Chapter 587 The exam is quite difficult
At three o'clock in the afternoon, the math test began.
Tang Su took a deep breath and started to do the questions.
She has learned all the math knowledge required for high school.
But she had forgotten some of the things she learned in the first year of high school.
So when doing the questions, Tang Su had to try hard to recall some formulas from time to time.
She didn't do very well, the main problem was that she had forgotten some knowledge and some formulas.
Out of 120 minutes, Tang Suguang spent 60 minutes on the multiple-choice questions and fill-in-the-blank questions.
Then she started to solve the problems.
The first question was about statistics and probability. Tang Su finished this question very quickly because he had learned probability and statistics this semester.
The second question was about the comprehensive application of trigonometric functions. After Tang Su remembered the formula, he quickly solved it.
The third question tested the knowledge points related to space vectors and solid geometry. Tang Su also successfully answered this question because she had learned these contents in the first semester of her second year of high school and she had not forgotten them.
But when it came to the fourth question, Tang Su was a little confused, because this question tested a function synthesis problem.
Functions were learned in the first semester of the freshman year. Although they are now reviewing the content of the first semester of the freshman year, they have not yet reviewed functions.
Tang Su could only try to answer it, but she didn't know whether it was right or wrong.
The fifth question examined a comprehensive problem of conic sections. Conic sections were learned in the first semester of the second year of high school, and Tang Su still remembered the content of this section, but this question was too difficult. Tang Su answered the first question and gave up the second question.
The sixth question examined the comprehensive problem of functions and derivatives. This question was more difficult, and Tang Su spent more than ten minutes to answer it, and in the end he only answered the first question.
The math test is over.
After finishing the test, Tang Su shook her head helplessly because she only did 135 points of questions in total.
After about two minutes, the score came out: 121 points.
Tang Su looked at the answer sheet and found that he had lost 10 points for question 6, 8 points for question 5, and 3 points for question 4. He also lost 4 points for the multiple choice questions and 4 points for the fill-in-the-blank questions.
Tang Su felt a little sorry because she actually got the multiple choice and fill-in-the-blank questions wrong. These were medium-difficulty questions, but she actually got them wrong.
Tang Su felt that the reason for his mistakes was that his foundation was not solid enough.
——
After finishing the math exam, Tang Su began to analyze the test paper.
After every exam, she needs to analyze the questions she got wrong, to analyze why she got them wrong, whether it was because she did not master the knowledge points, or remembered them wrongly, or was careless, or had a problem with her thinking angle.
Tang Su first analyzed the multiple-choice question he got wrong. This was a function-related question with a tricky angle that needed to be linked to practical applications. Tang Su felt that the reason he got this question wrong was a problem with his thinking. Because once the direction of thinking is right, it is relatively easy to answer.
Then came the fill-in-the-blank question, which was a question about number series. She remembered the formula incorrectly, which led to a wrong calculation.
As for the questions that followed, Tang Su concluded that his current thinking was not capable of answering these extremely difficult questions.
Tang Su felt that this math test would be quite difficult.
She remembered someone saying that the college entrance examination is difficult in odd-numbered years and easy in even-numbered years.
But judging from today's Chinese and math tests, the test questions for even-numbered years are not easy to take.
Sure enough, that odd-even rule is bullshit.
The teacher is right. We should not have this kind of mentality.
