It was evaluated that the common subjects in the mathematics area of the second period of the 2022 University Scholastic Ability Test (SAT), conducted today (18th), were similar to the June and September mock evaluations, and the elective subjects were generally more difficult.
This year's mathematics area was divided into common subjects and elective subjects (choice one among probability, statistics, calculus, and geometry).
Kim Jeong-hwan, a teacher at Hyehwa Girls’ High School in Daegu, said, “The difficulty of calculus is similar to that of the June/September mock evaluation, and probability and statistics among the electives,” said Kim Jeong-hwan, a teacher at Hyehwa Girls’ High School in Daegu, who analyzed problems in the mathematics domain. , the geometry seems to have been a bit difficult."
Young-il Jang, a teacher at the Cheongju tax advertisment, also said, "Probability and statistics were given a little more difficult than the September mock evaluation, and the highest difficulty problem in calculus does not look different from the previous CSAT, but students may have felt it difficult." It must have been difficult,” he explained.
A number of new types of questions were presented in both common and elective subjects.
In the common subjects, questions such as question 12 for inferring the shape of a continuous function graph that satisfies the condition were newly introduced, and in probability and statistics, calculation questions were asked to find the number of cases through inference.
Difficulty questions were also presented to secure discrimination.
Question 15 of the common subject fills in the blanks using the properties of circles and trigonometric functions.
Item 21, which finds a value that satisfies the sum of conditions using the sum of a sequence and an expression, and Item 22, which finds a cubic function that satisfies a given condition after inferring a function expression using the limiting properties of a function, were also selected as high difficulty items. .
However, the teachers evaluated that the number of difficult questions in mathematics decreased and the number of questions of medium difficulty increased instead of the mock evaluation in June and September.
Oh Su-seok, a teacher at Somyung Girls' High School in Bucheon, Gyeonggi-do, said, "The number of questions of medium difficulty increased and there were many questions to evaluate problem-solving ability through reasoning, so the ability to discriminate would have been sufficiently secured." It can be difficult,” he said.
Admission companies evaluated that the common subjects were particularly difficult.
Jongno Academy analyzed, "The common subjects were difficult and the elective subjects, probability and statistics, were given relatively easily.
Daesung Academy predicted, “It was more difficult than the math for the mock evaluation in September.” “The general subjects were more difficult from 2-3 point questions, and some of the 4 multiple-choice questions seemed unfamiliar, so the level of difficulty would have been high.”
