Only by taking peacetime as an exam can we take peacetime as an exam. This is knowing this and knowing that, winning every battle.
You can't be arrogant If you read it, you probably really don't know. It just means you have an idea. It depends on your computing power. There are many twists and turns in it, which need more practice to grasp.
I remember when I was in middle school, the worst thing I did was the college entrance examination a few years ago. You can tell at a glance that it is a college entrance examination question of a certain year. I just thought about what the teacher said and didn't analyze the conditions in the question. When I get nervous, I can't write anything. The reason is that after the teacher said it, he did not seriously deduce it and handed it over to the teacher. From then on, you should see the importance of practice. Some skills can't be practiced without hard work.
Learning is like this. As long as you do what the teacher says, practice and practice, you will find many problems. After solving them, you will gain a lot of experience and have more chances of success.
