If you do well in the college entrance examination, do you not have to worry about language problems when you travel to the United States?

Of course not. The English we studied in the college entrance examination is different from the English we use in our daily life, because in real life, the English we speak contains a lot of spoken English, slang and even dialect English, so we did well in the college entrance examination. In real life, we may not understand some words or sentences.
