Not difficult. Compared with the 20 14 national examination paper, the difficulty of this national examination paper has not changed much. The difficulty of science mathematics has been reduced, and the examination content focuses on basic investigation, with comprehensive knowledge coverage and prominent focus. The six sections highlighted in the traditional college entrance examination, such as trigonometric function, sequence and inequality, solid geometry, probability statistics, analytic geometry and function and derivative, are still the focus of examination, and the difficulty is appropriate.
