The price of graduate training courses should range from several hundred to 20,000 to 30,000, and some graduate training courses are even more expensive. I really feel that the postgraduate entrance examination still depends on myself, and the remedial class is only an auxiliary role. It is enough to apply for an online course for postgraduate entrance examination. The teacher can help you sort out the knowledge points, which is convenient and time-saving without going outside in class.
The main thing is to have your own plan, such as how many points you need to get into the target college, how many points you need to reach this score in each subject, how to review each subject, what stage you want to go to, and so on. You should make a plan for yourself and follow it strictly.
Good luck.
