Before and after the exam
Before the exam:
I was so nervous that my palms were sweating and my breathing became rapid. I've been thinking about the contents of the exam, wondering what I should do if I accidentally do a wrong question. I didn't know if I could do it well, so I kept reminding myself to calm down. But I really can't calm down. I feel like I'm about to explode.
After the exam:
I was relieved when the exam was over, but my heart was empty. I didn't know if I had really mastered the contents of the exam. I thought back to my performance in the exam and wondered what I would do if I got a question wrong. I began to worry about my future, wondering if I had the ability to do what I wanted.

lead acid and water
The correct way to add water to a lead-acid battery is to use a plastic funnel to slowly pour distilled water or Deionized water into the battery to ensure that the water does not splash on the battery casing or other components, and to avoid pouring water into the battery's charging port or other non-water-adding ports. After adding water, close the battery cover in time and screw it tightly to prevent the water from evaporating. Before adding water, first check whether the battery level is lower than the indicator line. Only when the liquid level is lower than the indicator line do you need to add water. Use distilled water or Deionized water to add water. Do not use tap water or other water containing impurities to avoid affecting the battery's working effect. When adding water, pour water slowly to avoid splashing on the battery casing or other components to avoid short circuit or other failures. Adding too much water would cause the battery to overflow, reduce performance, accumulate water in the box, and corrode. In serious cases, it might cause the battery to short-circuit. Therefore, it is necessary to add a small amount of water many times. It is strictly forbidden to add too much water to exceed the maximum liquid level.
