Details: Li Li is a learning artifact. Not only can you see many UP masters' postgraduate entrance examination experiences, but also many UP masters have shared free videos of various subjects. Although some years are not updated in time, they are completely sufficient, especially in mathematics and English. For example, it is no problem to watch 2 1 video in 22 years. Don't worry about politics. During the summer vacation in July, there will be the latest video, so you can follow it.

For example, if I search Tang Jiafeng casually, many interview videos of Mr. Tang pop up, which are very complete.
