The first kind of students are those who arrange their time very full and have great momentum, and can be called the king of the roll. They will actively answer questions in class with the goal of getting scholarships. Excellent grades, participate in various departmental activities after class, participate in competitions and obtain certificates. I stay in the library when I have free time. I'm basically a lone ranger, making full use of my time.
The second kind of students are more disciplined students. I will listen to professional knowledge carefully, fish in unimportant classes, join one or two interested clubs in the final exam, take part in interesting competitions, take the certificate of examination, not pursue scholarships, and not fail classes. This kind of students account for the majority.
The third kind of students are bad players. They let themselves go in the life without too many constraints in college. They always fish in class, occasionally skip classes, and sometimes even don't come home at night, and often fail at the end of the year.
