Official GRE Super Power Pack Paperback – 16 April 2015

I bought these just in case I ran out of questions to practice. I'd recommend the Quant and Verbal reasoning book but not the main Official GRE book since most of the info there you can get from online research or other courses. Also, the book says it comes with four practice tests. However it is only actually two practice tests which are in the physical book. The other two come in the CD which is PowerPrep software that can be downloaded for free from their website.Given that these are books, you have to solve the questions and then look up the answers at the end of every question section. This can be annoying so I'd rather go for online courses. The questions themselves were good though and pretty much identical to the real test.
