The topics in the blue book are very comprehensive! It can be said that it contains all the questions of comprehensive mathematics, but some questions are more difficult. If you can learn this blue book thoroughly, there is no problem to get full marks in mathematics. I only used this book in the intensive stage and made it twice. When Mr. Wang Jietong talks about this book again in class, he will also expand a lot of contents and put a lot of test-taking skills! This book has many problems in every kind of topic, unlike other books, which have only a few problems, so it is also very suitable for brushing topics. Comprehensive mathematics needs basin tactics, not sea tactics, so we should understand the topic by type! After learning this book, you will find that many topics will have shadows in this book after doing simulation questions. After a period of training, you can find that your grades have improved obviously. Xinquan 1000 is a kind of examination paper. The first half is relatively simple, and the second half is a bit difficult. Suitable for brushing questions and practicing hand feeling, some too difficult questions don't have to be too entangled.
