The aptitude test consists of six parts, namely: Mandarin (Korean), Mathematics, English, Korean history, inquiry (social, scientific and professional inquiry) and second foreign language/Chinese.

Candidates must answer the part about Korean history, and the rest are optional, but candidates generally answer the other five parts except the second foreign language/Chinese.

In mathematics, candidates must choose one of the more difficult "Ga" (science) papers and the shallower "Na" (liberal arts) papers. The inquiry part consists of three parts: social, scientific and professional inquiry. Each part has four or five fields, and each field has two or three themes.

Candidates who take part in the inquiry part must choose one of the three parts, and then choose two subjects from this part to answer (two subjects cannot be selected from different parts to answer); Only candidates who have graduated from vocational high schools can choose the career inquiry section.

For the second foreign language/language part, candidates only need to choose one of them.

Ga Type () Volume: Calculus II, Geometry and Vector, Probability and Statistics. "That Type" () Volume: Mathematics II, Calculus I, Probability Statistics.

The aptitude test has 20 to 45 questions in each subject, and each question is a topic without sub-questions. Except for the short answer part of mathematics, other exam questions are multiple-choice questions.

Therefore, all subjects take the OMR answer sheet as the answer sheet, and the answers are filled in with the black "computer pen" (Mike pen) provided by the test center personnel, and can be corrected with white erasing tape.

The math part is divided into multiple-choice questions and short-answer questions. The answer to the short answer question must be a natural number within three digits, so there will be no answers to unnatural numbers such as negative numbers, imaginary numbers and square roots; The answer is to set a listening test in the English part of the column, with three different numbers for each question.

The recording was changed into a CD-ROM, which was sent to various test sites for on-campus broadcast. If the recording volume or sound quality is wrong, some examination rooms may suspend the examination.
