After passing the beginner exam, Chen Yin went to the crowd on the other side of the group that was promoted to the advanced exam.

Here is the main force of the queue, the line is so long, so Chen Yin has to stand at the end of the line and wait slowly.

During the time of waiting, Chen Yin gradually saw that the door was coming. If it is a skip within the same level, for example, if you skip the second grade in the first grade of the test subject, you only need to answer the paper.

And the content of the paper seems to be the same, so even if you don't ask the students who finished answering the questions in front of you, you probably know it - but there are very few people who are willing to tell others the type of questions.

When the fourth grade wants to be promoted to the advanced examination, you need to go through what Chen Yin has just experienced, answer the random questions of the examiner, and only if you answer correctly can you be promoted, and if you answer incorrectly, you can only wait for the next month.

Seeing the classmates in front of him leave one by one happily or depressed, it was gradually Chen Yin's turn to answer the questions.

"Huh?" Suddenly, the students who thought they had just finished the exam came to Chen Yin's side, "Are you ...... Chen Yin? ”

"Stanley?"

"Ha, yes, you remember my name." Stanley laughed, "But you seem to have made a mistake, and the no-one desk over there is the place to apply for the beginner's test." ”

"Oh, that's it, I'm done."

"Finished testing?" Stanley was stunned.

"yes, sign it for me, forget it?" Chen Yin shook his student card.

“…… So, what question did the priest ask you? ”

"A bit of a detour of the sum problem, 3 bags of grain, two bags of two bags weighed, and then given 3 weights, to calculate the weight of 3 bags."

"Ugh." Stanley crossed his fingers and thought for a moment, "It's a bit complicated. ”

"yes, I think so too, I almost got my brain wrong." Chen Yin nodded.

"Come on." Stanley patted Chen Yin's arm, made a cheering gesture, and then walked away with a frown, fiddling with his fingers as he went, muttering indistinctly.

“…… No, that's how it should ......."

The team shortened rapidly, and soon the students in Chen Yin's previous group completed the test, and it was Chen Yin's turn to go up.

The first paper he received, Chen Yin looked at it a little, and it was still 10 questions, but in addition to language and mathematics, there were also some simple natural knowledge in the subjects.

For example, the three states of water, the formation of rain and snow, animals and plants, and so on.

Fortunately, I learned a lot from little Susan before, and the questions were more inclined to common sense knowledge, so I didn't show timidity in the characteristics of some plants.

Soon, Chen Yin finished answering a total of 4 papers again, and won the opportunity to be promoted to the senior examination with a total score of 39 points. As for the question that was answered incorrectly, it involved a certain animal that Chen Yin had never seen or heard of, so it was understandable to answer it incorrectly.

In fact, the seminary is very lenient about promotion within the ranks, and if you answer 6 out of 10 questions correctly, you can be promoted to the next grade.

However, the assessment of the cross-level is very strict, and the question that the previous powerful student got was the growth cycle of wheat, and a question made him directly defeated.

Then it was Chen Yin's turn.

The teacher glanced at Chen Yin's student card and casually asked about the area of the central garden.

“…… I didn't pay attention when I came, how far is it from that side to this side? Chen Yin asked, pointing to the opposite side of the garden.

"Well, you're going to count it as 500 meters." The teacher was also speechless for a while, obviously he didn't notice the problem either, but fortunately he gave Chen Yin a definite number.

"Uh...... 785 meters. ”

"What?" The teacher was stunned for a moment, lowered his head and calculated carefully, "Although there is a bit of a mistake...... But it's right! How do you figure it out? No nonsense, no guessing! ”

"Error?" Chen Yin asked for a piece of parchment and calculated it with a pen.

500/2*3.1415927

"Uh, I won't write after 785.387175, right? Too much. ”

The teacher took Chen Yin's papyrus, looked at the numbers written on it, and then several people gathered around and discussed for a long time, until a long line formed behind Chen Yin, and the teacher who spoke before continued to ask:

"What does that number mean?"

As soon as Chen Yin came out of the word "...... faction", he realized that something was wrong. This is not the Earth, and the name of pi on the Earth is certainly different from here.

"Well, it's one, the number of pi."

"How did you get that number?"

"Ugh." How to explain it?

The word pi may be just a very common number in modern society, but here, these teachers attach great importance to this number.

"Well, did I pass?"

Seeing that Chen Yin didn't want to speak, several teachers exchanged a few words in a low voice, and signed for Chen Yin.

Then, Chen Yin took his student card and walked in the direction of the advanced examination to the real department, which made the entire hall noisy.

"Look over there, what does he want to do?"

"Want to jump two levels in a row?"

"No, it's level three, he started as a beginner before, I saw it."

“……”

Since he decided to get the qualification to enter and exit the Tower of Knowledge as soon as possible, Chen Yin didn't have time to care about the discussions of these people behind him, so he directly received an answer sheet and began to write.

This time, Chen Yin's answering speed was finally not so terrifying.

In the three academic years of the advanced examination, the first year is more mainland politics, the second year is geography, and the third year is more art.

There are many questions that Chen Yin doesn't know at all, so he can only choose not to answer. Fortunately, in the entire 30 questions, these questions that Chen Yin did not know the answer accounted for only a small part, so that Chen Yin could get away with it every time.

In the end, one of the questions that Chen Yin got was:

"A pile of flame fruits, whether it is a pile of 3, a pile of 4, or a pile of 5, there are 2 left in the end, ask how many flame fruits there are at least."

Since 3, 4, and 5 are coprime numbers, this problem is actually a problem for finding common multiples, 3X4X5+2=62.

After stumbling, Chen Yin finally entered the real department. Of course, this is not the end, Chen Yin still has several levels to break in front of him. When the real science was upgraded, Chen Yin finally encountered a problem.

Physics, chemistry, and mathematics problems also involve the square - the square of the square and the high multiple cannot be calculated by formulas, but can only be calculated by memorizing the commonly used square and square numbers, and then decomposing and calculating according to the numbers.

But the problem is that Chen Yin has already returned a lot of things to the teacher, which is fatal to calculate with a pen......

But fortunately, he still answered more than 60 points, but when Chen Yin was about to move forward to school, he found that the teacher who was reading the paper actually said that he was not qualified to answer the question!

After Chen Yin waited for a long time, and when all the candidates had completed the exam and gathered here to watch the excitement, a white-bearded old man came to the exam under the guidance of several teachers.

"Hehehe, no one has challenged the qualification to enter school for many years, I am optimistic about you, children, I am going to solve the question, are you ready?"

Chen Yin was stunned as he watched as the old man McCarthy winked at him.

“…… You ready. Chen Yin nodded, thinking to himself that these were all acquaintances, would they ask me a simple question......

"To give you a simple question, the diameter of the metal ball is 50 centimeters, I want to brush a layer of 3 mm thick paint on it, the comprehensive loss rate of air drying, dripping, unevenness, etc. is about 13.3%, ask how much paint is needed to brush 20,000 balls?"
