Dude, I'm a few years older than you. I have been there before. Now that you realize that you are confused and now you want to change your mind, let me tell you my opinion. Many people come to college for fun and eventually graduate, but since you want to change and learn something, it's not too late to learn from your sophomore year. Freshman courses are very basic. To tell the truth, it doesn't matter much if you don't learn well, as long as you can study hard in the future. Many college courses are not difficult. Listen to the class, finish your homework before the exam and review carefully. In the end, you will find that you must have learned something. So I think, from now on, you should get up every morning, whether there is class or not, go to the classroom or study room in the first class, and read outside all day, whether in class or after class. If you feel tired at night, you can go back to the dormitory according to the time after class, and then you can play games at night. As long as you can read all day, you will make great progress. If you want to work harder, get up early, come back later and learn more. That's it.
