At present, there are not many kinds of remedial classes for postgraduate entrance examination, such as face-to-face teaching, video classes, online schools, online and offline, expensive, cheap, packaged, free repeat classes and so on. The most important thing is to see what you want to apply for. I prefer the online school, which was reported in Tiandao Postgraduate Entrance Examination Network. Because I have a poor foundation and have to go to work, the time of face-to-face teaching can't be coordinated. I'm afraid I can't keep up with the progress. People are listening to lectures, and I am listening to gobbledygook. So I first signed up for an online class to lay the foundation, and the foundation can only be improved if it is laid firmly, otherwise there is an old saying that the foundation is not firm. If the economy permits, you can also sign up for a face-to-face class in the future, so that two different institutions can complement each other, both in content and form. I hope my answer is helpful to you.
