However, that book has a big disadvantage that the printing quality is definitely not as good as 2 Li, and the paper quality is also very thin ... 13 I used a math review book when I took the postgraduate entrance examination, and some problem-solving skills in it are still very good and useful, and there are too many exercises.
Personally, I think the typesetting of the new math review book is still very clear. I read Li's senior math part a little bit messy, so I decided to choose a math review book when I bought it.
