1. written in modules, with real questions as the main part and a few simulated questions, with high quality;
2. Multiple choice questions account for the majority, and the answers are easy. Obviously, there are no strange questions, which are suitable for laying the foundation;
3. Every question has an answer and train of thought analysis, which is not available in many materials;
4. The printed design leaves a large blank for the students to do the questions.
I recommend this book to many middle-level students, and it is also the mainstay in counseling. This is a series of books. I think other subjects should be compiled like math. I suggest you go to the bookstore and have a look for yourself before you make a decision.
