I don't agree with you. Your use of the word "waste" shows that you don't really understand the purpose of what you learned in college, which is terrible. First of all, we must see clearly what the purpose of our actions is from primary school to middle school to university. Have you ever asked yourself? Why should I study? Why do I have to go to college? Your parents, teachers and public opinion will tell you that there is no way out if you don't go to school. To be a successful person, you must go to school. Do you think so yourself? Haven't you ever had a doubt about these things? I can tell you categorically that in China, the education received at school is very obscure. At best, its purpose is to teach you a survival tool to adapt to the mainstream society. As human beings, we should think about life by ourselves and the authenticity of life. This requires you to read more books, not only books on study, but also philosophy and literature. You should learn to observe the world by yourself and find love and sentiment from it. All academic initiatives are based on interest, but if you don't fully think about life, you can't have a strong interest in a seemingly boring thing, so repeating a grade can't solve the problem in essence.

I said a little too much at once. I'm not confusing you. For reference only. You should weigh yourself. You should be an adult now. Don't live and study with a single university personality at such a proud age, otherwise it will be the biggest waste to figure it out after many years.
