The self-study exam only studies the contents and subjects of the exam.
And full-time undergraduate students will learn many basic subjects.
There are also differences in the study of the same subject. Some university study textbooks are combined with the current school reality, so that the unified textbooks are the same for the self-taught textbooks of any school. There is a general gap in universities.
However, the gold content of the self-taught examination is very high, and some students even learn more than all three students.
Work hard. Self-taught exams can be recharged.
