hey....im in the same position as you.....going by whats on the internet, you should start with the OG....they have a special OG for verbal right? heard that is good.....also, gmatclub has some free ebooks....they might be useful....dont know how good they are...but atleast they'll give you extra material to practice....
I am starting the preparation for GMAT. From what I have read I have sort listed following material.
1. Official guide.
2. Manhattan Guides.
How I should be starting? Which to take first? I want to focus more on verbal section.
