As a reference book, I suggest you use the encyclopedia of Li Yongle and Li Zhengyuan's comments. Chen Wendeng's is also good, but that topic is more difficult. I don't recommend you to use that just after reviewing.
Read through the textbook and review the whole book, and you can do Li Zhengyuan and Li Yongle's "600 Basic Pass Questions", which is said to be the foundation. Actually, it's not easy to do.
Finally, do real questions and simulate 400 questions. Review the whole book at least three times and do the real questions at least three times to get high marks.
