1. If you really don't like this university and can't re-choose, then choose a favorite major.
To tell the truth, I have met some people who completely abandoned their four years because they didn't like college. It's not worth it. Because you wasted tens of thousands of tuition and living expenses, you wasted your four years. Maybe finding a major you like can make up for the regret of not going to your favorite school.
In addition to changing your favorite major, you can try to participate in more activities and practices during college.
In recent years, in addition to paying attention to studies, there are actually social practices and community activities to participate in. It is said that the university is a small society, and you will feel this very clearly when you participate in social practice and community activities.
You can choose a hobby you like, participate in related club activities and cultivate a new hobby or skill for yourself. You can also participate in other social practices, increase your knowledge and improve your ability to act. These practical activities may become your confidence in finding a job in the future.
Generally speaking, don't give up on yourself even if you can't get into your favorite university. After four years in college, you can always find your own meaning. There are also some vicious people who, after learning that they have been admitted to a university they don't like, directly choose to repeat their studies and take the college entrance examination again. If you have the courage to do so, you can do the same.
