Don't go if you can. Online education is not too long to start. Compared with other adult education, it is relatively backward. Those who can go to college, it is best to go to college. I'm afraid the last three schools are much better than adult diplomas. As for the self-study exam, don't go if your academic performance is average or your consciousness is too poor. As long as one exam fails, you can't graduate, and it is much more difficult to get a degree than others. Many people haven't got it for five or six years, so it's hard to stick to it. I haven't heard of this kind of online education, so I suggest you consider it carefully.
