In 2023, the college entrance examination in Liaoning is moderately difficult, and most subjects in Liaoning are not difficult. Control the difficulty of the test paper comprehensively from the aspects of material selection and test design, so as to make it equivalent to the overall answering ability of students and let students play their due level. This year's Liaoning college entrance examination paper is moderately difficult, and it is consistent with last year's college entrance examination in terms of basic knowledge and skills, paper structure, topic setting and score distribution.
