Sufficient for DI part, QC more than enough
Reviewed in the United States on November 1, 2015
QC is covered in six units out of seven units. DI is covered only in the 7th unit of the book. In the beginning, i thought the book was a waste of time as i was concerned only on DI part. The book surprised me however. The QC part was written in a very lucid way. I could simply turn on the pages to finish all the QC part. Though i was not interested in QC part, i have to say that QC part helped me a lot. The DI part covered in 7th unit was more than enough for me. It had few worked out problems and simply three problems to solve. But those few examples and three problems details almost everything one need to crack the DI questions in the GRE. In short, i will like to say that the book was worth buying in my case.
