I bought both the verbal books but after skimming once through both I decided that Kaplan
was better for me. Its surprising because I also have GMAT gudie with CD's both from Kaplan
as well as Princeton and I actually like more the one from Princeton because the explanation is better in Princeton.
But in case of verbal work book I did not like the one from Princeton because the explanations are not as good also I found the english very poor.
I am using Princeton GMAT GUIDE with CD plus Verbal work book from Kaplan
for the first round of preparation for Verbal.
