At 12:10 p.m. on the 13th, the math section, the second period of the 2026 College Scholastic Ability Test (CSAT), ended.
The CSAT question-setting headquarters issued References on the direction of the second-period math questions that day, saying it "avoided complicated calculations," and noted it aimed to write questions that "require a thorough understanding of the basic concepts covered in the curriculum and comprehensive thinking skills, rather than items that can be solved by simply applying technical elements or formulas obtainable through repetitive training."
Test-takers solve Math I and Math II as common subjects and choose one among Probability and Statistics, Calculus, and Geometry to take the test. Math I and Math II have 11 questions each, and the elective has 8 questions, for a total of 30 questions.
In the common subjects, there were two 2-point questions, ten 3-point questions, and ten 4-point questions. In the elective subjects, there was one 2-point question, four 3-point questions, and three 4-point questions. Of the common subjects, seven questions, and of each elective subject, two questions were short-answer, and answers were set to be natural numbers with up to three digits.
Questions corresponding to "Math I" included ▲ graphs of exponential and logarithmic functions (No. 22) ▲ understanding of the sine and cosine laws (No. 14) ▲ inductive definition of sequences (No. 16). In "Math II," questions included ▲ limits of functions (No. 21) ▲ drawing the basic shape of a function's graph and solving problems using it (No. 9) ▲ applications of definite integrals of functions (No. 15).
In "Probability and Statistics," one of the elective subjects, questions included ▲ understanding of combinations with repetition (No. 30) ▲ understanding of conditional probability (No. 28) ▲ the relationship between the binomial distribution and the normal distribution (No. 29). In "Calculus," questions included ▲ understanding of geometric series (No. 29) ▲ differentiation of functions expressed with parameters (No. 27) ▲ volume of solid figures (No. 26). In "Geometry," questions included ▲ positional relationships between a hyperbola and a line (No. 26) ▲ inner product of two plane vectors (No. 30) ▲ meaning of orthogonal projection (No. 28).
