After Chang Kai consumed the power of the system to only 4 units, he left the bathroom with the kitten, and after meeting Zhou Nan, who had been bored for a long time, they swayed back to their respective classrooms.

At this time, the classroom of the second class of the fourth year of high school was already full of people, some people were comparing the answers of the English test, and some people were gossiping about the glorious deeds of biology teacher Chen Guandong.

Of course, the biology teacher in the fourth year of high school has been determined, and it is Chen Guandong Chen, who many people suspect that there is a problem with sexual orientation.

As the bell rang for the fourth class, Chang Kai really saw Teacher Chen walking into the classroom with his hands behind his back.

At least half of the students present had listened to Mr. Chen's class, and they naturally had no doubts about his teaching ability, so they couldn't help but applaud when they saw him enter the classroom.

Teacher Chen immediately clasped his fists on all sides, made a flattered look, and then introduced himself as usual, and then briefly introduced the future course arrangement.

Similar to Mr. Li's arrangement, Mr. Chen is also planning to spend two months to teach the biology textbook first.

This also means that the midterm exam, which will be held in two months' time, will be the first exam in biology class.

After the midterm exams, there is an endless stream of mock exams.

Chang Kai was of course clear about the importance of Mr. Chen's biology class, but he still decisively gave up these two classes.

He knew that the most important thing he should do now was not to review the basics of biology, but to solve the math test in the afternoon perfectly, especially after he learned that Jiang Jinghao had made a big deal about their competition representatives.

Judging from the current shape, Jiang Jinghao is indeed targeting himself, and has made a layout to kick himself out of the second class of high school.

For an enemy like Jiang Jinghao, the most important thing to do is of course to retaliate with a tooth for a tooth!

Maybe I can win the English test I just finished, but the math test in the afternoon is still unknown.

If he overpowers himself in mathematics, he won't be in heaven?

Only by surpassing him in mathematics and English can you mock him and him off!

But this is the next math test

There's no time to think about it, so let's make a set of rolls first!

Chang Kai thought of it, and quickly found a new set of papers from the drawer, and began the fourth journey of mathematics this semester.

Seeing Chang Kai once again start the math paper as if no one was around, his table mate was once again shocked.

Is he stunned or mad?

Is this not crazy and not alive?

Or is it only paranoia that can succeed?

Countless thoughts flashed through Chang Kai's table mate's mind, anyway, he just felt that Chang Kai was a madman!

He gave up English for the sake of mathematics, and now he wants to give up biology!

It's unreasonable!

In fact, how could Chang Kai be fighting alone?

Just when he entered the realm of selflessness, Jiang Jinghao also tacitly took out a math paper and indulged in it.

A lot of people's efforts are just for the sake of the bull B that they bragged about when they were children.

Jiang Jinghao's current efforts are because of his challenge to Chang Kai, but because of the news that spread last night.

He spread the news of the battle between the two, the purpose was quite simple, he just wanted everyone to see clearly, he Jiang Jinghao wanted to trample Chang Kai under his feet, it was just a matter of one sentence.

The reason is that his vanity is still at work, he just wants to win back a little face after failing to confess to Zhou Nan.

But the development of things has long been out of control, and the current shape has become a life-and-death relationship between him and Chang Kai, or even endless!

Although he is absolutely confident of winning, what if?

Now that there are four hours before the math exam, Jiang Jinghao is already in turmoil.

Chang Kai and Jiang Jinghao are both doing math papers together, but the efficiency of their answers is not the same.

Although Jiang Jinghao has been reviewing non-stop these days, the real sense of making papers has only started from last night's self-study class.

The one he's doing now is only the second one.

But Chang Kai has the natural advantage of not being afraid of turning off the lights, and he used the all-night to complete three sets.

Secondly, Chang Kai's IQ has far escaped Jiang Jinghao, and his ability to learn and correct errors is obviously stronger than the latter.

Another one, Chang Kai's temperament is naturally a bit casual, and his face is like "hob meat", the kind that is not afraid of other people's comments when he does something wrong, so he can calmly do what he thinks is right in other classes.

He has the courage to accept criticism, but insists that he will not correct it, he is like a stone in a pit.

This is also the real reason why he quickly entered the realm of no one else.

Jiang Jinghao's self-esteem is stronger and his face is thinner, but his mentality is stuck in the initial stage of caring very much about other people's eyes, so he is also sneaky when he does questions in biology class.

With such a mentality, how can he achieve the purpose of exercising himself?

Until the bell of the last class rang suddenly, Jiang Jinghao, who had racked his brains for more than 90 minutes, only scored more than 80 points after completing the paper.

At the same time, Chang Kai finished the entire volume.

After the bell rang, Teacher Chen left the classroom with his hands behind his back, and the students in the class left the classroom in groups of three or five laughing, ready to go back to the dormitory to get the guys who eat, and then go to the cafeteria to line up for food.

There were also some foodies who took out the rice bowl directly from the drawer and rushed to the cafeteria at a speed beyond ordinary people.

When people who don't know the truth see this, they can't help but complain silently, "You don't need to work hard to study, you can eat and charge!" ”

Of course, if the person who charges with a rice bowl hears such a complaint, he will definitely refute it like this, "I am not active in eating, and I have a problem with my brain!" ”

From another point of view, why don't these students who run to eat come back to study earlier?

Starting from saving time, what they do is really nothing to complain about!

Of course, Chang Kai thought about eating in the school cafeteria, because it would squeeze out more study time.

The problem is that the food in the school cafeteria is so poor that a meal at school will reduce the electricity of a few units, which is really more than worth the loss!

Moreover, if you want to eat in the school cafeteria, you have to buy a rice bowl first.

Where to eat after eating is also a problem, and where to wash the rice bowl after eating is also a problem

Anyway, it will be troublesome for dormitory students to eat at school.

When Chang Kai watched Zhou Nan stand up, he immediately beckoned to her, "You wait for me for a few minutes, let's go to dinner later, right?" ”

Zhou Nan smiled and nodded, and after leaving his seat, he sat directly on the seat of his tablemate.

Chang Kai asked her to wait for herself, firstly, because it was the peak season for eating, and it would be a waste of time to queue up to eat; Another is that he wants to know how many points he can get for the paper he just made earlier.

Of course, confirming the score is not the most important thing, what he needs to do most is actually the next check and fill in the gaps.

Checking and filling in the gaps is the most urgent thing to solve after the exam, and it is also the foundation for his progress.
