Don't regret the path you chose. University is a life experience. After graduation, you will find that a lot of knowledge learned in college is useless and even outdated. But you should know that the university gives you the main structure of this major, a systematic learning method and an attitude of thinking and solving life problems. If you understand, use these methods and attitudes to actively study and enrich yourself, and you will find that your life is different and your college experience is valuable. Good luck!
