It is wrong to compare the three. There are several types of adult continuing education, such as self-study, correspondence, TV University and distance education, all of which have undergraduate and advanced undergraduate courses.

What you should ask is which is better, self-study or remote.

Self-taught examination is more difficult than distance examination, and it is difficult to enter school. The daily examination management is strict, so graduation is naturally difficult. So, if you want to learn something seriously, take the exam yourself. People who are familiar with society will speak highly of the candidates.

But the reality is that full-time undergraduates are everywhere. Who cares what kind of learning form you become a human student? All belong to the same category.

Choose a relaxing distance and get a diploma. The degree certificate is so difficult that I won't mention it.
