How difficult is it for Americans to get into Harvard, MIT and other schools?

Your question is very vague, because there are no specific standards for entering a certain school, and there are great differences between different high schools, different races and different Americans, and different universities have different difficulties for different people. According to my observation, as an Asian, sometimes it may be much more difficult than at home, but for some schools, the opportunities will be greatly increased. It's hard to say. For details, you can go to CC to see how the conditions of people recruited by various schools are. I only know that your GPA is good, but EC looks a little weak to be honest. Which subject is the national competition award and what level has it reached? Can you explain it? If I just look at your description, I think the result of choosing a reliable school will not be bad, but if it is clearly Harvard MIT, I think there is little hope. This condition is basically met if you apply for top 10. However, it may be easier if there is less competition in high school. You can check your school's previous admission data. Don't you still have summer vacation? Try to apply for a summer program with gold content. Experienced you will have something to write when you apply, and it is also valuable to meet more powerful people.

It doesn't matter. How many high schools in China go to Harvard, Stanford or Oxford and Cambridge every year? What kind of school is that? Nanwai? Shangwai? Fudan middle school attached to the National People's Congress? Besides, I don't agree with you that the best people in Harvard are those who specialize in one subject. The so-called expertise and all-rounder are a bit vague. Profession does not mean that nothing else will stand out, but that one aspect may stand out. If nothing else is good, it will affect the development of single subjects. All-rounder doesn't mean nothing is good, but it may be a little more complicated than the average person, not without special skills. Finally, I want to say, don't come to Baidu to ask such questions. There are not many helpful answers. You should go to cc and ask.
