Planned enrollment
Correspondence education is included in the national enrollment plan (adult education plan, not general education plan), and self-study examination is not included in the national enrollment plan.
Educational system difference
Correspondence college is generally two and a half years, and junior college is also a two-year class. In reality, there are not many students who have started high school. The first person who got the self-taught exam was a college diploma. The self-taught training courses in some colleges and universities are set for 3 years.
