Super Xueba: Start With A Low Control Score!

Chapter 148 Are These Questions Right? Does it really exist? ? ?

“untie……”

“Combine the equation of l with the elliptic equation.”

“Eliminate y.”

“have to……”

“(1? 9tan2?) x2? 362tan2?? x? 72ta? n? 9? 0? 6tan2?? 6? ab?? tan? x2? x1?? tan?? 22(1? 9tan?) 1? 9tan?.”

“From ab? 2, get tan?? 213,?? tan??, 333????? 5??,?? The range of values ​​is ?0,?????6???6?. ”

“…”

This question is really easy.

As long as you can master the chord length formula and use it flexibly, you can make it almost with your eyes closed.

Such as Jiang Nan.

It took less than half a minute to get it done.

Then……

It took another minute to double check.

after all……

Don’t be afraid of ten thousand, just in case.

Control points 60.

If there is more or less, the points will be deducted. If you make a mistake and fail to reach 60, then you will be overwhelmed.

He was still waiting for the second and third rounds to slap Liu Fan’s face severely, but he couldn’t overturn the boat in the gutter.

“Humph!”

“Annoying Laozi again and again.”

“If you don’t let you know why the flowers are so red.”

“Then am I really a Teenage Mutant Ninja Turtles?”

“A bunch of cripples, wait!”

“…”

It is worth mentioning.

The preliminary Olympiad is usually two and a half hours.

But each round of semifinals is usually three and a half hours.

Although the number of questions is the same, it takes an extra hour, obviously, the difficulty is greatly increased.

but……

Jiang Nan got it done in less than ten minutes.

It’s even checked.

Then he got up and handed in the paper.

The Mathematical Olympiad is different from ordinary exams. There is no saying that the paper cannot be handed in before time.

after all……

If you can’t do it.

You can’t do it no matter how hard you think about it.

Instead of staying in the seat for a few hours, it is better to give up and leave, which can also relieve the pressure of the invigilator.

certainly.

Pay early and leave early.

Although it can relieve the pressure of the invigilator.

But in the eyes of the invigilator.

It is basically hopeless to submit papers in advance.

Just like Jiang Nan.

Good guys!

Others hand in papers in advance.

It only lasted for half an hour, an hour.

But now it takes less than ten minutes to start the exam, Jiang Nan has handed in the paper.

what is this?

Don’t work hard at all, just give up?

It’s too unmotivated!

“This classmate, don’t you know how to do a single question? Give up in less than ten minutes after the test?”

“If you knew this long ago, you shouldn’t have to take the exam, not to mention wasting your city’s quota, it also consumes manpower and material resources.”

“…”

Jiang Nan: “…”

I hand in the paper every time.

The invigilator has to blame himself?

never mind.

You didn’t read my papers, and I didn’t care about you.

“Teacher, I seem to have a bad stomach after eating at noon, and I am not feeling well, and I need to go to the toilet, so…bye.”

Finding an excuse, Jiang Nan directly flashed people.

but……

It’s just fooling the ghost.

In the eyes of the invigilator, Jiang Nan is not good enough, so he won’t be overwhelmed with one question, just playing soy sauce.

Or…

Just want to go to the toilet to smoke.

this……

They are all routines used by students.

but……

By the way, Jiang Nan is really not a routine.

He can smoke or something.

But that thing is harmful to your health. He has smoked it in his previous life, and he hasn’t even touched it in his life.

At the same time.

The moment Jiang Nan left the examination room.

Most of the candidates in the classroom looked up at Jiang Nan, with a hint of surprise in his eyes.

after all……

Qualified to participate in the Olympiad semi-finals.

All are top students from all cities in the province.

Everyone has one goal, that is, to get the ranking, at least it is the second save, and it can add 10 points to the big exam.

so……

No matter how difficult the topic is.

It’s so difficult that they want to cry for their father and mother.

They are also clenching their teeth.

But Jiang Nan handed in the paper less than ten minutes after the test started.

this……

But it is really unprecedented, even if it is placed in the entire Binhai Olympics semi-finals history, it is the first case!

but……

Then they lowered their heads.

