Is the remote video of the postgraduate entrance examination class the same every year?

Yes, the contents of public courses are basically the same. If you just want a tutorial video of public courses such as politics and English for one year, you can. Generally speaking, the remedial classes for postgraduate entrance examination only update part of the exercises and related contents of the counseling materials every year. The syllabus of public courses does not change much every year. The key is that you can practice more and summarize more.
