I've recently bought GMAT800
2006-2007 edition because I read everywhere that it was a very challenging material to get prepared for >700 scores.
I have following critics:
Indeed the verbal part is somehow more difficult, but not as expected. I'm doing right now the SC and CR1000, and I must say they are of better quality and many are much harder.
The quant part is not so difficult.
They just compiled the difficult problems from their other books/cdrom!
The book is big, heavy but in quantity poorly filled.
eg: For the RC, the same text is repeated on all the pages where questions are asked. I believe it is to be more convenient for the reader, who doesnt have to turn the pages back. So typically one question for RC takes one page!
For the CR, 2 pb/pages and the explanation/answer takes almost one page each.
Moreover, there are huge white/blank areas which could have been easily filled with text.
3. The last and big problem is that this book takes problems from Kaplan
regular gmat book 2003 and from the cd room. I had 3 CAT left, now I assume it will distort the results. Thus, I stopped reading the book to not make the things worse.
Conclusion. I paid 21Euros for this book which doesnt bring any added value compared with the kaplan
material I had already. same advices, problems... And for hard pbs, I just need to go in the 1000s and one questions....
For info, until now I worked on OG10
and 11, kaplan
CD, 1000 docs and didnt start yet the PR CATs. I worked at the beginning with Cliff CAT and Barron, but they are not worth to work with(verbal part)
I wd be interested to read your opinion about it.
