Most American universities now offer distance education. If you apply, you can only rank according to the different requirements of each university. This kind of thing is not credible. Many students in China are superstitious about the top 200. In fact, except for the top 20 universities in the United States, the rankings of other universities are bought with money! The ranking of domestic universities is actually the same. There are many middle and high-end universities in the United States, with thousands, and the teaching quality is basically the same.
The time of distance education is generally equivalent to studying in the school, for example, the master's degree is generally two years. Of course, American universities adopt the credit system, so if you are diligent, you can theoretically shorten your study time.
If you consider studying abroad, you can recommend some American universities with all scholarships for free.
