After handing over the system, the state forced me to study

"I hope that since you have decided to participate in the math competition, you can adjust your mentality, instead of making a mess of even a test paper. After yesterday's test paper is handed out, you can see what the hell you are doing, especially Some students have very good test scores." Guan Lianyi said very seriously.

Lu Xingyao lowered his head, not daring to look at him. He had a feeling that the last sentence of Guan Lianyi was referring to himself.

He did not know a lot about yesterday's exam. Since the monthly exam, his study has been centered on textbook knowledge. As for the knowledge of Olympiad, he has no other knowledge except for the "Olympiad Tutorial" that he made on a whim during the holidays. touch.

As Lu Xingyao expected, he failed the exam.

Looking at the test paper with a large score of 79 in his hand, Lu Xingyao felt frustrated for the first time.

This is the first time he has failed an exam since he was bound to the system.

Thinking of scratching his ears and cheeks during the exam, and his eyes darkened when he saw the questions, Lu Xingyao couldn't help but fell into doubt. Can he really complete the system task this time?

After only half a month of study, there are countless contestants in the province, and some are even experienced and knowledgeable competition bosses. Can he really stand out among them?

Xu saw Lu Xingyao's skeptical life, or Guan Lianyi already knew the truth of giving a stick and a sweet date, and he continued: "Some students have never been in contact with competitions or Olympiads. It is normal to score such a score in one test, as long as you study hard, listen to the class well, and work hard yourself, then your grades will definitely improve in the future."

"Okay, I won't talk nonsense, I will start to talk about the test papers next, and in the process, I will explain the knowledge points involved in the competition to you again."

The explanation of the test paper made Lu Xingyao forget all his sorrows and sorrows. Since he is behind others, he needs to work harder.

"Let's look at the first question. In the space Cartesian coordinate system, what is your first reaction when you see these words?"

There were sparse answers in the classroom, "Draw a picture."

"Yes, draw pictures, I don't care if you have a good imagination or not, draw them on draft paper for me. Some students have learned a lot, so don't forget the most basic things..."

Lu Xingyao listened carefully, and silently wrote down the steps of Guan Lianyi teaching on the test paper.

1. Drawing

2.…

Guan Lianyi is worthy of being a senior teacher who has led more than ten math competitions. His lectures are not only as simple as explaining the questions, but also expand the knowledge points of the questions and the direction of the competition questions.

In his explanation, Lu Xingyao knew that geometry requires proficiency in the use of basic knowledge, that is, the transformation of poles and poles, collinearity of three points, and collinearity of three points.Knowing that algebra has great uncertainty, the diversification of inequalities, the diversification and combination of methods, and number theory are all possible.

除此之外，关连意还给出了一个供大家参考的时间规划，40+35+5或者35+35+10。

Lu Xingyao was determined to try which one was more suitable for him when he went back.

省级数学竞赛包含一试和二试，一试包含8道填空题(每题8分)、3道解答题(分别为16分、20分、20分)，全卷满分120分。

The second test includes 4 answer questions, involving plane geometry, algebra, number theory, and combination. The first two questions are worth 40 points each, and the last two questions are worth 50 points each. The full score is 180 points.

Guan Lianyi recommends that everyone can use the above schedule for the first test, but he does not have too many requirements for the second test.

He said: "The second test requires many exams to find the answering rhythm and test strategy that suits you, but the so-called rhythm and strategy do not mean spending 2 hours on one question, or seeing number theory and combinations. Lose."

Number theory and combinatorics are the two most difficult topics in mathematics competitions.

The content of number theory is abstract, difficult to understand and varied, and it is not easy to find a breakthrough. Many topics are similar but the methods are different.

The combination lies in the accumulation and associative ability, which needs to be solved by connecting the content of the test with the knowledge you have learned. It seems very simple, but it is not.The combination involves a wide range of knowledge, many methods, and various question types and models, which cannot be solved overnight.The knowledge points that many combination questions need to use are actually very simple, but they require more discussion and bold guesses.

For these two types of questions, Lu Xingyao only listened with his ears, and his heart was pounding.

In fact, he didn't solve these two questions in yesterday's exam. At that time, he felt that he could, but he couldn't.

I have a little idea, but when I actually start writing, I have no way to start.

Guan Lianyi also understood the shortcomings of the participating students in this area, so she explained in detail.

A training session, two hours, ended soon.

Before the end, Guan Lianyi said something like this, "In the first week, the training class is from 5:30 to 7:30, and I will explain the content involved in the competition to everyone in these two hours. If you want to get good grades, you need to go home or even use other time to study."

"But it's only for this week. From next week, our time will be adjusted. After school at 5:20 pm, we will give you an hour to go home for dinner. At 6:20, we will concentrate on the lecture hall on time. From 6:20, we will continue to At 9:20, we will have a trial-and-two-test crazily brushing questions and explanations, and during this period we will also talk about knowledge points, but it will be more concise, so don’t pin all the ways to learn knowledge on the teacher’s lectures.”

To put it bluntly, Lu Xingyao glanced at the dazzling 79 on the test paper, and understood the direction of his efforts.

Learn the knowledge first, and then do the questions.

Follow the rhythm of Teacher Guan.

In the next week, Lu Xingyao used the materials he bought to the extreme.

In addition to the materials recommended by Xu Chaoyang and the others, Lu Xingyao also bought two other materials with the help of the learning support group, "Lectures for Propositioners" and "Research Tutorial".

The "Olympic Mathematical Tutorial" done during the holidays can be regarded as laying a foundation. Lu Xingyao has a general understanding of a lot of knowledge. During the holidays, he only read and did it for the purpose of understanding, and it was not detailed enough, so Lu Xingyao decided to start Revisit this book.

After all, it is a book he is familiar with, so it seems naturally much faster. He memorized the answers to many questions in the book when he read it during the holidays. Although the value of practice has been lost, the value of learning is still there.

At this time, Lu Xingyao couldn't help thanking himself for his improved IQ and memory. He could basically understand many knowledge points by reading the principles and examples.

As for whether it can be used flexibly, it depends on whether the subsequent exercises can keep up.

One week, half a night of self-study, Guan Lianyi said so, but he didn't restrict students to contact him one-line to ask him questions. Lu Xingyao also asked a few questions, but found that there were too many people asking, and the waiting time was too long. He simply asked the people in the study support group directly.

The people in the study support group are worthy of being real materials. Not only can they answer Lu Xingyao's questions, but they can also answer them very clearly.

In fact, what he didn't know was that these members had all attended training courses and contacted about explaining skills, just to wait for a certain day, when Lu Xingyao needed them, they would be able to explain professionally, clearly, and clearly.

For a week, Lu Xingyao frantically absorbed water like a dry sponge. Even the remaining 14 bottles of Learning Concentration Potion were used up by him, and he kept 5 bottles for later use.

With his own efforts and the help of the learning support group, Lu Xingyao gradually gained a deeper understanding of competition knowledge.

The game knowledge base in his mind is also expanding.

A week is enough to change a lot. From Lu Xingyao's silent and frowning face at the beginning of the class, to his positive and quick response later on, these changes were all noticed by Guan Lianyi.

Not only him, but the performance of other contestants is also seen by him.

Some senior high school students who came here with the attitude of testing the waters were invited out of the training class by Guan Lianyi because the knowledge of the competition was too difficult, their usual attitude was lax, and they did not listen carefully in class.

There is such a precedent that everyone is nervous, studying with their tails tucked up, not daring to show a trace of laziness.

Under the change of everyone, the learning atmosphere of the training class also began to become more intense.
