What about poor PE?
When you say that physical education is not good, don't you mean that your physical fitness is not very good? In fact, there is still one year, and there is time to change the status quo. Physical education was weak before high school, but suddenly it got better after college. I later recalled that it should be the running in the third year of high school that made my physical fitness better. I suggest you take 10 minutes off every night to study by yourself and run around the playground several times. You can jog, preferably with a running length of more than 800 meters. You must persevere and it should have an effect in a few months. Besides these, you can take part in more sports activities and play badminton and basketball with your classmates. Don't worry, you will find that your motor cells are gradually active.
