1, school requirements change. In the university stage, the breadth and depth of knowledge are greatly increased, and the professional direction is basically determined, so it is necessary to give full play to the initiative and creativity of the school. In colleges and universities, except compulsory courses such as public subjects, basic courses and specialized courses, all majors offer elective courses, and students can choose relevant courses according to their personal interests and abilities, which increases their free time and greatly strengthens their autonomy in learning. For example, students can choose their own courses, extracurricular lectures, academic reports, etc. To enrich themselves, and they can also use books and materials to dabble in knowledge and master scientific learning methods.

2. Changes in the living environment. After entering the university, students leave their parents to live independently. Many students are still far away from home and have to arrange their own daily problems such as food, clothing, housing, transportation and school. This requires students to adapt to the new living environment as soon as possible and constantly strengthen their self-care ability.

3. Changes in social activities. Compared with middle schools, college students' social activities have become colorful, and there are more and more competitions, interest groups and various societies, such as party organizations, league organizations, student unions and class committees. Students can allocate their time and energy reasonably according to their own characteristics and hobbies, actively participate in various campus activities and enrich their after-school life.
