In addition, some other schools (mainly the continuing education college of the examiner's school, or other private schools and further education schools with cooperative relations) will organize self-study classes, and some of them are in full-time form, but these schools are only responsible for giving you classes and training, and there is no trace of them on the graduation certificate you got in the end. Because for the self-taught exam, you can take the exam regardless of whether you choose to participate in the aid class or not, but if you have no confidence in the self-taught exam at all, you can find this way. Relatively speaking, the remedial classes organized by the School of Continuing Education of the Examiner's school are more realistic, because there may be many marking teachers attending classes in person, which can give you more key information about the exam.
