Abstract: A high-quality academic support system for freshmen is an indispensable part of the cultivation of talents in colleges and universities. From the perspective of cultivating talents based on large categories, the construction of an academic support system for freshmen is facing many challenges, such as incomplete document guides, lack of venues and carries, inaccurate diagnosis of academic data of study situation, and low satisfaction of individual needs, etc. Taking Shijia College of Beihang University as an example, this paper explores the work path of the academic support oriented to “helping students to adapt to the study and life in colleges and universities and providing cognitive education for major selection”, and constructs the work system in which academic support institutions are established in a hierarchical and classified way, the role of “one-stop” student community is played, students’ academic performance is evaluated in a multi-dimensional and multi-level way, and core influence of academic support projects is enhanced. With the external force of the academic support, we can stimulate students’ internal motivation of active learning and self-improvement and self-reliance, and help students bring out their full potential and grow and prosper in a comprehensive way.
