Also, you don't have a teacher's PPT. You won't be informed of any school activities or inter-departmental activities, even if you go, it will be embarrassing. As for whether to go and see your own thoughts.
You don't know the time of going to school, taking holidays and taking exams every year, that is to say, if the audience doesn't have enough contacts, then you are a transparent person. So you need a classmate to take you and provide you with some basic information.
The most important thing is that you have enough self-control. If you do well, you will learn more than some unified enrollment students (this is not just professional knowledge, so I won't say much about it, so be mentally prepared).