Continue to be immersed in the nightmare of problem-solving.

Jiang Nan handing over the paper is Jiang Nan’s business, it has nothing to do with them, just one competitor is missing.

There is only one person who is still staring at Jiang Nan’s far away back, and that is Su Yun from Jiangcheng No. 4 Middle School.

He is the only candidate from Jiangcheng who is assigned to the same examination room as Jiang Nan.

And before the exam.

He also slapped Jiang Nan in public.

nature!

He pays special attention to Jiang Nan.

And left with Jiang Nan handing in the papers.

He had mixed feelings for a while.

How to say?

Should I be happy?

That’s for sure.

After all, Jiang Nan is the opponent he wants to defeat. Now Jiang Nan has abandoned the exam and is eliminated 100% in one round. He can’t advance to the second round. Of course he will be happy.

but……

I am happy.

He also secretly had a trace of admiration in his heart.

Admire Jiang Nan’s courage.

How dare to be in the provincial capital, in the coastal area, and to abandon the exam as soon as it is being watched by so many people?

In fact…

He also sprouted the idea of ​​abandoning the exam.

Just because…

This paper is too difficult.

f*ck!

It’s going to be against the sky!

As early as when he got the paper, the first moment he opened it, he felt very wrong at the first glance.

“Set a={x|x+x-6=0}, b={x|ax+1=0}, if b?a, then a=___2.”

This is the first question.

But why can’t he understand it!

Thinking about it for a long time.

He couldn’t start, had to skip.

He understood the second question.

“The physics and chemistry done by 50 students…it is known…then there are __ people who did both of these experiments right.”

This is the problem of solving cubic equations.

It is not difficult to understand.

But it is not easy to make it.

He tried his best and racked his brains to figure out the answer with difficulty, but he had not had time to be happy.

When he saw the third question.

“Set a?? x|x?? 3 or x? 3?, b?? x|x? 1 or x? 4?, then a? b?___.”

Su Yun: “???”

what?

What the hell is this?

It’s not right, it’s too wrong.

By the way, he had never encountered such a problem before.

There is no solution at all!

Skip again.

Then look at the fourth, fifth, sixth…

All right!

One by one is more difficult, let alone the idea of ​​solving the problem, he can’t even understand the problem, and he just wants to vomit blood.

All of a sudden.

He fell into the deepest level of doubt.

“Are these questions correct?”

“Do these problems really exist?

“Can someone really do such a topic?”

“…”

He is also a schoolmaster anyway, ranking first in Jiangcheng No. 4 Middle School.

In the entire Jiangcheng, although the ranking is a little lower than Liu Fan, Dujiang, Chu Ying Xiaji and Lampuo Mengchuan.

but……

He is also confident that he can compete with those people.

But now…

Look at this paper.

He has the feeling of elementary school students looking at high school questions.

I’m just reading the heavenly book.

A look dumbfounded.

real.

He is about to take the autism test.

Is this Olympiad rematch paper so difficult?

The preliminaries in the city had been difficult enough before. He usually got full marks in math, but he only took more than 70 tests last time.

but now……

Compare with this rematch paper.

The paper for the preliminary round is soeasy!

It’s not on the same level at all.

He was going to be tortured crazy.

Almost subconsciously.

The idea of ​​abandoning the exam came up in his mind.

Only one question is done on one paper, but nothing else is done. What else can you do if you don’t give up the exam?

but……

He immediately suppressed the idea.

You cannot abandon the exam.

He doesn’t have the courage of Jiang Nan.

after all……

So many people watched.

They are all tyrants, and he also wants face.

Moreover, he still carries the hope of the Fourth Middle School. If he abandons the exam, how can he explain to the teacher and the school?

“Jiang Nan, Jiang Nan.”

“You dare to abandon the exam, I admire you very much.”

“But I will never give up the exam anyway. Even if I can’t do it, I will stick to it till the end.”

“There are still more than three hours. Persistence is victory. Even if I get eliminated in one round, I can at least beat you.”

“…”

sp: It’s the weekend, it’s a holiday, I’m going to bed!
