First of all, if the students who are preparing for the exam have a high level of English, such as having graduated from English major and have enough time to prepare, there is no need to apply for the exam.

Second, the top students in high school have a good English foundation and high understanding because they have experienced systematic English learning in high school. In this case, you can try to prepare first, and then try to take the exam again. If you feel confident, you can review in depth to improve your score. If you feel uncertain after the exam, especially the time for preparing for the exam is limited, you need to report to the training class. It's definitely better to get a little guidance from the teacher than to be in the dark.

Third, if the examinee's English level is average (here mainly refers to senior high school students), if the English foundation in senior high school is not very good, the test scores are not top-notch, and the test scores are unstable for a long time, they will not be able to work hard on their own. Because if you insist on the wrong way of thinking, you will not only lose confidence because of the increasing blow, but also find it difficult to accept the change of thinking mode after entering the training class, which will be very painful and less malleable than when you didn't know anything at first.

4. If the candidates are studying in university, but they are not English majors, and they usually have little contact with English, it is also very necessary to report to the training class. Because after entering the university, if you are not an English major, the systematic study of English is definitely not as good as that of high school. Therefore, the reason for signing up for classes is similar to that of ordinary high school students.
