In short, the result of the so-called offline education is that everyone gets together to take classes online, and the teacher doesn't give lectures at all.

The learning environment is also extremely poor. The old computer card, the whole class shares a network, and the online class loads for a while. It can be said that the education in the Martian era itself is a complete scam, selling you hundreds of dollars of online classes and selling you tens of thousands of dollars.
