This is because Mathematics I covers the mathematical knowledge needed by the first-class disciplines such as mechanics and mechanical engineering. Mathematics I is not only suitable for the field of mechanical engineering, but also widely used in materials science and engineering, chemical engineering and technology, geological resources, geological engineering and other disciplines.

Mathematics is also an important basic subject for management science and engineering, which require higher mathematics. Therefore, choosing Mathematics 1 as the examination subject for the postgraduate entrance examination of mechanical specialty can lay a solid foundation for students and provide strong support for their future academic research and career development.
