Very good!

Good Value for Money combined package, i.e. the book + CD + Online Materials with many exercises that help a lot when practicing. While the professor is giving the class there are other teacher in the room just to answer the students questions and also if we have questions after class we are free to send them an e-mail and they answer us very fast.
The topics and responses are discussed in great detail. There is an immaculate Foundation and Content review chapter under the AWA section as well, which is probably the best feature of this product. It also discusses the pacing strategy (writing the essay within 30 min) and nuances of Scoring.
The Foundation and Content Review Chapters under both, Quant and Verbal sections are very detailed and beginner friendly. The theoretical coverage on the topics is fairly detailed.
The answers to the practice questions, in the book, are very detailed and insightful.
Practice test are of paramount importance for test prep. The six tests equip the user to perform SWOT analysis and monitor progress from time to time. The test analysis report is a lifesaver!
