She Becomes Ugly if She Doesn’t Study

At three o'clock in the afternoon, the math test started.

Tang Su took a deep breath and began to do the question.

She has completed all the mathematics knowledge in high school.

But she forgot some of the things she learned in high school.

So when doing questions, Tang Su tried to recall some formulas from time to time.

She didn't do it very well, the problem was mainly because she forgot some knowledge and some formulas.

In 120 minutes, Tang Suguang spent 60 minutes on multiple-choice and fill-in-the-blank questions.

Then she started to answer the questions.

The first question is statistics and probability solution. Tang Su did this question very quickly, because probability and statistics were learned this semester.

The second question is to examine the comprehensive application of trigonometric functions. After Tang Su remembered the formula, he quickly answered this question.

The third question examines knowledge points related to space vector and solid geometry. Tang Su also successfully answered this question. Because these contents were learned in the second semester of high school, she has not forgotten them.

But when it came to the fourth question, Tang Su was a little confused. This question was about function synthesis.

Functions were learned in the last semester of high school. Although they are reviewing the content of the last semester of high school, they have not reviewed functions yet.

Tang Su could only try to answer. As for right or wrong, she didn't know.

The fifth question examines the conic section synthesis problem. The conic section was learned in the last semester of high school. Tang Su still remembered the content of this section, but the problem was too difficult. Tang Su asked one question, and immediately gave up answering the second question.

The sixth question examines the synthesis of functions and derivatives. This question was even more difficult. Tang Su spent more than ten minutes to answer, and finally only answered the first question.

Math test is over.

After finishing the exam, Tang Su shook her head helplessly, because she only did 135 questions in total.

After about two minutes, the score came out, 121 points.

Tang Su looked at the answer sheet, and finally deducted 10 points for answering the sixth question, 8 points for answering the fifth question, and 3 points for answering the fourth question. Then, 4 points will be deducted for multiple-choice questions, and 4 points will be deducted for fill-in-the-blank questions.

Tang Su felt a little pity because she had wrong multiple-choice and fill-in-the-blank questions. These are questions of medium difficulty, and she did it wrong.

Tang Su felt that the reason for his mistake was that his foundation was not solid enough.

After taking the math test, Tang Su began to analyze the test paper.

After each exam, she needs to analyze the questions she did wrong, and analyze why she did it wrong, because she didn't master the knowledge point, or she remembered it wrong, or she was careless, or it was a problem of thinking.

Tang Su first analyzed the wrong multiple-choice question. This is a function-related question. The angle of the question is tricky and needs to be linked with the actual application. Tang Su felt that the reason why this question was wrong was a problem of thinking. Because once the direction of thinking is right, the answer is relatively easy.

Then there is the fill-in-the-blank question, which is a question that examines a sequence of numbers. She remembered the formula incorrectly, resulting in a direct miscalculation.

As for the answers to the questions that follow, Tang Su concluded that the reason was that his current thinking was not able to answer these very difficult questions.

Tang Su felt that the difficulty of the math test this time should be quite big.

She remembers someone saying that the college entrance examination is difficult in odd-numbered years and easy in even-numbered years.

But judging from the Chinese and math exams taken today, the exam questions for even-numbered years this time are not too difficult.

Sure enough, the law of parity is bullshit.

It's still right to tell the teacher, you can't have this kind of mentality.
