Has anyone used the total GMAT Verbal by Jeff sackmann?? Is it really excellent for the GMAT Verbal?? How can I get both books from Jeff. I have written him several mails. But I have not gotten any response from him.
Yes, I've used his materials and was pleased. I thought the verbal was okay. I liked the math guide much better.
I'm surprised he hasn't responded. He usually responds within 24-48 hours.
