Hehe ... don't worry yet! ! You are about to enter the third grade. Generally speaking, learning depends on accumulation to develop your ability, but you should know that it is never too late to study. It is never too old to learn.

First of all, you must put your mind right. Since you want to take the key class, you have to work hard. If your English is not good, you must get up early every day. If you are not good at physics, you have to watch the class taught by the teacher and do a lot of exercises every day. Of course, the more you do, the better, but you should know that there are only a few questions in junior high school physics. At the beginning, you can show the physics book to the teacher and ask the teacher to give you the key points and the knowledge points to be tested in the senior high school entrance examination (don't worry, as long as you ask the teacher, the general teacher will tell you that you also have goals to strive for the key points, and you can know the results even if it is not important). Then find out these key related problems (as long as you look hard, you will find that these problems are essentially the same. If you are good enough, you can also write your own questions and predict what you want to take. Our universities are all like this, otherwise how can we be the first in the last month of the exam! ! )

As for you, you don't want to learn when you see a computer. Your school is not so advanced that no one can use a computer at school for a day. Go home and treat the computer as a relaxing game! ! !
