Chapter 79 Competition 2
However, the content scope of G7 is not limited to the first-year junior high school content as Zhang Wei thought. It is divided into several sections such as number theory, counting geometry and algebra, and involves various functions, probability, and analytic geometry, some of which are knowledge that is only learned in high school in China.
Although Zhang Wei always felt that her way of thinking needed improvement, there was no problem with her math level. She couldn't really sign up for the elementary school group. What would be the point even if she got full marks? The awards were based on the difficulty coefficient. If she wanted to participate, she should choose a big one.
When Zhang Wei told Teacher Mo Li that she decided to apply for the G7 group, Teacher Mo Li nodded and said:
"You're already a leader among your peers for having the guts to sign up for this group. Don't worry about the outcome of the competition; you still have time."
In the following period of time, Zhang Wei temporarily gave up the training of thinking mode, and focused on practicing according to the knowledge points of G7. He also found the real questions of previous years on the Internet to practice.
I have to say that the tactic of doing a lot of questions is the fastest and most effective way to improve your problem-solving speed and ability. After doing several sets of real questions, I made 40% mistakes at the beginning, and I had forgotten some of the previous knowledge points.
Later on, I discovered the pattern of the questions, which basically revolved around a few fixed types, so Zhang Wei immediately found his weak points and increased his practice, especially the conditional probability part, which Zhang Wei had almost forgotten.
However, the advantage of mathematics is the uniqueness of its answers. When you forget how to do something, you can use the answer to reverse the process, and then use the reversed method to do a similar problem to test it. Repeat this several times and you will be able to master it.
I don’t know if it’s a psychological effect, but Zhang Wei feels that the previous thinking training is indeed useful. Her problem-solving efficiency has improved a lot and her thinking has become clearer.
So much so that before the competition, she felt that she was confident of winning a bronze medal in the top 40%, and she might even have a shot at a silver medal in the top 20%.
Paris also signed up for this competition, and like her, she signed up for G7.
Zhang Wei did not specifically tell the Wilsons this time, as who knows if they can win the prize, and their attention is currently on Namier's ice hockey game.
Namier's club is going to a nearby state for a few days and needs a guardian to accompany them, so Emma has been preparing to go out and arranging household and work matters.
Moreover, Tifield is also the designated examination center for the AMO competition, so there is no need to prepare anything special.
The exam lasts one and a half hours and contains only two types of questions: multiple choice and short answer.
There are 15 multiple-choice questions with a total of 45 points, and the short-answer questions are divided into two parts with a total of 10 questions, one part with 25 points and the other part with 30 points.
Calculators are not allowed during the exam. This requirement is nothing to Zhang Wei, but for a large number of students from Country A, time is a problem as they have to complete all the questions on the exam paper.
Country A generally focuses on thinking training and does not pay attention to basic calculations, so Zhang Wei has an advantage in this respect.
It only took her half an hour to finish all the multiple-choice questions.
Zhang Wei stood out in the classroom, as almost all the students around her were middle school students. Although she had grown a little taller in the past two years, she was still far from being taller at the age of 8.
Paris was not in the same examination room as her, and Paris had grown to almost 1.7 meters tall. Standing next to her, the three-year age difference seemed like a generation apart.
She could feel the invigilator looking at her from time to time, but as she finished the test, she paid less attention to the outside world.
The questions weren't particularly difficult, but getting all the answers right wasn't easy. Zhang Wei's methods for some of the questions were shortcuts she'd learned from her teachers back home, and she couldn't remember the derivation process, so she wasn't sure if she'd lose points.
She was still a little careless when doing calculations, but she didn't have much time to check after she was done.
When the time came and she stood up to hand in her paper, she took a quick glance and found that there was still quite a lot of unfinished work. This would increase her chances of winning the prize.
It was impossible not to check the answers after the exam. As soon as she went out, Paris was already waiting for her at the door.
If Zhang Wei hadn't stopped him, he would have even wanted to go to Teacher Ethan's house to discuss it with him.
Then they checked the answers and found that they had different answers to only two questions, one multiple-choice question and one short-answer question.
Zhang Wei was very open-minded: "It's okay. Even if we are all wrong, it will only deduct 9 points. That means we can at least get 91 points."
"How can you guarantee that all the questions with the same results are correct?" Paris asked back.
Zhang Wei said confidently: "I have confidence in myself, and I also have confidence in your ability!"
"I hope so. If I can make it to the promotion tournament and win a prize, my chances of passing the interview will be even better."
Zhang Wei: Poor kid, it’s so hard to have a dad who is a big shot!
Zhang Wei did some calculations and felt that it was impossible for only 10% of people to get full marks, and they should be able to at least get into the 20%; if they were lucky, it was not impossible for them to get into the 8% and win the gold medal.
On the way home, Zhang Wei was very happy, feeling that the medal was right in front of her.
However, after Zhang Wei waited for a month with a happy mood, the result was far from her expectations.
Although both she and Paris qualified for the promotion competition, she only won the silver medal, which was the last one, and Paris only won the bronze medal.
At this time, Zhang Wei was not as calm as Paris. Are all people in Country A so good at math?
In fact, Zhang Wei overlooked one problem. She has always lived in a circle of white people, and her only friend of Asian descent is Paris.
In Country A, there are a large number of Chinese and Chinese Americans not only in New York City but also in other states.
She and Paris were considered good in Tifield, but in the huge circle of Chinese students, they were indeed not good enough.
Another reason is that this is a global competition. According to statistics, more than 20 countries are participating, including China and Singapore, which have strong mathematical foundations.
The last reason is that both of them were competing in a higher-level competition, and their opponents were all middle school students. Zhang Wei’s protagonist halo was indeed not that strong, allowing her to dominate everyone.
But at least I passed the preliminary round and qualified to go to Singapore to participate in the promotion competition.
Teacher Morrie was very satisfied and even called Emma to tell her, which surprised her. Charles also went home early to celebrate with Zhang Wei.
A Chinese chef was invited to come to the house to cook dinner. What surprised Zhang Wei was that this time the food was Sichuan cuisine.
Although the taste has been improved a lot, you can still taste the flavor of Sichuan cuisine. Only a little bit of chili was added, but Zhang Wei was actually upset by the spiciness. It seems that her sense of taste has deteriorated. She used to be a fan of heavy flavors.
