Start as a top student and move towards the stars and the sea

After all, Ning Chen had just experienced several hours of intense study, and the energy consumption was undoubtedly very huge.

This made Ning Chen fall into a deep sleep quickly.

…

Time passed day by day, and Ning Chen gradually mastered the way to enter the flow state.

As long as he discards all external interference and allows himself to focus on what he is doing, Ning Chen will naturally enter a state of flow.

After a certain period of training, even if the surrounding environment is not so quiet, it will not affect Ning Chen's study.

Of course, the flow state cannot be entered indefinitely. Once Ning Chen's energy drops seriously, he will not be able to maintain his full concentration.

Therefore, Ning Chen must combine work and rest so that he can enter more of a flow state.

Calculated in this way, although Ning Chen's daily study time is not too exaggerated, he can always maintain high learning efficiency. The learning effect is much better than burning the midnight oil to read.

In a week's spare time, Ning Chen has completely mastered all the knowledge points of Advanced Mathematics (Part 1) and has completed most of the questions in the book.

Although this speed is not particularly fast, for Ning Chen, it is already very efficient.

In the advanced mathematics class that day, the advanced mathematics teacher He Sheng was explaining the course on Lópida's Law.

When we use L'Hôpital's law, we should simplify the function as much as possible, pay attention to using equivalent infinitesimals, and isolate factors with non-zero limits.

Using equivalent infinitesimal substitution, the complex function product factors are replaced with equivalent power functions.

“If the limit lim f’(x)/g’(x) does not exist, then Lópida’s law fails...

Ning Chen had already mastered this knowledge very well, so he did not attend the lectures, but just studied the questions on his own.

It was difficult for Ning Chen to enter the flow state while listening to the lecture, let alone the content that Ning Chen had already studied by himself. Self-study was naturally a better choice for Ning Chen.

During the break in the big class, a few students sneaked out of the classroom with their schoolbags, because the teacher had already called their names in the first period, which meant that it was very safe to skip class in the next period.

But what they don't know is that this little trick can't be hidden from the teacher's eyes.

There are thirty minutes left. I won't lecture anymore. We will take a short test. This test will be included in the usual score. Students who have completed the test can leave directly after handing in the paper without waiting until the end of get out of class.

As he spoke, He Sheng closed the classroom door, found a few questions on the computer, and projected them on the big screen.

Hearing He Sheng's words, the students in the classroom couldn't help but sigh.

Fortunately, I didn't skip class this time, otherwise my usual score would have been reduced by five points.

It's too late to inform those students who skipped classes now. Teacher He has already closed the door. Obviously he doesn't want the students who skipped classes to come back.

And if you hand over a paper and take away one person, you won't be able to answer questions for others. Teacher He really has a way.

After everyone whispered for a few words, they all focused on the big screen.

After all, a quiz is different from a simple roll call. You can only get points if you answer correctly.

Hearing that a short test was about to take place, Ning Chen also stopped answering questions and raised his head to look at the big screen.

Ning Chen remembered that in his previous life, he had fallen into this trap for skipping classes, and had been deducted five points from his usual score.

At that time, Ning Chen also complained about the insidiousness of the mathematics teacher, but after all, this was the power exercised by university teachers under their own responsibilities, and it was understandable.

After glancing at the questions of the quiz, Ning Chen didn't feel any pressure.

These are the types of questions that Ning Chen has already done. They just changed the questions slightly. Ning Chen can solve these questions easily.

After tearing off a piece of paper, Ning Chen quickly answered.

After projecting the question on the big screen, He Sheng was not idle, walking back and forth in the classroom aisle.

For this kind of small test-level exam, the proctoring will definitely not be very strict, but He Sheng doesn't want everyone to plagiarize from each other casually.

These questions are all composed by He Sheng himself, and they are all calculation questions and solution questions, which also maximizes the difficulty for students to plagiarize from each other.

The overall difficulty of these questions is not very high, but because this small test was a bit sudden, many students were not prepared, either secretly flipping through the textbooks, or squinting at the classmates next to them.

Ning Chen kept his head down and answered the questions without hesitation, without any pause at all.

The first question can be solved by first dividing it into 0/0 type unfinished formulas, and then using equivalent infinitesimals and L'Hôpital's law.

For the second question, first perform a trigonometric transformation to eliminate sinx-sinα, and then use L'Horbid's rule.

The third question has a slight change, it is a 0·∞ type, but as long as it is transformed a little bit...

Chen Tianpeng, who was sitting next to Ning Chen, couldn't help but marveled as he watched Ning Chen quickly answer the questions on the big screen.

As expected of a top student who hangs out in the library when he first enters college. He's just different from scumbag students like us.

When Ning Chen had finished three questions, Chen Tianpeng had just found the idea for the first question through the example questions in the textbook, but he had not yet started writing.

Fortunately, there was such a big boss sitting next to him. Chen Tianpeng simply gave up answering the questions by himself and directly copied Ning Chen's answer.

But after all, He Sheng had been patrolling back and forth, and Chen Tianpeng couldn't copy it too obviously, so he could only minimize his movements.

In less than ten minutes, Ning Chen finished all the questions.

Ning Chen wrote his name and student number on the paper, and then picked up the paper and school bag to hand in the paper.

After all, the teacher had already said that class could end early after handing in the papers. Ning Chen didn't want to waste time in the classroom and had to go to the library early to complete assignments.

Chen Tianpeng did not expect that Ning Chen would hand in the paper so quickly. At this time, it was too late to call Ning Chen back, and he couldn't help but regret that he had not copied more just now.

When they saw someone standing up to hand in their papers, the students in the classroom also had surprised expressions.

Have you finished the answer so quickly? I haven't even written a third of it yet!

It's only been ten minutes. Even if you copy the answer, it won't be so fast, right?

You should probably just skip the questions you don't know how to answer, but you're handing in the paper in such a hurry. Don't you usually want to do it?

He Sheng was a little surprised to see someone handing in his paper so early.

Although these questions are not too difficult, the speed of answering them is indeed too fast for a freshman who has just completed a new course.

Aren't you going to check again? He Sheng asked.
