Liu's "Light One" is really poorly compiled. Many of the subjective questions in it are memorizing things, and rarely involve letting you draw inferences to deal with problems, which is exactly what CPA exams like to examine.

I also highly recommend Fan's second grade. When I first took Fan Qing's second grade, my professional ethics were all wrong in the third chapter. Fan's topic is famous for its difficulty and partiality, which opens your mind well. There is basically no memory of these things. It would be disappointing to take an examination of the basic skills of auditing and then appear in the topic. Of course, if I don't do the topic of the model, it may not be impossible to pass the examination. Everyone's situation is different, but I personally recommend Fan's second grade, and strongly recommend not to buy it.
