If not, poor grades are normal, otherwise it is impossible or abnormal.
Many people, or most people, are just like you, so they didn't get good grades in the past and they don't get good grades now. If this remains the case, it will be bad in the future. I'll be like this for the rest of my life.
What I want to say is that if you can really do one thing well, you can do everything well. Everything is different on the surface, but the essence is the same. So it can be said that people with poor grades have the same reason; People with good grades have good grades for the same reason.
Specific research my suggestion is:
1. 1. Don't be absent-minded in class. Listen carefully if you can. If you want to study while playing well, you are deceiving yourself.
Just study hard for 8 hours every day. Others can be arranged at will. It's just that many people often "study" for eleven or twelve hours or more a day, but it's always equal to zero.
The improvement of Chinese depends on your understanding ability, not rote learning. Usually read more extracurricular books to improve your understanding and writing ability. Chinese is more extracurricular. When you see a few flowers, you will find that you have really improved, really different. These are also the things that will really make you different in the future.
Remember more words in English. Grammar is the basic thing. You can bring a dictionary, such as the college entrance examination dictionary, and read some new words every day. Don't focus on rote memorization, focus on the number of times you remember words. In this way, you will make great progress by turning over the dictionary several times. It won't take you much time to do it. You can read the dictionary for half an hour every day. You can read the dictionary almost dozens of times a semester, and you can almost remember it. Then there is the need to practice listening. Practice makes perfect. It's about persistence
6. Others should pay more attention to books, including all courses in arts and sciences. When you know the content of a book, you are nothing. These don't take time. The problem is that you never take the time to do it.
7. Understanding physics is very important. Some basic principles of physics course seem simple, but even in your school, few people can really understand its meaning. Thinking takes time.
8. Chemistry needs to pay attention to lectures, read more books and take more notes.
In short, it is the same sentence. If you can do one thing well, you can do everything well, and the method of doing one thing well is the same.
