I mornically bought books 1-7 from eBay thinking they were actual ETS tests. (I think its kinda sleazy that the seller misleads people) I have Books 1-6 in pdf and Book 7 is just xerox copies. I tried a few questions and it was way too easy.
I wish I would have found this forum before I shelled out money to buy this.
I'm concerned that practicing with GMAT Plus might derail some of what Im learning in Kaplan
and Princeton books.
I'm more than willing to upload the pdf files to anyone that wants them - but I take no responsibility if they hinder your score. I haven't decided if I will use it or not.
