After a few attempts at the GMAT exam, I've decided to revamp my study plan. What are your thoughts on doing the online lessons/videos from GMAT PREP NOW, following its Study Guide, plus doing questions from the OG 12th Edition? Do you think this is more than enough? I have all the Manhattan and Kaplan books; however, are there any that you think I should definitely own aside from those? Also, I really need to boost my verbal score, what resources should I be using that will help me with this? Or are the GMAT PREP NOW ONLINE LESSONS enough? Your help and advice is greatly appreciated!
