Of course, I suggest you go to every class, but usually some students do all kinds of things, such as taking the postgraduate entrance examination, starting a business and talking about people.

You will find that some courses can really be skipped to save time, and of course, some time-saving courses are used to sleep and play games.

However, truancy is a knowledge, which is related to the teacher's roll call rules, learning difficulty, failure rate and so on.

So ask your senior.

I will skip classes less when I am a freshman, because the habit of high school and the freshness of going to college have not faded, but there will be fewer and simpler courses in my freshman year.

Don't skip class if you want to get a scholarship or go to graduate school.
