Is to decide what kind of English you will learn in the future. All the tests are the basic knowledge of high school. Don't be afraid. Everyone basically played a holiday and didn't remember anything.
Also, if you want to enter the intensive class, you should have exams in mathematics and physical chemistry in science, intensive classes in liberal arts and the application of political history, as well as exams in English. Haha, don't worry, it's not difficult, but it's better to be mentally prepared.
