College students should enrich themselves during the summer vacation, such as reading books for next semester, learning some computer skills, joining some volunteer groups and doing some volunteer activities.

1. Many schools will buy their own books for next semester in advance. You can review next semester's books and see which one is more difficult. If you need to spend more time studying, you can study in advance, and it will be easier to get started after school starts.

2. You can learn ps, Excel, word, ppt, etc. And you can take the grade certificate in this field. These skills are also necessary for students.

3. Take part in volunteer activities, for one thing, you can exercise yourself, and for another, you can increase your volunteer time.
