I am a graduate student of 2 1 and have landed. Personally, I feel that Li Yang's basic courses are not very helpful, and I feel that I am reading textbooks. Look at Qiu and Chen Jixiu after the basic class, and look at Li Yang's foundation after the class, but I suggest you strengthen it. Personally, I think it is very useful to summarize different types of questions and methods according to the test sites. At that time, when we took the exam, many original questions appeared. Everyone is for reference only, actually it depends on personal situation.
