Primary and secondary schools, including senior high schools, will charge fees for online classes, and there will be professional institutions to do these things. Hiring famous teachers to help students achieve better mastery is a mode of remedial classes, but their fees are lower than offline classes, because teachers who normally enroll in an offline remedial class are not famous teachers, and they may also charge fees, about 2,000 yuan for 20 days, or even higher, and online courses are relatively much cheaper. It is about 1000 yuan, and the teachers are all teachers who have graduated from famous schools and have certain teaching experience, so online teaching in high schools and primary schools is still reasonable.
There is some controversy about online education courses at universities and higher levels, which means that various postgraduate counseling institutions on the market are the focus now. When some organizations publicize offline, they claim how many hours we have, and there are famous teachers to teach, but they never say whether it is online or offline. As a result, after you applied, you found that all the courses were offline, recorded and broadcast by teachers, and there was no face-to-face teaching by famous teachers. This is naturally unfair.
Education itself is an industry worth investing in. Whether individuals invest in themselves or make money through education, they all take advantage of a kind of information gap, because whether it is postgraduate entrance examination or related courses in primary and secondary schools, as long as you are willing to find them online, there are actually many free resources, but there are no official supporting services, so many things are what you think are worth, and if you think they are not, they are not worth that much money.
