If the school has a qualitative requirement for internship credits, that is, if you don't reach a certain internship credit, you won't get a diploma, then the internship must basically be completed. In this case, if you are not satisfied with the internship arranged by the school, you need to apply for interns from other companies you like. If passed, you can naturally explain the situation to the counselor, and most counselors will not embarrass the students at this point. After your internship in the company, ask the relevant personnel of the company to issue an internship certificate, which can be used as the material for the internship. If it is difficult for you to find an internship, you can only obey the arrangement of the school. After all, you still have to get a diploma.
If the school doesn't require internship credits, then you can ask the counselor that you want to cancel this internship for some reasons, such as review for postgraduate entrance examination and subject competition, so that you can set aside your internship time to do what you think is more important. But this is not to waste time on other meaningless things. I am a junior, and what I face is basically postgraduate entrance examination and employment. No matter which of these two aspects needs to spend a lot of time to prepare well, I will make good use of my time for my future.
Practice can be said to be an attempt for us to go to the society in the future, so that we can know in advance how to correctly handle various problems encountered in practice, including work and interpersonal communication, which is a kind of exercise for ourselves. So whether you are satisfied with the internship arranged by the school or not, I think it is necessary to have an internship.
