"This is the test paper of this term of the junior high school unified examination, and there is no standard answer yet."

"I heard from your teacher Ji that you can even pass the test papers of the college entrance examination, and the test papers of junior high school should not be a problem, right?"

Liang Sining asked, with undisguised suspicion in his eyes:

"Do the five-year college entrance examination three-year mock test papers, I suspect you may have memorized the standard answers in advance."

"If you can make this test paper and take my classes in the future, you can do whatever you want."

"How's that, can you make it?"

Can you?

Gu Xiu smiled.

I didn't say anything, just picked up the pen and started to work on the test paper.

If you can't do the exam paper in the third year of junior high school, then what should you do to learn God?

In fact, even if Gu Xiu is a reborn person, a lot of knowledge has actually been forgotten, and if he gets this test paper for no reason, it is really possible to be blind.

After all, it has been a few years since I graduated from the college entrance examination, and I have almost forgotten my high school knowledge.

Not to mention junior high school knowledge.

Even if he has an excellent memory, it is impossible to enhance Gu Xiu's ability to brush questions.

So, in fact, he really didn't lie before.

When he was idle and bored, he had actually been teaching himself junior high and high school knowledge.

The difference though.

Others think he is pre-learning knowledge, but in fact, it is just a review for him.

Many types of questions, as long as you do them once, you can immediately re-grasp them, especially after memory enhancement, and even some knowledge points that are often confused in previous lives.

In this life, there is no problem at all.

Naturally, the math test paper of the third year of junior high school in front of him was not too simple for Gu Xiu.

Even, he deliberately forced himself not to use the knowledge points of college and high school to complete the answer.

But even so.

He's still fast.

Originally, Liang Sining, after seeing Gu Xiu start to do the test papers, turned around and went to the kitchen to cook.

But what he didn't expect was this.

Just after choosing the dish, before he started to put it in the pot, Gu Xiu was already holding the test paper:

"Teacher Liang, I've done a good job."

"Done?"

"Well, it's all done, but the answer question paper is a little insufficient, so I wrote it in this draft book."

Liang Sining was stunned, looked at the other draft book that Gu Xiu was holding, and sure enough, he saw the answers to several test questions on it.

Glancing at the time, Liang Sining couldn't help frowning:

"It only took you fifteen minutes to do it? Checked? ”

"It's been checked." Gu Xiu nodded.

At this moment, Liang Sining was a little surprised, and glanced at Gu Xiu strangely, but hesitated, and didn't say anything, just wiped the water stains on his hands.

I picked up the test paper and read it.

At this look, Liang Sining's expression froze.

Multiple choice questions, all right!

Fill-in-the-blank questions, all right!

Answer the question......

It's all right!!

This test paper is a city-wide mid-term exam paper, and many of the math questions are difficult problems.

The average middle school student can finish it in an hour and a half, which is good, but the elementary school student in front of him only took fifteen minutes!

It's all right!

This...... He wouldn't know the standard answer, would he?

But soon, Liang Sining shook his head, the middle school students in the third year of this test paper had just finished the exam, and many of them hadn't even gotten their results yet.

There is simply no possible detailed answer!

This kid ...... What the hell?

Liang Sining glanced at Gu Xiu, although he was extremely shocked in his heart, but after all, he was an old teacher, so naturally he would not be easily seen by others.

At this time, I took a closer look at the solution methods of the next few questions, and Liang Sining wanted to let the kid in front of him not be too arrogant:

"The last question, your idea is not bad, but there is actually an easier way to solve the problem, do you know?"

Unexpectedly, Gu Xiu actually nodded: "I know." ”

"Know?" Liang Sining frowned: "Young people can't talk nonsense, if you know, why don't you use it?" ”

"This is a junior high school test paper, and I also use the knowledge points of junior high school, in fact, if this question is solved by the formula of high school, it will be easier and simpler."

Gu Xiu replied with a slight smile.

And Liang Sining froze in place, he didn't expect that this kid would deliberately use junior high school knowledge to answer questions.

But he couldn't doubt it, so he saw that Gu Xiu had already opened the draft book, and sure enough, on the back page, he had already written out the answer method of using high school knowledge to answer.

And, it's pretty standard!

Although he only uses the foundation of high school knowledge points, it can be seen from Gu Xiu's problem-solving ideas that this child's thinking is very clear and his purpose is also very clear.

This can only say one thing.

At least, the high school knowledge point used by Gu Xiu is really integrated!

This discovery did not make Liang Sining feel frustrated, on the contrary, his heart was hot at this time, and even a smile appeared on his face:

"I heard that you have already learned high school knowledge on your own, tell me how much you have learned?"

"In fact, I have almost learned the knowledge of high school, and the knowledge points of science have been completed by myself." Gu Xiu blinked:

"In math, I'm teaching myself calculus at the moment."

"Ahem......!"

Liang Sining was choked, and the whole person coughed violently, but he still endured the discomfort in his throat and asked in a somewhat weird voice:

"Calculus? Isn't that college knowledge? ”

"Although many of the knowledge points in high school are interesting, I feel that advanced mathematics is more useful and convenient, so I learned it in advance."

This......

Liang Sining was dumbfounded, and was a little speechless for a while.

His eyes were staring at Gu Xiu, extremely serious, as if he wanted to see the lack of confidence and the evidence of lying in the eyes of the child in front of him.

But it's a pity that Gu Xiu only has plainness and confidence in his eyes, and there is no cowardice at all.

He didn't lie!

What he said is true, and it is even possible that he has some reservations about what he said!

This idea popped up in his mind, and even Liang Sining felt outrageous.

After all, higher mathematics is not that simple.

This is not something that can be easily learned by simply reading a book.

Because in fact, the things in the high math textbooks are all jumpy, and there is no one to guide them, so it is impossible to learn them by reading the textbook.

Even many people will only feel confused when they read the textbook.

Even if it's a college student.

It is also rare to be able to directly learn the knowledge points that you have not learned by yourself through the textbook.

How could this seven-year-old do it?

"I don't care about high math or anything for the time being, since you said that you learned math in high school, then do this test paper." Liang Sining thought about it and took out another test paper.

This test paper is also a unified examination paper.

But the difference is that this test paper is a math test paper for the third year of high school!

As before, Gu Xiu didn't say anything, just took the test paper, sat down in his seat, and directly began to read the answers.

This time, Liang Sining didn't cook anymore.

He moved a stool and sat beside Gu Xiu, his eyes always staring at Gu Xiu.

He wanted to see how this kid did it.

But this looks.

But it made him sure of something unbelievable.

The seven-year-old ......

Really, it's a demon!
