On the morning of the third morning of the 2021 college entrance exam, at Deokseong Girls’ High School in Jongno-gu, Seoul, examinees wearing masks are taking a walk during lunch.
In the 2021 University Academic Ability Test (SAT), the testing period in math was more difficult than last year’s SAT and September’s mock test, and Na-hyeong was tested at a similar or easy level.
This year, after the 2015 curriculum was applied, geometry and vectors were dropped from the math presumption as the first SAT, and Math I entered the question range again. It was found that a number of difficult questions were presented, such as the B-hyeong math high difficulty question and the medium difficulty in the forged form.
Professors from the College Admissions Counseling Center of the Korea College Education Council made such a statement at a briefing on the trend of questions for the math field test held at the Sejong Government Complex on the 3rd.
Kim Jeong-hwan, a teacher at Hyehwa Girls’ Secondary School in Daegu, said, “The number of medium-level and high-difficulty questions has increased in the form of math simulation, such as three 4-point high-difficulty math questions. points. Higher and higher ranked students would have felt a bit complicated because the existing geometric questionnaire was presented as a calculation. ”
Teacher Kim chose 5 questions, including 20-21 and 28-30, as the high difficulty math problem. He said: “In particular, questions 20, 28 and 30 would have been a bit difficult because they were presented as inference questions rather than simple concepts.”
In the case of Nahyeong Mathematics, the difficulty of the SAT was similar to last year’s SAT, but it was analyzed that the relative load would have been reduced because there were no questions about blank reasoning, which was difficult for students, or a fractal problem. It took a long time to solve problems.
Mangi Cho, a teacher at Pangok High School in Gyeonggi Province, chose “20 and 21, 29 and 30 are very difficult questions” and “Question 20 was a new type of question that requires knowing the relationship between derivatives and integrals, and question 30 contains absolute values. “It was a question that had to be verified and inferred for the differentiability and continuity of the function.”
On the other hand, the number of questions answered in common by Hyung-Ah and B-Hyeong was 7.4 more than last year. In Math I, a question asking if you can solve a simple inequality expressed as an exponential function (form five, seven-b), and a question asking if you can understand and use the law of sine and cosine (probably 10, B 28), it was asked whether it is possible to infer the true or false of the proposition using the properties of the graph of the logarithmic function (pretension type 13, type B 18).
In probability and statistics, a question that asks if the relationship between the sample mean and the population mean can be understood (6 hypotheses, 11 b) and questions about understanding the meaning of the normal distribution and understanding its properties (12 hypothetical, 19 b)), a question asking if it is possible to solve the problem by understanding the probability sum theorem and using it (imaginary type 19, B: 29), and if it is possible to obtain the number of original permutations (probably 26, B 15) This was the question.
Oh Su-seok, a teacher at Gyeonggi Somyung Girls’ High School, who was in charge of the overall review, said, “I think the 2/3 point question is of a similar type to the September mock assessment and the SAT. last year, so students who understand the basic concepts and principles accurately can solve it without much difficulty.However, it was somewhat difficult for the simulation type, which had many high difficulty questions in the field of calculus and many questions that required logical reasoning, “he said.” For the purpose of the revised curriculum, the subject matter content has decreased by 10%. There is a tendency to discriminate questions. For both Ga-hyeong and Na-hyeong, high difficulty questions may have a higher level of difficulty due to the low link rate of EBS questions. ”
