pyramid P-ABC, AB=1, AP=2, and the plane α passing through AB bisects its volume, then the cosine value of the angle formed by the edge PC and the plane α is ____]

"It's not difficult, but I 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.

[Assuming that 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, and it can be known from the formula of the midline length:

AM=…

So KM...(the process is omitted)=√5/2.

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

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

There were 5 more lines of characters on the scratch paper in an instant, and it didn't take long, only a minute or two.

Fill in the answer, Zhang Yang adjusts his state, and his contempt mentality is temporarily restrained. If you want to ridicule, you have to get a high score to have confidence.

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

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

Zhang Yang breathed a sigh of relief and began to answer the 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 very simple, and it is obviously different from the previous ten questions in difficulty.

The 10 questions on the second page were delayed by 25 minutes, 7 minutes more than the previous one.

When I clicked on the third page, I swiped to the bottom of the [Submit Test Paper], Zhang Yang breathed a sigh of relief, and finally ended this math part.

When he was a little relaxed, he swept to the first question again.

"This difficulty..."

Zhang Yang's face was ashen, and he had already started to have a headache.

The topic on the first page is okay, that is, the mathematics level of the college entrance examination, but the second page has reached the difficulty of the CMO (China Mathematical Olympiad) rematch. This third page... surpasses the CMO, even if it is the IMO (International Mathematical Olympiad) The difficulty is not that high.

"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 it.

But these five questions alone cost 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 are only 12 minutes left to answer the question...

After the math paper is submitted, the page jumps directly to the [Physical Volume] page, which is still 10 questions.

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

"How can 12 minutes be enough! What kind of **** did Guanghua get? 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 dissatisfied.

120 minutes, even if the fastest in the front is 15 or 20 minutes.

In the remaining 100 minutes, there are exactly one hundred questions to do [Mathematics Paper], [Physics Paper], [Chemistry Paper] and [Biology Paper].

That is, on average, one question per minute? ? ? ?

Be funny! Who can finish it?

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

So, when he couldn't help but look to the side again, he found an even more shocking scene...

Zhang Yang asked Lu Yan, "Stone, what did you do?"

Lu Yan gritted his teeth while solving the problem and replied: "I'm doing the [Chemistry Paper], it's really hard, it's hard to do!"

Hearing the three words [Chemistry Volume], Zhang Yang was silent, and then silently glanced at his computer, the three words [Physics Volume] above it were particularly dazzling.

"Where did the chemistry roll do?"

"Just finished the second page, let's not talk, I have to concentrate!"

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

Zhang Yang looked at Yu Mingzhe, the smartest of the Three Musketeers in Double Ten Middle School.

It is not surprising that the other party wrote [Chemical Volume], but the number of pages below is [Page 3]...

This is almost the final [Biology Scroll]!

Then I thought that I had just finished the [Mathematics Paper], and the physics paper had not moved a single question, it was really **** up.

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

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

The entire computer room was turned into a zoo, and all the students were scratching their ears like monkeys.

Originally it wasn't my dish, but this topic was too difficult!

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

...

Ludao No. 1 Middle School.

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

From elementary school to high school to major competitions, he is almost a full score every time.

He couldn't help but sigh.

(Ask for a monthly pass!)
