Tests in this book are designed according to the format of actual tests. The book includes eight sets of mock tests and corresponding listening materials. The sec- tion for listening comprehension is in MP3 format. Es- sential information about the HSK is also provided. The selection of the questions will reflect the features of the new HSK tests. After completing intensive exer- cises, students can better their understanding of the language points, vocabulary, and grammar required, and gain a thorough understanding of the structure of the test. This book will allow students to be fully pre- pared to sit the test.
