As a girl, if you want to go to a famous university in the future, I think you should not stare at high school for three years, but concentrate on junior high school, because junior high school knowledge is actually very important, which can lay a good foundation for your knowledge study in senior high school.
Secondly, if you carefully understand the growth experience of a young person, you will find that the better a person's academic performance, the better his academic performance will be from childhood to adulthood. I think it is very difficult and rare for a person to make rapid progress at a certain stage.
For a young man, if his academic performance in junior high school is not good, it is difficult for him to improve his academic performance in the advanced stage, because his academic performance has a lot to do with his study habits and his study methods.
Third, as a girl, if she wants to be admitted to a famous university, she must develop good study habits from an early age and constantly cultivate learning methods suitable for her, so that you will grow step by step and your academic performance will improve steadily. After high school, it is not too difficult to be admitted to an undergraduate college, and the probability of being admitted to a famous university is also great.
