If you are a senior one at present, don't be too nervous. Don't stay up too late, go to bed early, get up early in the morning. The air is better in the morning, which can help you think, see what's wrong with you, and think hard during the day.
The following is the part about the competition. About the competition, the preliminaries are better, mainly to examine the understanding and depth of the knowledge learned. In this case, besides the solid knowledge in class, we should also look at some creative questions. The following is the rematch part. Before the rematch, some experimental counseling will be organized, mostly in the laboratory rented by the nearest university. In this case, it depends on your learning speed and adaptability. Most key middle school students will have some special teachers to guide the experimental part before the rematch, but most of them can only study in group counseling, so they suffer, but it doesn't matter, the experimental part will not be too difficult, usually just some difficult things like twisted gratings, and other electromagnetic things are generally not much.
Let's start with the first prize. I participated in it several times when I was a child, but I got nothing in the end. Anyway, the final was dark. Because the school was not among the national key middle schools, it was told that it was not qualified to participate in experimental training, and was later taken away.
Finally, advice, put a calm mind, don't take it to heart, summon up courage to take the college entrance examination with everyone, and you will feel nothing when you look back later.
Good luck!
