Is the result of high school in England a false certificate issued by the school? Will it be checked and refused?

The probability is very small, unless your grades are too fake or the school seal is wrong, you won't check them. Even if I did, I just called the school to ask. There are so many high schools in China, but the results of college entrance examination are basically not recognized abroad, for reference only. However, it is easier to enter a foreign university than to graduate. If the foundation is not very good, I suggest taking a preparatory class.
