She Becomes Ugly if She Doesn’t Study

At 2:40 in the afternoon, Tang Su came to the examination room No. 07 again.

At this time, the air conditioner was turned on in the classroom.

The temperature in the afternoon was several degrees higher than that in the morning, it was still cooler in the morning, and it was already over 30 degrees in the afternoon.

However, the air conditioner in this classroom is not particularly good. Even if it is turned on, Tang Su still feels a little hot.

After a while, the familiar process came. The invigilator began to issue answer sheets and paste the barcode. She carefully checked the information on the barcode, and then wrote her name, admission ticket number, and seat number.

At 2:55 pm, Tang Su got the paper for the math test.

This exam is crucial because math is an important subject that widens the score gap.

Tang Su also understood that whether the college entrance examination can be successful or not depends on the mathematics test.

After getting the test paper, Tang Su still did not solve the problem immediately, because she had to wait until 3:00 to start the test, so she browsed the test paper, 12 multiple-choice questions 60 points, 4 fill-in-the-blank questions 20 points, 6 short-answer questions 70 points The points are the same as the usual exam questions. Tang Su took a look at the short answer questions. Question 17 examines trigonometric functions, question 18 examines solid geometry, question 19 examines conic sections, question 20 examines functions and derivatives, and question 21 examines sequence and probability statistics. , Problem 22 is the proof of inequality of inspection.

Tang Su was stunned. It's not that there is any problem with the knowledge points examined in this test paper, but the order in which the questions appear is different from the real test papers in previous years and the mock papers they usually test.

Usually, the 22nd question is a derivative question, and the 21st question is a conic section. These two questions belong to the finale questions. We also focus on two modules as difficult training, but this time, the conic section question is 19 questions, and the derivative The 20th question, which means that the difficulty of examining these two sections may be reduced, and the two questions of sequence and probability comprehensive questions and inequality proof questions have become the finale questions, which means that the difficulty of examining these pieces of knowledge has increased. big.

Tang Su took a deep breath. She took a sip of water and was shocked. To be honest, she really didn't expect to get such a math test paper.

Tang Su looked at the other candidates again, and found that some candidates were frowning, others sighed again, and even one candidate suddenly said:

"Fuck, what kind of paper is this. The teacher who wrote the question died with a household registration book."

The student was warned by the invigilator immediately after speaking swear words.

"Don't talk during the exam, keep quiet, and if you don't listen to the warning twice, it will be treated as disrupting the order of the exam room." The invigilator preached very sternly.

Soon, it's 3 o'clock.

As soon as the bell rang, all the students began to answer the questions.

Tang Su also immediately picked up the pen and began to do the question.

She thought that since the test papers were released like this, she would need to be more flexible and change her strategy for answering questions later.

The first six questions are relatively simple. Although the idea of ​​​​the question is novel, the questions are not too difficult. Tang Su quickly figured out the answer. Starting from the seventh question, Tang Su felt that the difficulty of the question increased a little, the angle of the question was more tricky, and the amount of calculation became larger. It took Tang Su a few minutes more than usual to complete it.

However, when she completed the 12th question of the last multiple-choice question, Tang Su was stunned, because there were no answer options she calculated, which meant that she did it wrong.

Tang Su then recalculated according to his own thinking, but the calculated answer was still the original answer.

Is she thinking wrong?
