There are many postgraduate classes in the market, such as face-to-face, online schools and video classes. It mainly depends on what kind of remedial classes you are suitable for, and the one that suits you is the best.

I didn't go to that kind of face-to-face lecture, but signed up for an online school, Tiandao Postgraduate Entrance Examination. The advantage is that the class can be repeated, and the account can also be shared with friends who study and share the expenses. Another disadvantage is that you should control yourself not to play with your mobile phone while listening, because no one cares about you, and it is easy to pick up your mobile phone from time to time to brush the news and get distracted. Of course, you can also listen to it on your mobile phone, but the mobile phone will unconsciously pop up WeChat messages and get distracted. So this piece is relatively inferior, but it is much more convenient than face-to-face teaching. You can listen to the knowledge points many times, so don't worry about not understanding them once. There are also many online school courses, and even pirated videos are sold online, but I have seen that the quality is not very good, so this way is adopted. The word "heaven" sounds very positive, so I took this.
